Imaging systems for eyeglass-based display devices
First Claim
Patent Images
1. An imaging system comprising:
- an optical axis;
a microdisplay centered on the optical axis that generates images;
a spherical mirror that is rotationally symmetric about the optical axis that collimates the images; and
a partial mirror beam splitter centered on the optical axis and positioned between the image source and the optical element that reflects the collimated images onto an eye of a user of the imaging system.

Abstract
Disclosed are imaging systems and eyeglass-based display devices. In one embodiment, an imaging system includes an image source that generates images, a optical element that manipulates the images, and a beam splitter positioned between the image source and the optical element that reflects the images onto an eye of a user of the imaging system, wherein each of the image source, optical element, and beam splitter are aligned along the same optical axis.
