The Sensor The LC3000-series cameras contain a high-performance, high-resolution line scan image sensor (PerkinElmer Optoelectronics parts RL0512PAG, RL1024PAG, or RL2048PAG) featuring a pinned photodiode pixel. Each photodiode converts incident light into discrete charge packets. Advantages of pinned photodiode pixels include lin- ear exposure control, the elimination of image lag, and the reduction of photo response non-uniformity (PRNU). For more specific sensor specifications and information, please consult the appropriate sensor datasheet. Figure 1a details the spectral sensitivity of the sensor, while Figure 1b details the sensor’s glass window light trans- mission curve. Functional Description The video signal from the sensor is processed through a single channel of sampled-and-held, raster order, analog video data. The video channel signal processing circuitry offers both adjustable gain and offset levels to allow customization of the camera to unique lighting applications. An operational amplifier in a differential configuration is recommended to receive the video signal. Figure 2 details the camera video processing. Operating Modes The LC3000-series cameras can be operated in one of two different modes: Master Mode and Slave Mode. Master mode is to be used when the LC3000- series camera is operating as a stand- alone unit. Master mode requires only input DC power (12-24 VDC) for operation. In this mode of operation, the camera will operate at its basic clock frequency (defined by the model number) and at the maximum line rate. Master mode operation is selected using the bank of rear-camera located 12586 Final Art 2 5/9/01 4:51 PM Page 2 |
