Abstract
A laser driving control apparatus includes: a driver that constant-voltage drives a laser light source that radiates laser light by supplying a pulse signal in which a plurality of pulses, each pulse width thereof being changeable, is generated at a predetermined cycle; and a controller that performs control to change the pulse width of each of the plurality of pulses so that a first change amount of the pulse width when a present-time pulse width is changed to a preceding pulse width prior to reaching a pulse width at which a target light quantity is obtained stably is larger than a second change amount of the pulse width when the present-time pulse width is changed to a target pulse width corresponding to a driving current at an ON time of the laser light source in a steady state in which the target light quantity is obtained stably.
