ABSTRACT:
In order to scan a rather large field of view quickly, the field of view is imaged, by an imaging optical system, in the plane of a detector having a substantially linear array of detector elements. The path of rays comprises a rotating optically refracting wedge for causing a nutating movement of the image and, coaxial therewith a rotating Dove prism for causing rotation of the image. The wedge and the Dove prism rotate at different rotary speeds.
