See-Through Near-to-Eye Viewing Optical System
First Claim
1. A see-through near-to-eye viewing optical system, comprising:
- a light emitting diode (LED) illumination system for generating a light;
a polarizing beam splitter (PBS);
a pre-polarizer for concentrating the light to the PBS;
a post-polarizer;
an eyepiece;
a Liquid Crystal on Silicon (LCOS) panel for projecting an image to the post-polarizer and further to the eyepiece after receiving the light from the PBS, wherein the LCOS panel is an LCOS of the color sequential type or of the color filter type; and
a beam splitter for transmitting the image that passes through the eyepiece and an outside field of view to a user.

Abstract
A see-through near-to-eye viewing optical system, which can be used in a head-mounted augmented reality display system, is provided. The see-through near-to-eye viewing optical system of the present invention comprises an LED illumination system for generating a light and a pre-polarizer for concentrating said light onto a PBS. Then an LCOS panel receives and reflects said light towards a post-polarizer after generating an image. The light travels from the post-polarizer and passes through an eyepiece for magnifying the image, and continues towards a 50/50 beam splitter. Afterwards the beam splitter transmits said light and another light from the outside field of view to user'"'"'s eyes simultaneously and thus, the user can see what is shown on the glass screen while still being able to see through it.
