DEFINITION

Classification: 359/292

Light control surface forms image on projected light beam:

(under subclass 291) Subject matter wherein the contours of a light control surface are modified in accordance with a control signal so as to impart image or picture information to the contour of the control surface which is then transferred to a light beam projected on or through the control surface.
