Abstract
A holographic optics orientation assembly for a holographic recording unit having a laser holographic recording system for recording holograms of subjects situated within a holographic recording field of the recording system. The orientation assembly is adjustable to adjust or shift the recording field without moving the entire recording unit and thereby permit pointing or aiming of the recording system at a selected subject without moving the entire unit.
Claims9
A holographic optics orientation device comprising:
- a pivotal assembly having a pivot axis and including first optical means for receiving a holographic scene beam along said axis and directing the beam along a path transverse to said axis to provide an illuminated holographic recording field in front of said assembly, means for positioning a holographic recording medium to receive reflected scene beam light from a subject in said field, and second optical means for receiving a holographic reference beam along said axis and directing the latter beam toward said medium to illuminate the latter, and pivot means for mounting said assembly for rotation about said axis.
