The Optical subsystem:
• makes the laser beam and provides the deflection of the beam onto the SCREEN
• moves the laser beam across the SCREEN at a controlled rate to release the stored
energy in the PHOSPHOR
• obtains the image by capturing the light that was released and changing it to a digital
format
The Optical subsystem includes the following main components:
• LASER
• GALVO
• COLLECTOR and PHOTOMULTIPLIER TUBE (PMT)
