46671790, May 19, 1987

Filed:

Mar 7, 1985

Appl. No.:

6/709638

Inventors:

Simon M. Law - Torrance CA
Thierry L. Watteyne - Rancho Palos Verdes CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

H03M 168

US Classification:

340347DA

Abstract:

A weighted capacitor digital to analog converter is disclosed which requires only one stage and one conversion step. By the use of two reference voltages and two groups of capacitors in parallel, various capacitors in these groups can be selectively switched from the reference voltages to ground potential in response to input binary digit signals thereby presenting a predetermined amount of voltage to the output amplifier depending upon the number and particular combination of capacitors switched or non-switched to ground.

International Classification:

G02B 21/00

Abstract:

A compressive imaging system includes an illumination system arranged to illuminate an object of interest with illumination light, and a detection system configured to detect at least a portion of the illumination light after being at least one of reflected from, scattered from, or transmitted through the object of interest or to detect fluorescent light from the object of interest and to provide an imaging signal. The compressive imaging system further includes an image processing system configured to communicate with the detection system to receive the imaging signal. The illumination light from the illumination system comprises a plurality of light pulses such that each light pulse has a preselected spectrum that is distinguishable from spectra of all other pulses. The image processing system is configured to form an image of the object of interest using information concerning the preselected spectra of the plurality of light pulses.
