The Princeton Lightwave dual band camera is a one
dimensional linescan camera that utilizes two
independent sensors. Optically coupled to allow
simultaneous imaging in both visible (400 nm-900 nm) and
infrared (1100 nm -1700 nm) wavelengths.
Visible sensing is provided by a 2048 element
integrated CCD-MUX employing a dual channel video data
stream at up to 40 Mega Pixels/Second,
(CameraLink ® transfers up to 60 Mega
Pixels/Second) at line rates of up to 9.65 KHZ. CCD
elements are 14 m m wide.
IR sensing is provided by a 512 element InGaAs
photodiode array and CDS-MUX employing a dual channel
video data stream at up to 5 Mega Pixels/Second,
(CameraLink transforms up to 60 Mega Pixels/Second) at
line rates of up to 9.65 KHZ. PDA elements are 56
microns wide.
Pixels are optically aligned enabling simultaneous
imaging of both spectrums with a 4:1 resolution ratio.
(Pixel 1 of the PDA is coincident with pixels 1 through
4 of the CCD).
Image data is supplied to the user on two separate
CameraLink interfaces, which can free run, or be
triggered independently. Each CameraLink interface
operates in the “base configuration” as defined by the
CameraLink standard and support several programmable
data rates as well as two channel (taps) or single
multiplexed channel transfer. Data can be delivered as
12, 10, or 8 bit data.
The performance and reliability of this camera make
it well suited for industrial imaging applications.
The camera is supplied without a lens allowing the
user to adapt the camera to a particular application.
Factory set-ups and calibrations are performed to
flatten the sensor's dark and illuminated fields, (DSNU
and PRNU).
User field calibration functions are available to
compensate for the user's lens and illumination
non-uniformity.
