360 DEG View camera

摘要

A 360 DEG 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.
