Abstract: A retroreflectometer for non-contact measurements of optical characteristics of retroreflective materials from a range of distances includes a light source for emitting a light beam; a first moving mirror assembly for scanning the light beam; a collimating lens for collimating the scanning light on an illumination spot on the surface of the DUT; an imaging lens for receiving a reflected scanning light comprised of the collimated scanning light reflected from the surface of the DUT; a second moving mirror assembly for controlling a predetermined observation angle, wherein the first moving mirror assembly and the second moving mirror assembly moved in synchronization to maintain concentricity of the illumination spot on the surface of the DUT; a light collector for collecting the reflected light from the second moving mirror assembly; a processor including a memory for determining the optical characteristics of the surface of the DUT responsive to the collected reflected light.

Abstract: System and method for performance characterization of multi configuration near eye displays includes: a mirror; a lamp; a beamsplitter; a collimating and reflective lens for collimating light reflected from the beamsplitter and reflecting it back towards an image sensor having a view finder; a field-of-view (FOV) aperture to project light from the lamp onto the DUT through the objective lens; a video viewfinder digital camera for capturing an virtual image of the DUT; a spectroradiometers for performing spectroradiometric measurements on a captured image of the defined measurement area to characterize the performance of the DUT; and a controller circuit for characterizing performance of the DUT based on the spectroradiometric measurements.
