Method of infrared imaging

摘要

The method herein images an object repeatedly moving about an axis. The method uses signals to track the object's position with respect to the axis while a camera views the object. A reflection is cast from the object toward the camera in such a way that the camera scans both the reflection and the object. The camera outputs representations of video lines, which depict parts of the object and the reflection. These video lines have known positions relative to a reference plane, which passes through the image plane of the camera. Certain of the video lines are selected. The selected lines come from a chosen position relative to the reference plane and occur within a chosen time of the position signals. The selected video lines are arrayed according to their particular position signals and are used to compile a planar composite image representing the object's outer periphery. The composite image is conformed to a shape resembling the periphery, thereby creating a three dimensional representation of the object.
