  • Optical device for measuring the optical properties of materials
    Patent number: 11567004
    Abstract: The optical device for measuring at least one of reflected light (BRDF) and transmitted light (BTDF) from a sample, in all spherical directions of space around the sample, for each spherical direction of incident light includes a light source, and a goniophotometer configured to measure at least one of: directions of the incident light in spherical coordinates, and directions of the reflected light in spherical coordinates. The device further includes a dispersive screen, and a multi-sensor imaging device. The goniophotometer includes a first articulated arm supporting the light source; and a second articulated arm supporting the sample or a sample holder.
    Type: Grant
