Optics Module Control Board
This board, located in the laser enclosure, routes the analog drive signal and + 9 volts dc from the MCS
Board to the drive circuits that operate the laser diode (see Sheet 2 of the system diagrams in Section
10). In addition, it contains a slave micro and auxiliary circuits that control the Optics Spinner Motor and
Attenuator Motor, and report status to the Master CPU on the MCS Board. It also houses the SOS
Detector and Beam Power Monitor circuits.
Parameter EEPROM
----The EEPROM for the Slave Micro contains the following information, which is
loaded during manufacturing:
•
Serial number for the Optics Module, which can be in the range from 0 to 65535.
•
Start of Scan (SOS) Delay Time, which can be in the range of 0 to 255 pixels.
•
Identification of the polygon mirror facet (0 or 1) to which the pixel stretch value must be applied.
•
The value for pixel stretch, in the range of 1500 to 61556.
Note
You can use the SERVICE TOOL to display the EEPROM data:

Spinner Motor Control
----The Spinner Motor scans the laser across the film, as it is reflected
successively from the two mirror facets in the double scan process. Turn on and speed of the motor are
controlled by the slave micro on the Optics Module Control Board. The speed control signal (SERIAL
CLK) from the slave micro is fed to a DAC. The analog output of the DAC is amplified and used as a drive
signal for the Spinner Motor.
SOS Detector
----During each revolution of the scanner, a photodetector on the Optics Module Control
Board is activated by the laser beam reflecting off a spot on the scanner adjacent to mirror Facet 0. Thus
Facet 0 is used as the reference for Start of Scan. The SOS signal from the detector, shaped and
amplified, is sent to the Pixel Clock Generator on the MCS Board to be used as a timing reference (SOS
RAW) for pixel flow control. The detected SOS signal is also used by the Beam Power Monitor on the
Optics Module Control Board, as described in the next paragraph.
