High-speed framing camera with an ellipsoidal scanner

A new type of rotating-mirror framing-camera optical system is proposed. 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 revolution, in the scanning system of the camera. Starting from the aberration minimization conditions, the optimization of the parameters of the optical system is carried out. An aspherical mirror of this kind performs not only the scanning function, but also acts as a condenser, thus greatly simplifying construction of the camera.
