摘要: An optical output level of laser diodes is detected by a photodiode for each the diodes, and this detection used in feedback control thereby achieving stabilization levels diodes. Furthermore, gain diode bias are stored an EEPROM (nonvolatile memory), carried out according to arithmetic processing integrated circuit using such that malfunctions scanning device can be addressed rewriting EEPROM.
