摘要： In an optical transmitting and receiving apparatus. an light transmitting and receiving unit includes a light emitting element, a light transmitting lens, a light receiving lens, and a photosensitive element. The light emitting element outputs light. The light outputted from the light emitting element passes through the light transmitting lens before leaving the light transmitting and receiving unit as outgoing light. The light receiving lens concentrates incoming light on the photosensitive element. A first support member is operative for supporting the light transmitting and receiving unit, and for allowing the light transmitting and receiving unit to rotate about a first axis. A first rotary mechanism connected to the light transmitting and receiving unit and the first support member is operative for rotating the light transmitting and receiving unit about the first axis. A second support member is operative for supporting the light transmitting and receiving unit on a cantilever basis, and for allowing the light transmitting and receiving unit to rotate about a second axis perpendicular to the first axis. A second rotary mechanism connected to the light transmitting and receiving unit and the second support member is operative for rotating the light transmitting and receiving unit about the second axis.

摘要： In a color image display apparatus, light beams intensity modulated by a green color image signal are deflected by an ocillating mirror, and then focused on a photo-conductive layer (PCL) member of a light-written type spacial light modulation element (SLM) through two focusing lenses for light write operation. Light beams intensity modulated by a time-axis compressed time-divisional image signal of two remaining colors (red and blue) are deflected by another mirror oscillated simultaneously with the ocillating mirror, and then focused on a PCL member of a SLM of the same type through two focusing lenses for light write operation. A read light beam is resolved into the light of the green wave length band and the lights of red and blue wave length bands, respectively, and then given to the SLMs, respectively for light read operation. The two read light beams reflected by the SLMs are synthesizing, and then projected on a screen through a common projection lens.
