MotionMeter High Speed Video Camera PREFACE This manual describes how to operate and maintain a Redlake MASD, Inc. MotionMeter High Speed Digital Imaging monochrome Camera. The MotionMeter is used as a hand-held or tripodmounted unit. The camera records sequences of images from 60 to 1000 frames per second, depending on the model and setting. Images from the camera or from the Image Memory are displayed on the MotionMeter viewfinder and external monitor.

MotionMeter High Speed Video Camera 1 INTRODUCTION TO HIGH SPEED MOTION ANALYSIS The MotionMeter is a hand-held High Speed Digital Imaging Camera that records a sequence of images of an event at a frame rate of 60 to 1000 frames per second, depending on the model of video camera used. The camera stores these images in a digital Image Memory.
REDLAKE MASD, INC. 1.2 The Imager Responsivity Curves The camera has a TC237 monochrome CCD imager. The imaging sensor has an image area of 658 (H) x 496 (V) pixels, each pixel being 7.4 microns square. The imager has a built-in electronic shutter to limit the exposure, see Appendix C. All standard cameras have the CM500 1mm IR filter. The filter is omitted on the low light version of the camera. Imagers. Filters are installed at the factory and cannot be changed in the field. 1.2.
MotionMeter High Speed Video Camera 1.2.4 Spectral Response without the CM500 IR Filter This set of curves shows the spectral response for the red, green, and blue signals without an IR filter. See Figure 1-4. Blue Green Red Figure 1-4 Sensor RGB Spectral Response without an IR Filter. 1.2.5 The Monochrome (Gamma) Curve The Monochrome Curve shows the imager 8-bit gray scale with values from 0 to 255. See Figure 1-5.
REDLAKE MASD, INC. 1.3.3 Stopping a Recording using a Trigger Input The MotionMeter trigger input circuit detects a signal from an external source and stops the recording at the frame active at the receipt of the trigger. This enables you to record an event that either occurs very quickly, or happens without warning and when the camera operates unattended. You should always use the trigger if you want to have the event coincide with the Frame 0, since the Stop button has a propagation delay.
MotionMeter High Speed Video Camera 1.3.4.1 Synchronizing two or more MotionMeter cameras The cameras should be connected as shown in Figure 1-6. One camera is designated the Master and the other camera(s) are designated as Slave(s) in the Settings menu. Cameras are usually connected in series. The most common series connection requires a BNC cable to connect the Phase Lock Out from the Master or leading unit to the Phase Lock In connector on the next downstream unit.
REDLAKE MASD, INC. 1.6.2 Stop Recording using the Trigger The camera also stops recording when it receives a signal through the Trigger input. Recording stops at the frame determined by the Trigger Point setting, see Figure1-8. The trigger can be set from 0% to 100% in 10% increments to adjust the length of time the images show before and after the event that caused the trigger. The percent value represents the proportion of the sequence shown before the event.
MotionMeter High Speed Video Camera 1.7 Viewing the Image Sequence The video images from the camera in Live mode, or from the Image Memory, are shown in the viewfinder. To see the video sequence in detail, the pictures must be seen on a remote monitor connected to the video output through the Composite Out cable connector. The MotionMeter camera provides either NTSC or PAL video, selected by the Settings menu. 1.7.

