Fujifilm FCR XG-1 X-ray Laser Module Teardown (Part 2 of 3)

Part 2: Teardown of the laser scanner module from a Fujifilm FCR XG-1 x-ray image scanner / digitizer. Also known as Computerized Radiography (CR), it fulfills the job of scanning a x-ray exposed image plate. It uses a laser beam to extract each pixel illumination with a photo multiplier tube setup. It can scan 72
