ABSTRACT:
A holographic spinner reconstructs a light spot to rapidly scan a narrow line on a suitable "write" surface to generate an image. The spinner is flexibly mounted to assume a high degree of uniformity in its perpendicularity relative to the axis of spin to minimize spot wobble. Alternatively, the spinner is itself a flexible material or floppy disk.
Method of mounting the disk on a shaft using a setting compound during spinner rotation is also disclosed.
