Title:
EXPANSION OF FIELD OF VIEW
Document Type and Number:
WIPO Patent Application WO/2019/075235
Kind Code:
A3
Abstract:
An implementation of an optical system for expanding the field of view can include a first optical element and a second optical element. The first optical element can include a first surface and a second surface. The first surface can be configured to reflect a first light beam incident on the first surface at a first incident angle greater than a first predetermined angle, and the second surface can be configured to reflect the reflected first light beam towards a location. The second optical element can include a third surface and a fourth surface. The third surface can be configured to reflect a second light beam incident on the third surface at a second incident angle greater than a second predetermined angle, and the fourth surface can be configured to reflect the reflected second light beam towards the location. The optical system can be configured to shift an image laterally from a first region to a second region, the image characterized by the first light beam and the second light beam. Related apparatus, systems, techniques and articles are also described.
