Abstract: A system and a method for calibration of optical measurement devices are described. In one embodiment, the optical measurement device comprises an imaging lens, and the calibration system includes a projection light source, a lens module, and a projection element. The light emitted from the projection light source passes through the projection element and is projected by the lens module, and then captured by the imaging lens of the optical measurement device. The exit pupil of the lens module in the calibration system is coincident with the entrance pupil of the imaging lens of the optical measurement device, providing a compact and highly efficient optical calibration mechanism.
