Chapter 3: PI-MAX3 Image Acquisition
This chapter provides a high-level overview of how PI-MAX3 acquires, transfers, and
processes image data.
Figure 3-1 illustrates the primary components of an intensifier-CCD such as that
incorporated into the PI-MAX3.
Figure 3-1: Primary Components of an Intensifier-CCD
In the PI-MAX3 camera, the input image is focused onto the photocathode of an image
intensifier tube. The tube electronically amplifies the image and outputs it, much
brighter, as gray-scaled green light. That light is then coupled to the CCD using a fused
fiber-optic bundle from the output of the image intensifier to the front side of the CCD.
The image at the output of the image intensifier is translated to the input of the CCD at
the same size.

After being detected by the CCD, the image is read out to the internal
controller, where it is digitized, and then transferred to the computer for processing via
a high-speed data link.

information.
