US Patent:

7369483, May 6, 2008

Filed:

Jan 21, 2005

Appl. No.:

10/588066

Inventors:

W. Dennis Slafer - Arlington MA, US
Matthew White - Cohasset MA, US
Milford Kime - Cambridge MA, US
Timothy Frey - Hudson MA, US

Assignee:

MicroContinuum, Inc. - Cambridge MA

International Classification:

G11B 7/24

US Classification:

3692754, 369283

Abstract:

A pre-formatted optical data storage tape () including an elongated linear polymer layer having at least one pattern of optically readable embossments () on at least one surface of the polymer layer, and an optical recording layer covering the pattern of optically readable embossments () of the elongated linear polymer layer, wherein the optical recording layer is adapted such that recorded marks () may be made in the recording layer by directing a focused source of energy into the recording layer.

US Patent:

41711599, Oct 16, 1979

Filed:

Jul 14, 1977

Appl. No.:

5/815879

Inventors:

Matthew B. White - Cohasset MA

International Classification:

G01B 902

US Classification:

356349

Abstract:

An optical homodyne microscope is disclosed which detects phase modulation of the optical radiation that is reflected from an object under study which is in a state of periodic motion. The dimensions of the object may be smaller than the optical wavelength with this technique. By analyzing the resultant phase modulation spectrum, information concerning the shape of the object can be obtained.

Filed:

Sep 19, 1974

Appl. No.:

5/507646

Inventors:

Matthew B. White - Cohasset MA
Fred W. Quelle - Cohasset MA

International Classification:

H01S 310
H01S 3101

US Classification:

331 945K

Abstract:

A two-dimensional dye laser scanning system is provided wherein a dye laser having a controlled output wavelength is combined with a diffractive beam-bending device to produce a near infrared or visible laser beam that can be directed to scan in two orthogonal planes at 100 MHZ rates.

US Patent:

Filed:

Nov 4, 1976

Appl. No.:

5/738989

Inventors:

Matthew B. White - Cohasset MA

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G01C 308

US Classification:

356 5

Abstract:

Systems which utilize an optical signal to carry information and employ a ree-wave heterodyne detector of the type having a cubic response do not require a local optical signal source in the receiving apparatus since the optical signal as generated provides two optical signal components for the detector's operation. The third signal is supplied by a local microwave oscillator. A high resolution optical wave ranging system having an improved field-of-view is disclosed which uses such a composite signal in conjunction with a pair of three-wave heterodyne detectors.

Filed:

Appl. No.:

5/460245

Inventors:

Matthew B. White - Cohasset MA

International Classification:

H01S 310

US Classification:

331 945M

Abstract:

An arrangement for frequency modulating a laser beam utilizes an optical prism which is disposed within the laser cavity such that the beam continuously experiences total internal reflection from one face thereof as an optical element having an index of refraction which is less than that of the prism is displaced so as to come in contact with this face and/or move variable distances therefrom. The external optical path of the beam, which exists beyond this face during total internal reflection is, thus, changed. This corrresponds to an effective change in the dimensions of the laser cavity and an appropriate shift in the frequency of the laser output beam. Amplitude modulation of the beam can also be achieved by placing the above components outside of the cavity and changing the direction of polarization of the beam entering the optical prism.
