US Patent:

7174198, Feb 6, 2007

Filed:

Dec 23, 2003

Appl. No.:

10/745092

Inventors:

Igor Trofimov - Long Valley NJ, US
Stephen A. Lyon - Cranbury NJ, US

International Classification:

A61B 5/00

US Classification:

600322, 600316

Abstract:

A system and method for determining the concentration of analytes of interest in complex matrices is provided. According to one aspect of the present invention, near-infrared analytical radiation is generally directed onto a portion of a specimen containing the analyte of interest. A wavelength of the analytical radiation is scanned over the specimen over a broad range of frequencies and over a short duration of diagnostic time. A spectrum of radiation is transmitted through, reflected from or scattered from the specimen and collected by a detector. The concentration of the analyte of interest in the specimen is determined by the radiation collected by the detector.

Appl. No.:

11/622704

Inventors:

Igor Trofimov - Long Valley NJ, US
Stephen A. Lyon - Plainsboro NJ, US

International Classification:

G01J 5/02
H01L 27/14
G01J 5/20
H01L 31/00

US Classification:

25033911, 2503418, 2503384

Abstract:

The present invention relates to a photosensitive diagnostic device configured to project an optical signal, capture reflected portions of the optical signal, and convert the captured portions of the optical signal into an electrical signal indicative of characteristics of a sample analyzed by the device. In accordance with one embodiment, a photosensitive diagnostic device comprises an illumination source and a detector. The illumination source comprises an output face configured to project an optical signal characterized by at least one diagnostic frequency. The detector comprises a photosensitive input face configured to capture reflected portions of the optical signal. The photosensitive input face of the detector is further configured to convert the captured portions of the optical signal into one or more electrical signals at least partially representing a degree of change in the diagnostic frequency of the optical signal. The output face of the illumination source and the photosensitive input face of the detector lie in a substantially common plane. The present invention further relates to a diagnostic system comprising an embodiment of the photosensitive diagnostic device herein described.
