INTEGRATED OPTO-ELECTRONIC DEVICE AND PORTABLE REFLECTIVE PROJECTION SYSTEM
First Claim
1. An integrated opto-electronic device used in a reflective projection system, comprising:
- a reflective polarizing composite film configured to receive a source light at a desired non-normal incident angle, polarize and reflect a first portion of said source light as polarized illumination light at a reciprocal angle to said desired non-normal incident angle; and
a photovoltaic cell, adhered to an opposite side of said reflective polarizing composite film to said source light, configured to receive a second portion of said source light that passes through said reflective polarizing composite film and transform said second portion to photogenerated charge.

Abstract
An integrated opto-electronic device, a portable reflective projection system and a method for in situ monitoring and adjusting light illumination are provided. The device includes a reflective polarizing composite film (150) configured to receive a source light (210) at a desired non-normal incident angle (221), polarizes and reflects a first portion (211) of said source light (210) as polarized illumination light (16) at a reciprocal angle (222) to said desired non-normal incident angle (221); and a photovoltaic cell (180), adhered to an opposite side of said reflective polarizing composite film (150) to said source light (210), configured to receive a second portion (212) of said source light (210) that passes through said reflective polarizing composite film (150) and transform said second portion (212) to photogenerated charge. Unused illumination can be collected in order to re-store and reuse recovered energy.
