13. HDF Light Processor
13.1 Introduction HDF Light Processor
Light Processor
The Light Processor is the heart of the projector. The prism of the Light Processor splits up the homogeneous white light coming
from the Light Pipe into red, green and blue light. The video information on the three DMD’s is integrated with these red green and
blue light beams. The prism merges the three integrated light beams back in to one full color video image, which is projected via
the lens onto the screen.
Each DMD has its own formatting board (satellite board) which drives the micro mirrors to integrate the video signal into the light
beam. A lot of heat is produced during the integration of the video information. To protect the DMD’s for overheating the Light
Processor is equipped with a liquid cooling circuit. Each channel has its own cooling block.
The Light Processor is equipped with 4 temperature sensors. Each channel has one temperature sensor on its cooling block. These
temperature sensors helps to protect the Light Processor for overheating.
The red and green channel are equipped with three extended adjustment knobs to convergence the DMD with the DMD of the blue
channel which is the reference channel for convergence alignment.
The air gap between the prism and DMD is sealed to protect the DMD’s for dust. It is important to know that a misaligned light path
which re
fl
ects upon the sealing will damage the sealing very rapidly. At the bottom of the prism exit a “touch” sensor is mounted
to protect the prism against accidental lens movements. Note that the Light Processor Unit is equipped with a motorized shutter
(dowser) in front of the prism exit.
