OPTICAL-CHARACTERISTICS MEASUREMENT DEVICE AND OPTICAL-CHARACTERISTICS MEASUREMENT METHOD

摘要

Disclosed are an optical-characteristics measurement device and an optical-characteristics measurement method capable of reducing a measurement load for optical characteristics of a material and performing a simple and high-accuracy measurement in a short period of time. An optical-characteristics measurement device (for example, a BRDF measurement device) includes a light irradiation unit (for example, a light source unit and a point light source) which irradiates a sample with light, and a light reception unit which receives light from the sample. The light reception unit has a light reception sensor (for example, a sensor array) including a plurality of photoreceptors, and light guide unit (for example, an imaging lens) which guides light from the sample to the light reception sensor. The light guide unit guides light from the sample to different photoreceptors among a plurality of photoreceptors according to the position and traveling direction of light on and from the sample.
