Abstract
A light absorption examining device includes a laser light source that emits the pulse laser beam, a measuring unit that retains the measuring object and irradiates the measuring object with the pulse laser beam, a light receiving unit that receives the pulse laser beam transmitted through the measuring object and outputs a light receiving signal, a pulse generator that produces a single rectangular pulse at a time when a signal level of the light receiving signal output from the light receiving unit intersects a set threshold, a laser driver that supplies the produced rectangular pulse to the laser light source to emit the pulse laser beam, and a control/processing unit that determines an accumulated delay time and examines absorption of the pulse laser beam by the measuring object using the determined accumulated delay time, the accumulated delay time representing a delay in a production timing of the rectangular pulse.
