Abstract
A packageable system employs principles 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.
