Title: ENHANCED ILLUMINATION SYSTEM
Abstract:
An enhanced illumination system is provided. In some configurations, an illumination system comprises one or more illuminators for emitting light. Light steering optical elements direct the light along diverging axes. In some configurations, the camera module assembly can cause an output to be tilted down or tilted up relative to a horizontal plane. In some configurations, the illumination system comprises diffusers positioned to receive light along the diverging axes, each diffuser producing a field of illumination having a predetermined angle. The illumination system can be mounted on a computing device, such as an HMD providing a field of view to a camera, sensor, and/or a user. By the use of the techniques disclosed herein, an illumination system can mitigate optical loss that may be caused by a curved visor positioned between the illumination system and an object in the field of view.
