Abstract:

A packageable system employs priciples of Doppler holography on near-field objects to produce images from which photographs, transparencies or video reproductions can be made with simultaneous improvements in depth of field, foreground-backregion exposure ratio, and resolution where degraded by the object medium. The apparatus consists of two units a main unit containing a laser and optics, and an external platform that rotates at an appropriate angular velocity, through a very small arc, during image recording of an object on the platform.
