Abstract
An optical system for measuring a parallelism of rays of a light emitter and virtual imaging distances (VIDs) of the light emitter, the optical system including an enclosure, a pair of apertures, and a lens system disposed between the front and rear end of the enclosure, wherein a first and second of the apertures allows a first and second set of rays into the enclosure to be disposed through the optical lens system to be cast on an imaging plane as a first and second spot, respectively, wherein a parallelism of the sets of rays is based on a correspondence of a distance between the spots with a distance between sets of rays and a VID of the light emitter is based at least in part on an offset of the imaging plane from the lens system focus position when the light emitter is not optically disposed at infinity.
