US 11,445,155 B1 · Display system with angularly separated lasers

Abstract

Display systems, such as near eye display systems or wearable heads up displays, may include a laser projection system having an optical engine and an optical scanner. Light output by the optical engine may be directed into the optical scanner as two angularly separated laser light beams. The angularly separated laser light beams may overlap at an entrance pupil plane along a first dimension at a first scan mirror of the optical scanner, or at a location between the first scan mirror and an optical relay of the optical scanner. The angularly separated laser light beams may overlap at an exit pupil plane along the first dimension at a second scan mirror of the optical scanner or at an incoupler of the laser projection system.

Dependent claims

A laser projection system comprising:

an optical relay configured to receive and relay a first laser light beam and a second laser light beam, wherein the first laser light beam and the second laser light beam are to be angularly separated when the first laser light beam and the second laser light beam are scanned into the optical relay;
a first scan mirror configured to scan at least one of the first laser light beam and the second laser light beam into the optical relay;
and
a second scan mirror configured to receive the first laser light beam and the second laser light beam from the optical relay and to scan the first laser light beam and the second laser light beam, wherein the first laser light beam and the second laser light beam are to converge along a first dimension to overlap at the second scan mirror.
