Analog Line Scan Camera
Description (cont.)
applications include lumber processing,
parcel scanning, non-contact measure-
ment, document scanning, dimensional
gauging, biomedical imaging, bar code
scanning and many other industrial
and scientific applications.
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
