Abstract: An optical system includes an illumination unit and an imaging unit configured to image a scene including at least one object into a first image and a second image by using Helmholtz reciprocity. The illumination unit is configured to emit light into at least one light emitting solid angle and the imaging unit is configured to receive light from a light receiving solid angle. The light receiving solid angle is at least as large as each of the light emitting solid angles.
