65‐1: Distinguished Paper: Photometric and Colorimetric Measurements of Near‐Eye Displays

Abstract

We discuss the optical system design concepts for properly measuring the photometric and colorimetric characteristics of near-eye displays. Measurements on various near-eye displays demonstrate the variance in instrument results due to their optical design. Based on these findings, optical instrument design guidance is given for the proper measurement of virtual image displays.

65‐3: Spectroradiometric Measurements of Near‐Eye and Head Up Displays

“…Recent work has been done that defines a minimum essential set of measurement instrument optical system characteristics to assure repeatable and reproducible photometric and colorimetric measurement results. [1] Building upon these findings, we give a more detailed investigation of the effects that large (5 degree) to small (0.1 degree) areas of the visual field of view have on spectroradiometric measurement results. We also look at the variation in the luminance and color measurements resulting from positioning the measurement optical system entrance pupil in different areas of the design eye box.…”

Advanced Optics for the Evaluation of Near‐To‐Eye Displays

“…In consequence, with an NED design, its XP must be reachable by the iris. The eye box concept discussed by Penczek et al 3 suggests a certain axial and lateral space to place the iris. The reason is the diameter of the NED‐XP, which could be much larger than with classical optical instruments.…”

“…One reason is the manifold of NED‐architectures 1 and their ongoing changes 2 . A luminance measuring device (LMD) that uses only a single element detector provides integral results inside the captured FOV 3 . Photometric cameras, also known as array detectors in International Committee for Display Metrology (ICDM) display measurement standards, use either an imaging luminance measuring device (ILMD) or an imaging color measuring device (ICMD) to provide a 2D‐distribution of measurement results, and enable spatial allocation to the emitting display.…”

38‐1: Transverse Chromatic Aberrations in Virtual Reality Devices

“…However, the application of these devices for highly technical tasks also raises new questions concerning the suitability and performance of the devices. In recent years, considerable effort has been placed on developing methods for characterizing the radiometric [14,15], colorimetric [16,17] characteristics of the HMDs and on methods for the alignment of the user or measurement system to the HMD [18][19][20][21].…”
