THREE-DIMENSIONAL LIGHT BEAM ACQUISITION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional light beam acquisition apparatus configured to acquire light beam information under a prescribed illuminating condition with space-saving constitution.

SOLUTION: The three-dimensional light beam acquisition apparatus comprises an imaging optical system and an illumination optical system. The imaging optical system includes: a first optical device that transmits light from a subject; a second optical device that is arranged on the optical axis of the first optical device, forms the image of the light from the first optical device; and an imaging means that acquires the light image-formed by the second optical device as the light beam information. The illumination optical system includes: one or a plurality of light sources; and a third optical device that condenses illumination light from the light source. The illumination optical system is configured to irradiate the subject with the illumination light condensed by the third optical device through the first optical device of the imaging optical system.
