X(3) POLYMER AGILE LASER FILTERS

PHYSICAL OPTICS CORPORATION (POC) PROPOSES TO DEVELOP BROADBAND PASSIVE LASER FILTERS WHICH WILL OPERATE IN THE VISIBLE AND NEAR IR PORTION OF THE SPECTRUM. THESE FILTERS WILL USE X(3) POLYMER MATERIALS AS THE KEY ELEMENT TO WRITE ESSENTIALLY INSTANTANEOUS (SUB-NANOSECOND) REFLECTION HOLOGRAMS AT THE PARTICULAR WAVELENGTH OF THE INCOMING LASER THREAT. PHASE I WILL INCLUDE ALL WORK NECESSARY TO ESTABLISH THE SOUNDNESS OF THE PROPOSED APPROACH, INCLUDING DEMONSTRATIONS OF THE SCIENTIFIC VALIDITY OF THE APPROACH. PHASE I WILL ALSO INCLUDE EXPERIMENTAL VERIFICATION OF THE PRINCIPLE PROPOSED. THIS WILL TAKE THE FORM OF A BREADBOARD DEMONSTRATION. THIS NEW TYPE OF FILTER WILL PERMIT A DEMONSTRATION OF THE EFFECTIVENESS OF THE APPROACH AGAINST ANY ARBITRARILY SELECTED VISIBLE OR NEAR-INFRARED WAVELENGTH (TO 1064 NM), AND YET SHOW ITS POTENTIAL FOR USE IN A LIGHTWEIGHT, HANDHELD DEVICE WITH A WIDE FIELD OF VIEW.
