Abstract
An object detecting apparatus detects an object by using a laser beam emitted from a laser diode. The apparatus has a current adjuster. An amount of electric current supplied from the current adjuster to the laser diode is controlled to change an intensity of the laser beam, and is adjusted by a feedforward control based on a signal from a temperature sensor in the apparatus to compensate a drift of the laser diode characteristics.
