Self-aligned vertical comdrive actuators for optical scanning micromirrors

A film mount and mask for a panoramic stereoscopic camera in which processed film strip has stereoscopic pairs of film frames cut and mounted in a holder providing a mask for each frame and means comprising a boss provided for each film frame in the mount to register with a notch in the film for positioning purposes, and to prevent the film frame from moving towards either extremity when heated in a projector, each film frame being held in a cylindrical plane by means of a mask, with means formed into the mount to accept either clips, or plastic feet in the case of a plastic mask, to secure the film frames tight against the curved focal plane formed in the mount, said plane being identical as to focal radius with the curved film bed in the panoramic stereoscopic camera in which the film was exposed.
