A new type of rotating-mirror framing-camera optical system is propose
d. A study is reported of the feasibility of the use of an aspherical
mirror, with its surface in the shape of a prolate ellipsoid of revolu
tion, in the scanning system of the camera. Starting from the aberrati
on minimization conditions, the optimization of the parameters of the
optical system is carried out. An aspherical mirror of this kind perfo
rms not only the scanning function, but also acts as a condenser, thus
greatly simplifying construction of the camera.
