ABSTRACT:
A holographic system for recording movements of body surfaces of a patient characterized by a source of coherent light projecting on the body surface to create an object wave and having a portion of the light as a reference wave, a film carrier for photographic film disposed to simultaneously record the object and reference waves as a hologram and switching devices which are activated by a transmitter device sensing cardiac activity for double pulse switching of the source at predetermined intervals so that the two separate holograms of the body surface are recorded with each hologram being at a different time interval of the movement of the body. The present invention enables the two holograms which are recorded on the film to be recorded at given points in a cardiac activity of the patient such as given points of the EKG cycle of the patient.
