Filed:

Jun 19, 2003

Appl. No.:

10/601893

Inventors:

Eric Hillenbrand - Evansville IN, US
Mark Dombrowski - Escondido CA, US
Jim Lorenz - Escondido CA, US
Eric Ford - LaCanada CA, US

Assignee:

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

International Classification:

H01L025/00

US Classification:

250332, 250330, 25033901

Abstract:

A two band imaging system having two focal plane array detectors, a beam splitter, and an enclosure. The beam splitter disposed within the system at an angle to the optical axis such that light entering the system is split and is simultaneously directed to each of the two focal plane array detectors. The two focal plane array detectors and beam splitter are disposed within the enclosure.

Inventors:

Mark Dombrowski - Escondido CA, US
Brian Catanzaro - San Diego CA, US

Assignee:

Surface Optics Corporation - San Diego CA

International Classification:

G01N 21/25

US Classification:

356419

Abstract:

A hyperspectral imager that achieves accurate spectral and spatial resolution by using a micro-lens array as a series of field lenses, with each lens distributing a point in the image scene received through an objective lens across an area of a detector array forming a hyperspectral detector super-pixel. Each sub-pixel within a super-pixel has a bandpass or other type filter to pass a different band of the image spectrum. The micro-lens spatially corrects the focused image point to project the same image scene point onto all sub-pixels within a super-pixel. A color separator can be used to split the image into sub-bands, with each sub-band image projected onto a different spatially corrected detector array. A shaped limiting aperture can be used to isolate the image scene point within each super-pixels and minimize energy coupling to adjacent super-pixels.

Abstract:

A hyperspectral imager that achieves accurate spectral and spatial resolution by using a micro-lens array as a series of field lenses, with each lens distributing a point in the image scene received through an objective lens across an area of a detector array forming a hyperspectral detector super-pixel. Spectral filtering is performed by a spectral filter array positioned at the objective lens so that each sub-pixel within a super-pixel receives light that has been filtered by a bandpass or other type filter and is responsive to a different band of the image spectrum. The micro-lens spatially corrects the focused image point to project the same image scene point onto all sub-pixels within a super-pixel.

Appl. No.:

13/850832

Inventors:

Jon Morris - Baton Rouge LA, US
Mark Dombrowski - San Diego CA, US

International Classification:

H04N 5/33

US Classification:

348135

Abstract:

The multi-spectral imaging system for real-time measurement of combustion efficiency of an industrial flare is provided. The system includes four spectral bands, one for a hydrocarbon group (fuel), one for carbon dioxide (CO), product of complete combustion), one for carbon monoxide (CO, product of partially completed combustion), and one for background reference. More spectral bands can be added to measure combustion efficiency of specific compounds or enhance the background reference adjustment. The analysis apparatus includes a machine readable storage medium, which provides instructions that cause the analysis apparatus to perform operations to obtain the combustion efficiency of the flare. The operations includes acquiring at least three spatially and temporally synchronized intensities from an imaging unit capturing images of the flare, and producing the combustion efficiency of the flare from said at least three intensities, and absorption coefficients of materials contained in the flare.

Appl. No.:

Inventors:

Mark Dombrowski - Escondido CA
James Lorenz - Escondido CA

Assignee:

Surface Optics Corporation - San Diego CA

International Classification:

G01J 328

US Classification:

250330

Abstract:

A spectroradiometer images a scene as a repeating sequence of spectral images, each of which spectral images depicts the scene at a preselected wavelength. In a preferred embodiment, the image is of size 256 by 192 pixels, and the sequence repetition rate is about 20-30 cycles per second. Full spectral analysis on the resulting sequences is performed substantially in real time. The spectroradiometer includes a light collector with a lens, a circularly variable spectral filter, and an optical gate which gates the output of the filter to a detector array which outputs the sequence of electronic spectral images. These images are corrected for systematic errors and calibrated, and correlated with a preselected spectral response function. The image may be further post-processed and displayed in video format or used otherwise.
