Model ES 1.0
1. INTRODUCTION
1.1 Introduction
With spatial resolution of one million pixels, 30 frames per second (fps), and dual channel
progressive scan readout, the Redlake MASD, Inc. MegaPlus Camera, Model ES 1.0, is well
suited for scientific and industrial imaging applications. The compact camera package operates
through an AIA connection to a host computer. The AIA interface connector, located on the
camera’s rear panel, sends eight-bit digital output video to the computer and receives control
commands from the computer.
Featuring an interline Charge Coupled Device (CCD) sensor array, the camera has
1,008 (H) x 1,018 (V) light sensitive elements (pixels). These pixels have a center-to-center
spacing of 9 microns with a 60% fill ratio. The Model ES 1.0/PIV camera has been modified for
use in particle image velocimetry. This model has an active pixel area of 900 (H) x 900 (V).
The camera operates continuously or in a triggered mode. Minimum exposure times of 0.127
milliseconds are possible with the camera’s electronic shutter. The frame rate is unaffected by the
exposure time. The camera has an output channel data rate of 20 MHz, which gives a maximum
frame rate of 30 fps. The camera requires only eight watts of power and can be connected to
many commercially available frame grabber boards capable of handling eight or ten bits of video
data. The ES 1.0 camera’s triggered double exposure mode facilitates Particle Image
Velocimetry (PIV).
In dual channel mode, the camera outputs two lines of the image simultaneously. The camera is
limited to single channel operation and 15 fps when ordered as a Redlake MASD, Inc. MegaPlus
Camera, Model ES 1.0/SC.
