Beam angle sensor in virtual/augmented reality system
First Claim
1. A display system comprising:
- a projection assembly configured to emit light;
a sensing assembly optically coupled to the projection assembly and configured to measure at least one parameter of light incident thereon;
a control subsystem in communication with the projection assembly and the sensing assembly, the control subsystem configured to;
generate image data defining a color, intensity, and location of a pixel of virtual content;
cause the projection assembly to emit light corresponding to the pixel as defined by the image data;
receive measurement data from the sensing assembly indicating at least one parameter of the light emitted by the projection assembly;
modify the image data based at least in part on the measurement data received from the sensing assembly; and
cause the projection assembly to emit light corresponding to the pixel as defined by the modified image data.

Abstract
A virtual image generation system for use by an end user comprises a projection subsystem configured for generating a collimated light beam, and a display configured emitting light rays in response to the collimated light beam to display a pixel of an image frame to the end user. The pixel has a location encoded with angles of the emitted light rays. The virtual image generation system further comprises a sensing assembly configured for sensing at least one parameter indicative of at least one of the emitted light ray angles, and a control subsystem configured for generating image data defining a location of the pixel, and controlling an angle of the light beam relative to the display based on the defined location of the pixel and the sensed parameter(s).
