Spyder2 4k User’s Manual The white light calibration is performed next to determine the multiplication factors required to bring each pixel to the required value (balance target) for flat, white output. Video output is set slightly above the brightest pixel (depending on offset subtracted). For FPN (dark light) the value of all pixels must be between 1DN and 127DN. For PRNU (white light) the value must be between 128DN and 254DN.
Spyder2 4k User’s Manual To perform dark calibration: 1. Stop all light from entering the camera. (Tip: cover lens with a lens cap.) 2. Verify that output signal level is within range by issuing the command gl or gla (a valid range is 1-127). If the signal level is too low, adjust the analog offset (sao). If the signal level is too high, ensure that no light is entering the camera, reduce the analog offset or reduce the gain level (sg). 3. Issue the command ccf.
Spyder2 4k User’s Manual To perform a white light calibration: 1. Place a white reference in front of the camera. 2. Verify that output signal level is within range by issuing the command gl or gla (valid range is 128-254). If signal level is too low or too high, adjust the gain using the command sg. 3. Instruct the camera to perform a white light calibration using the command ccp. The camera will respond with OK> if no error occurs.

Spyder2 4k User’s Manual • Some light sources age; over their life span they produce less light. This aging may not be uniform—a light source may produce progressively less light in some areas of the spectrum but not others. Filters CCD cameras are extremely responsive to infrared (IR) wavelengths of light. To prevent infrared from distorting the images you scan, use a “hot mirror” or IR cutoff filter that transmits visible wavelengths but does not transmit wavelengths over 750nm.
Spyder2 4k User’s Manual object space correspond to each pixel in the image sensor. Using the preceding equation, the object distance must be 450 mm (0.450 m). 10 μm 45 mm = 100 μm OD 03-032-10195-04 OD = 450 mm ( 0.
Spyder2 4k User’s Manual 5 CCD Handling Instructions 5.1 Electrostatic Discharge and the CCD Sensor Cameras contain charge-coupled device (CCD) image sensors, which are metal oxide semiconductor (MOS) devices and are susceptible to damage from electrostatic discharge (ESD). Electrostatic charge introduced to the sensor window surface can induce charge buildup on the underside of the window that cannot be readily dissipated by the dry nitrogen gas in the sensor package cavity.
Spyder2 4k User’s Manual Dust can normally be removed by blowing the window surface using a compressed air blower, unless the dust particles are being held by an electrostatic charge, in which case either an ionized air blower or wet cleaning is necessary. Oil is usually introduced during handling. Touching the surface of the window barehanded will leave oily residues. Using rubber fingercots and rubber gloves can prevent oil contamination.
Spyder2 4k User’s Manual 6 Troubleshooting The information in this chapter can help you solve problems that may occur during the setup of your camera. Remember that the camera is part of the entire acquisition system. You may have to troubleshoot any or all of the following: power supplies frame grabber hardware & software light sources operating environment cabling host computer optics encoder Your steps in dealing with a technical problem should be: 1.
Spyder2 4k User’s Manual PRIN PRIN is an optional input signal used to control exposure control (PRIN). PRIN Indicates High Low Integration Pixel reset Data Clocking/Output Signals To validate cable integrity, have the camera send out a test pattern and verify it is being properly received. Refer to section D11 Generating Test Patterns for further information. 6.2 Troubleshooting Using the Serial Interface The following commands can aid in debugging.
Spyder2 4k User’s Manual • No test pattern or bad test pattern — May indicate a problem with the camera (e.g. missing bit) or a system setup problem (e.g. frame grabber or timing). Verify the presence of the LVAL and STROBE signals. • Test pattern successful — Run the svm 0 command to deactivate video correction. Then run the gl command under both dark and light conditions to retrieve a line of raw video (no digital processing).
Spyder2 4k User’s Manual 6.3 Specific Solutions No Output or Erratic Behavior If your camera provides no output or behaves erratically, it may be picking up random noise from long cables acting as antennae. Do not attach wires to unused pins. Verify that the camera is not receiving spurious inputs (e.g. EXSYNC or PRIN, if camera is in exposure mode that regulates external signals).
Spyder2 4k User’s Manual test pattern pixels (first 2 pixels following the last End-of-line pixel. You may need to turn the End-of-line sequence “on” by sending the command els 1). Any deviation from a consistent value of these pixels (170DN/85DN) could be an indication of the following: • shorted bits • stuck bits • digital noise pickup on the I/O cable • open connection. To activate the test pattern, use the command svm 2.
