Abstract
A system and a method for synchronously detecting thickness and double-side surface profiles that belongs to the technical field of optical measurement. The system includes a light source system, a deflection reflection system, a camera acquisition system, and a processing system. The deflection reflection system includes a decomposition unit and an integration unit. In the system, an optical signal is projected to an upper surface and a lower surface of an object to be measured by the decomposition unit, and then reflected light is converged by the integration unit to form a composite signal, which is captured by a camera to generate an image. The processing system analyzes the image to accurately obtain the thickness and double-side surface profile data of the object.
