ABSTRACT:
A method and apparatus for scanning two fields of view by optical/mechanical means, in two scanning directions which are disposed essentially at right-angles to one another, and for simultaneously displaying these fields of view, this method utilizing two optical/mechanical scanners, one of the scanning processes, in the line direction, being performed rapidly, and the other scanning process, in the vertical direction, being performed slowly, using only one detector or one detector array, wherein the line-scanning efficiency does not exceed 50% for both fields of view and there is a 180.degree. phase shift between the line scanning processes respectively applied to the two fields of view.
