Appl. No.:

10/419797

Inventors:

Benjamin R. Neff - Fort Wayne IN, US
Jeff D. Pruitt - Fort Wayne IN, US
Matthew L. Gypson - Fort Wayne IN, US
Michael E. Dobbs - Fort Wayne IN, US

Assignee:

ITT Manufacturing Enterprises, Inc. - Wilmington DE

International Classification:

H01J040/14
H01J005/16

US Classification:

250226, 250214 A, 250574

Abstract:

A system for sensing a characteristic of a sample may include a tunable source configured to emit optical radiation that varies over a wavelength range at a first frequency and a reference source configured to emit optical radiation that varies in amplitude at a second frequency. A science detector may be configured to detect the optical radiation from the tunable source and the reference source after interaction with the sample and generate a science signal. A number of lock-in amplifiers may be respectively configured to generate components of the science signal that are present at the first and second frequencies. A processor may be configured to determine a characteristic of the sample based on the components of the science signal that are present at the first and second frequencies.

US Classification:

250226, 250214 A, 250574

Abstract:

A system for sensing a characteristic of a sample may include a tunable source configured to emit optical radiation that varies over a wavelength range at a sweep frequency and a reference source configured to emit optical radiation at a reference wavelength. A first modulator may be configured to modulate the first optical radiation at a first frequency, and a second modulator may be configured to modulate the second optical radiation at a second frequency that is different from the first frequency and the sweep frequency. A science detector may be configured to detect the optical radiation from the first modulator and the second modulator after interaction with the sample and generate a science signal. A number of lock-in amplifiers may be respectively configured to generate components of the science signal that are present at the first and second frequencies. A processor may be configured to determine a characteristic of the sample based on the components of the science signal that are present at the first and second frequencies.

Assignee:

ITT Manufacturing Enterprises, Inc. - Wilmington DE

International Classification:

G01J 4/00

US Classification:

356364

Abstract:

Remotely sensing a target may include generating a first beam of optical radiation that is modulated at a first frequency and polarized at a first polarization. A second beam of optical radiation that is modulated at a second frequency and polarized at a second polarization may also be generated. The first and second beams of optical radiation may be transmitted to the target. Radiation at the first polarization and radiation at the second polarization may be detected from the target using a phase sensitive technique and the first and second frequencies.

Assignee:

ITT Manufacturing Enterprises Inc. - Wilmington DE

International Classification:

G01C 3/08

US Classification:

356 401, 356 507, 356 28, 35613903, 244 316, 2502032

Abstract:

A method of tracking a target includes: (a) receiving energy from the target at a plurality of spatial orientations; (b) processing the received energy; (c) evaluating a penalty function at each of the plurality of spatial orientations; (d) selecting a new spatial orientation based on the evaluation; and (e) orienting a receiver to receive energy from the target at the new spatial orientation.

US Classification:

398 25, 398 27, 398 26, 356432, 250343

Abstract:

A system for measuring properties of a medium includes an electromagnetic generator for forming a CW carrier, a digital encoder for forming a digital message, and a modulator for modulating the CW carrier with the digital message to form a digitally modulated CW carrier. The medium provides a channel for propagating the digitally modulated CW carrier. The system further includes a receiver configured to receive the propagated, digitally modulated CW carrier, and a processor for measuring at least one property of the medium. The medium may be disposed within a gaseous atmosphere, a body of water, or a cell of a laboratory.
