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.
