Abstract

A light distribution characteristic measurement apparatus for measuring the light distribution characteristic of a light source is provided. The apparatus includes a plurality of detectors arranged so that they have a predetermined relative relationship with each other. One detector has a detection range at least partially overlapping a detection range of another detector adjacent to the former detector. The apparatus further includes a drive unit that drives a plurality of detectors as one unit to update a positional relationship of the plurality of detectors relative to the light source, and a calculation unit that calculates the light distribution characteristic of the light source by performing a process depending on at least one of a relative relationship between a plurality of detectors and overlapping of respective detection ranges thereof, based on respective results of detection that have been acquired by the plurality of detectors at the same timing.
