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.
