Appl. No.:

7/837425

Inventors:

Alex Toh - San Diego CA
James J. Lorenz - San Diego CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

US Classification:

D14150

US Patent:

54245435, Jun 13, 1995

Filed:

Apr 19, 1993

Appl. No.:

8/049035

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.
