Film Scan System Using a Semiconductor Light Source and Light Detector
The practicality of using a semiconductor light emitting diode and a semiconductor photo transistor in a film scanning system is proven by implementation. The use of these devices rather than an incandescent lamp and photomultiplier tube leads to a system using no high voltages, requiring no warm-up and having very long life with repeatable operation.