MotionMeter High Speed Video Camera 2 DESCRIPTION OF THE MotionMeter CAMERA The MotionMeter is a Camera that records a video event in an internal digital memory, and replays the event at playback speeds from freeze frame, and 1 frame per second (fps) to 1000 fps in a 3.5” viewfinder on the rear panel. You can view the video images on an external monitor, or download and store each event on a VCR or a computer equipped with a video processor card.
REDLAKE MASD, INC. 2.3 MotionMeter Controls and Indicators All controls and the display are located on the back of the Unit. Symbols are used to show the functions except for the MENU and Select (SEL) buttons. Figure 2-1 The MotionMeter Controls. 2.3.1 The RECORD Button A momentary push button that turns the Record function ON. The screen shows the REC mode. All buttons except Stop are disabled during Record. The camera returns to Live mode when the Stop button is pressed. 2.3.
MotionMeter High Speed Video Camera 2.3.4 The MENU Button This momentary push button selects one of three states: 1. LIVE mode. 2. The SETTINGS menu. See the Settings Menu description below. 3. Menu OFF. This turns the Menu displays OFF and allows you to view the full video. If the Menu is OFF, press the MENU button to display the LIVE mode menu. 2.3.5 The SELect Button. This button selects the next parameter in the menu displayed. A white background identifies the active parameter. 2.3.
REDLAKE MASD, INC. normal state is high, and the signal goes low to activate the trigger. The triangle direction changes for each alternate range in the TRIGGER menu. 2.4.2 Record Mode. Press Record to start the Record function. The MODE indication shows REC and the external monitor displays the images. The camera records the images at the frame rate and shutter speed set until you press the Stop button. The event indicator increments by one each time the Record button is pressed.
MotionMeter High Speed Video Camera 2.4.4 The Settings Menu This menu shows the default settings for the Settings menu. The alternate selections are shown to the right in Figure 2-5. Select this menu by pressing the Menu button once in Live mode. Initially the first line is active; press the SEL button to go to the next line. Press the + or – button to change the selection. The settings are as follows: Figure 2-5 The Settings Menu. Master/Slave.
REDLAKE MASD, INC. 2.6 Power Sources to the Camera The camera requires a 12-volt DC power at 2 amps. This power can be obtained from the following sources: 2.6.1 Power Outlet Redlake provides a universal power supply that operates from a power outlet that supplies 90 to 240 volts. The power supply output has an output cable and DIN plug for the camera. The input cable has a standard IEC connector to the power supply.
MotionMeter High Speed Video Camera 3 UNPACKING AND CONNECTING THE MotionMeter CAMERA 3.1 Unpacking the MotionMeter Camera 3.1.1 List of Equipment Check that you have the following items in the MotionMeter package. • Camera. • AC power adapter with cord and power switch. • Carrying Strap. • Operator’s Manual. • Lens (optional). 3.1.
REDLAKE MASD, INC. 3.1.6 The Trigger Input The Trigger input is always enabled in Record mode. The Trigger circuit supplies a +3.3-volt level to the connector by way of a 10K pull-up resistor. The camera monitors the Trigger input and detects when a trigger signal is received from an external source. A trigger signal detected when the camera is recording stops the record sequence at a point determined by the trigger point setting.
MotionMeter High Speed Video Camera 3.1.7.1 Connecting MotionMeter Cameras to an Equipment Source One or more cameras can be synchronized to an equipment source. If there is more than one Slave unit, the connections can be series or parallel. See Figure 1-6, and substitute the equipment source for the Master unit. The Phase Lock signal level is +3.3 volts, which must fall to 0 volts prior to the next frame exposure. This signal’s rising edge causes the start of a frame exposure. See Figure 3-4.

MotionMeter High Speed Video Camera 4 RECORDING AND VIEWING IMAGES 4.1 Recording an Event Sequence The camera should be in Live mode with the live image showing in the viewfinder and the external monitor. 4.1.1 Camera Defaults When you turn the camera on for the first time, the menus show these default values: Record Rate: 60 fps. Shutter: 1X. Trigger Point: 100%. Event No: 0000. If you change these values, the camera retains the new values when it is turned off.
REDLAKE MASD, INC. 4.3.1.1 1. 2. 3. 4. 5. 6. 7. 4.4 Press the Record button. The new image is recorded over the existing image in the image memory. The camera viewfinder and monitor show the image being recorded. The menu indicates RECORD. All controls except the Stop button are disabled. Recording continues and the images wrap around the image memory. Press Stop to end the recording, or Supply a trigger signal. The camera assigns the active frame “Frame 0”.
