US Patent:

44286562, Jan 31, 1984

Filed:

Aug 26, 1982

Appl. No.:

6/411941

Inventors:

John R. Gebhart - Enfield CT
Francis X. Ledoux - Springfield MA

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

G03B 3700

US Classification:

354 80

Abstract:

A 360. degree. view camera for taking photographs of the interior of a cylinder or cone includes a rotating mirror disposed 45. degree. about the axis of rotation which is in coincidence with the cylinder or cones centerline that is parallel to a rotation mirror mounted in the film magazine. A slit in the film magazine exposes a stationary flat sheet film wound around a cylinder to a lens that is in line of sight with the rotating mirrors. Adjustment means are provided to eliminate distortions of the specimen being photographed.

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

G01J 560

US Classification:

356 45

Abstract:

Apparatus for making temperature measurements where reflected energy has an adverse effect on the measured target temperature is disclosed. A pair of detectors see the same target but with the use of at least one filter so that the wavelength interval of one is contained within the other. From the output, calculations are made to correct for the errors due to the reflected energy.

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

G03B 3700

US Classification:

354 80

Abstract:

A 360. degree. view camera for photographing the surface of a cylindrical or conical surface includes a magazine housing sheet film wound on a rotating cylinder exposed to a fixed lens through a fixed slit aligned with a specimen to be photographed where the specimen is rotated in a predetermined relationship with the rotation of the film. In another embodiment a fiber optic bundle transmits the view from a fixed mirror to the lens. In each of these embodiments means are provided for minimizing the distortions in the negative so that the film can be utilized for an automated temperature paint analysis by digitizing the film and processing the information through a computer to calculate the temperature profile of the cylinder after being subjected to a heat environment.
