Authentication System And Method

View page
US Patent:
6744909, Jun 1, 2004
Filed:
Aug 19, 1999
Appl. No.:
09/377257
Inventors:
Andrew A. Kostrzewski - Garden Grove CA
Gajendra D. Savant - Rancho Palos Verdes CA
Tomasz P. Jannson - Torrance CA
Joanna L. Jannson - Torrance CA
Assignee:
Physical Optics Corporation - Torrance CA
International Classification:
F06K 900
US Classification:
382115, 382210, 382278, 356 71, 359 11, 359561, 359577, 36911201
Abstract:
An authentication system using a correlator that correlates an input with a reference wherein at least one of the input and reference comprises a phase volume mask having structures, preferably points, that are each less than about six microns in size and can have an aspect ratio (AR) greater than 1:1 so as to produce a phase encoded random pattern having millions of combinations in a mask that is as small as one square millimeter. The random pattern can be convolved with a second pattern, such as a biometric pattern, to produce a phase convolved mask. The correlator preferably is a nonlinear joint transform correlator that can use âchirpâ encoding to permit the input to be located in a different plane than the reference. The correlator optically Fourier transforms images of the reference and input that are thereafter nonlinearly transformed and inverse Fourier transformed by a processor to determine the presence or absence of a correlation spike indicative of authenticity. A spatial light modulator (SLM) can be used as an input or reference and preferably is a liquid crystal panel having pixels or elements whose phase or grey scale intensity can be selectively controlled by a processor.

US Patent:
60725516, Jun 6, 2000
Filed:
Jan 13, 1997
Appl. No.:
8/782962
Inventors:
Tomasz P. Jannson - Torrance CA
Joanna L. Jannson - Torrance CA
Stephen A. Kupiec - Torrance CA
Jack L. Latchinian - Torrance CA
Assignee:

High Channel Density Wavelength Division Multiplexer With Defined Diffracting Means Positioning

View page
US Patent:
49264125, May 15, 1990
Filed:
Feb 22, 1988
Appl. No.:
7/158396
Inventors:
Tomasz P. Jannson - Redondo Beach CA
Joanna L. Jannson - Redondo Beach CA
Peter C. Yeung - Redondo Beach CA
Assignee:
Physical Optics Corporation - Torrance CA
International Classification:
H04B 900
US Classification:
370 3
Abstract:
A wavelength division multiplexer/demultiplexer having optical path lengths between a fiber array and a Fourier transform lens, and between a dispersion grating and the lens equal to the focal length of the lens. The optical path lengths reduce losses due to angular acceptance mismatch in the multiplexer. Close orientation of the fiber array about the optical axis and the use of a holographic dispersion grating reduces other losses in the system. Multi-exposure holographic dispersion gratings enable the multiplexer/demultiplexer for extremely broad-band simultaneous transmission and reflection operation. Individual Bragg plane sets recorded in the grating are dedicated to and operate efficiently on discrete wavelength ranges.

The light from the reflector is directly incident upon the incident end. The systems and methods provide advantages in that the light from the LCD is bright and homogenous.

High Channel Density, Broad Bandwidth Wavelength Division Multiplexer With Highly Non-Uniform Bragg-Littrow Holographic Grating

View page
US Patent:
50261312, Jun 25, 1991
Filed:
Nov 13, 1989
Appl. No.:
7/435608
Inventors:
Tomasz P. Jannson - Torrance CA
Joanna L. Jannson - Torrance CA
Christopher C. Rich - San Pedro CA
Behzad Moslehi - Redondo Beach CA
Assignee:
Physical Optics Corporation - Torrance CA
International Classification:
G02B 518
US Classification:
350 37
Abstract:
A wavelength division multiplexer/demultiplexer having optical path lengths between a fiber array and a Fourier transform lens, and between a dispersion grating and the lens equal to the focal length of the lens. The equal optical path lengths reduce losses due to angular acceptance mismatch in the multiplexer. Close orientation of the fiber array about the optical axis and the use of a holographic dispersion grating reduces other losses in the system. Multi-exposure holographic dispersion gratings enable the multiplexer/demultiplexer for extremely broad-band simultaneous transmission and reflection operation. Individual Bragg plane sets recorded in the grating are dedicated to and operate efficiently on discrete wavelength ranges. A volume Bragg vertically non-uniform holographic grating enables operation of the multiplexer or other devices that act on light waves according to wavelength over nearly the full usable 0. 8-1. 3. mu. m wavelength range.

Holographic Lippmann-Bragg Filter In A Spectroscopic System

View page
US Patent:
51536706, Oct 6, 1992
Filed:
Jan 12, 1990
Appl. No.:
7/464116
Inventors:
Tomasz P. Jannson - Torrance CA
Joanna L. Jannson - Torrance CA
Michael T. Feeney - Hacienda Heights CA
Assignee:
Physical Optics Corporation - Torrance CA
International Classification:
G01J 344
G02B 532
US Classification:
356301
Abstract:
A holographic filter comprises a volume hologram recorded with Bragg surfaces for use in spectroscopic and spectral splitting applications. The Bragg planes in the holographic filter can be recorded to satisfy virtually any design constraint imposed upon the filter such as Raman, Lippmann, non-Snellian (slanted), curved, and multiplexed spectral filters. The holographic filter achieves maximal reduction of secondary maxima and sidelobes and obtains large wavelength selectivities, and varied grating constants.
