Optical measurement system

An optical measurement system, adapted to measure optical parameters of an object to be measured, the object to be measured comprises at least two light-transmitting layers, and the optical measurement system comprises:

• a light source module configured to emit at least two measurement light beams toward the object to be measured, wherein the at least two measurement light beams are respectively incident on the object to be measured at different angles;
• a photosensor configured to receive a plurality of light spots formed on a sensing surface of the photosensor by at least two first light beams after the at least two measurement light beams are reflected by the object to be measured and by at least two second light beams after the at least two measurement light beams are refracted and reflected between the object to be measured;
• and
• a controller electrically connected to the photosensor to obtain positions of the light spots;
• and
• a lens disposed on an optical path of the at least two measurement light beams and configured to focus the at least two first light beams and the at least two second light beams on the sensing surface of the photosensor;
• a reflector disposed between the lens and the object to be measured on the optical path of the at least two measurement light beams;
• and
• a rotating and moving carrier configured to carry the lens and the reflector, adapted to move along an emitting direction of the at least two measurement light beams after exiting from the light source module, or to move along a direction perpendicular to the emitting direction of the at least two measurement light beams after exiting from the light source module, and adapted to rotate the reflector so that the lens and the reflector are located at at least two first displacement points at different times, and a reflecting surface of the reflector has different angles at the different first displacement points, so that the at least two measurement light beams are respectively incident on the object to be measured at different times,
• wherein the controller calculates the optical parameters of the object to be measured according to the positions of the light spots.
