ABSTRACT:
A shutterless pulse laser holographic recording system comprises a holographic image recording medium, a high pass filter positioned between the medium and the object whose image is to be recorded, a white light source to illuminate the object, and a low pass filter between the white light source and the object. The filtering arrangement allows illumination of the object with white light before and during the holographic recording event but prevents the illumination light from reaching the medium. A method for recording is also described.
