Abstract

Holographic scanners/deflectors have been used to replace common mirrors with very limited success. When an application requires more than a simple polygon or when two or three functions can be performed by a single holographic element then the holographic approach appears more attractive and historically has been more successful. This paper reveiws 3 special purpose device designs with emphasis on the hologram design considerations, fabrication details and performance.
