Appl. No.:

13/242677

Inventors:

CHRISTOPHER D. STARTA - PITTSBURGH PA, US
ROBERT E. UBER - PITTSBURGH PA, US
THOMAS TRAUTZSCH - CRANBERRY TOWNSHIP PA, US
FREDERICK J. SCHULER - WEXFORD PA, US

International Classification:

G01J 5/08
G01N 21/01

US Classification:

2503417, 250353

Abstract:

A closed path infrared sensor includes an enclosure, a first energy source within the enclosure, at least a second energy source within the enclosure, at least one detector system within the enclosure and a mirror system external to the enclosure and spaced from the enclosure. The mirror system reflects energy from the first energy source to the at least one detector system via a first analytical path and reflects energy from the second energy source to the at least one detector system via a second analytical path. Each of the first analytical path and the second analytical path are less than two feet in length.
