| 英文摘要 | PURPOSE:To make the light emitting output of a light emitting element due to an environment variation constant by more finely varying a driving current stepwise than a pulse width of the driving current determined according to the light output of the light emitting element, adding both the outputs and impressing to the light emitting element. CONSTITUTION:A drive signal 17 id raised, a laser diode LD is set to a state capable of emitting light and a microcomputer 11 decodes the light emission output PO from the output 16a of a power detector PD. If the light emission output is larger than a standard light emission output PTYP, digital data 11a is lowered by one step, latched to a latch 2, and whether the light emission output PO is lower than the standard light emission output PTYP or not is decided, the operation is repeated until the light emission output PO is lower than the standard light emission output PTYP, and latch 1 latches the digital data 11a. |
