Far field imaging

Patent ·
OSTI ID:5333112
For imaging distant radiation sources, a collimator is rotated about its own axis while that axis moves about a fixed axis pointing toward the overall field of view of the collimator. Radiation from the source will be transmitted through the collimator during each of its revolutions about its axis. The angular position of the collimator about its axis, and the angular position of the collimator axis about the fixed axis, at the time of each such transmission, define a response plane. Computerized data reduction is used to find the intersection of the response planes, which will be a line pointing precisely at the source. For multiple sources, there will be a corresponding number of intersections.
