Abstract :
We present a viewer-interactive laser scanning display (LSD) that could control the projected images by optically detecting an object in the projected ray. A piezoelectric PZT scanner is used as a spatial modulator to construct the full-color HD-class LSD optics and also to develop the triangulation laser range finder that is sensitive in a 20 to 60 cm distance. Distance to screen was successfully measured to give feedback to the projected image. We also demonstrate page-turning by using the viewer´s gesture.
