Fiber-optic module: This is used to couple the image that is generated on the phosphor of the image
intensifier to the CCD. Since the optical format of the image intensifier is 1” and that of the CCD
is 2/3”, a taper is used for the reduction.
High voltage power supply: This is used to generate the voltages that are necessary for the
performance of the image intensifier.
Intensifier control board: This board interfaces between the camera I/O board and the high-voltage
power supply. A serial interface is used between the I/O board and the controller chipset.
{Note: Over-exposure can cause permanent damage to the Intensifier tube that is part of the
Intensicam}
7.8.3 Spectral
Response
Standard and enhanced coatings are available to provide different spectral characteristics (see
Figure 7.8.1). The phosphor of the intensifier (which is fiber-optically coupled to the CCD) emits
in the blue-green part of the spectrum, which is well matched to the peak-response of the CCD.
The spectral response for the standard intensifier (and the extended blue version) are shown below;
enhanced coatings are available upon request.
