1. A method for producing a holographic image of an object, the method comprising:
dividing an input beam into a first beam, a second beam and a third beam using beam splitters;
steering the first beam, the second beam and the third beam into desired directions;
keeping the third beam unexpanded and making the third beam incident normally on a hologram recording plate; and
generating an object beam and a reference beam; and
wherein a holographic image is produced in a compact and vibration resistant manner by passing light scattered from the object through at least one negative lens to form a reduced image of the object and at least one positive lens that gathers more light.
