Optical Architectures for Displays and Sensing in Augmented, Virtual, and Mixed Reality (AR, VR, MR).
Temperature changes can detrimentally affect an optic’s performance due to changes in radius of curvature, thickness, and index of refraction. This is a particularly tricky problem when combinations of these changes produce a decrease in focus with
