LIGHT DISTRIBUTION CHARACTERISTIC MEASUREMENT APPARATUS AND LIGHT DISTRIBUTION CHARACTERISTIC MEASUREMENT METHOD |
摘要 |
A light distribution characteristic measurement apparatus includes: a detecting unit for detecting light from a light source; a mirror for reflecting the light from the light source to direct the light to the detecting unit; a movement mechanism for moving the detecting unit and the mirror relatively to the light source; a rotation mechanism for rotating the mirror while maintaining an optical path length from the light source to the detecting unit; and a processor adapted to calculate the light distribution characteristic of the light source, based on a plurality of measurement results that are detected by the detecting unit under a condition that the detecting unit and the mirror are arranged at a plurality of measurement positions relative to the light source and the mirror is oriented at different rotational angles for each measurement position. |
