<p><P>PROBLEM TO BE SOLVED: To provide a device for detecting the quantity of light and a method of detecting the quantity of light capable of detecting the quantity of light considering the angle dependency of spot light. <P>SOLUTION: When detecting the quantity of light in spot light emitted from an LPH 16 relatively, the sport light is diffused by a transmission diffusion plate 80C provided between the LPH 16 and a line CCD 80A, the diffused light is condensed by a magnifying lens 80B and is imaged on the light reception surface of the line CCD 80A, thus detecting the quantity of light entering the light reception surface. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
