ABSTRACT:
A radiation scanning system comprises a detector, a transfer lens forming a real image of the detector, a rotary scanning means interposed between the transfer lens and the detector image in such a way that as the rotary scanning means is rotated the detector image moves in a circular locus, a concave substantially-spherical mirror concentrically disposed with respect to the detector locus, said locus being at the focal surface of the mirror so that for different rotational positions of the rotary scanning means differently directed parallel bundles of rays emanate from the mirror all intersecting at a pupil, and a second scanning means located at said pupil. The two scanning means provide orthogonal line and frame scans.
