Buffer for image data
After the AD conversion, the image data is preprocessed in the FPGA,
multiplexed (4:1) and sent to the image processing card in the Main-PC.
Operator surface
English shortcut for Light amplification by stimulated emission of radiation
A semiconductor diode working in the near Infrared range in which the
recombination of electrons and spaces at the p-n transition between a p and
an n-conductive semiconductor material is used to generate and amplify light
(see Semiconductor laser).

Laser Feedback
The adjustment of the density-proportional image data to the paper to be
exposed is performed in the LUTs, taking into account the laser properties and
the transmission characteristic curves of the AOM amplifier.
The memory of the Printer Mainboard can save LUTs for 2 paper types at the
same time.
Image data interface (differential pairs of lines) between the CG-Controller and
the image processing board in the Main-PC.
The pixel correction (Piko) is used to level the individual pixels of the CCD
chip so that the black value (dark current) and the white value (sensitivity)
are identical / reproducible for the subsequent signal processing.
Light filter to alter the intensity of the spectral composition by using the
polarisation condition of the light
Rotating mirror to deflect the beam into the exposure unit PE
CCD pixels: The dark current rises beyond a constant but pixel-dependent
dark current rate linear with the scanning time. Owing to the sampling
process, additional pixel-dependent voltage differences occur which are not
time- and light-dependent (so-called PRNU).
Interrupt routine (FL-Controller) for the motor control:
The Controller can generate PWM by itself. In this case, the Controller gets an
Interrupt whenever a new pulse is generated. However, not all IO-Pins of the
Controller can be operated in this mode. The other Ports have to be controlled
in the CC mode.
Motors (FL-Controller): Filter wheel negative, KG filter paddles, wheel of the
auxiliary shutter, film drive
Motor (CG Controller): Shutter
Serial interface between the Motherboard and the Main PC.
The SPI module (Serial Peripheral Interface) controls the magazine drive.
