ESSENTIALLY NEW LARGE-ANGLE HIGH DEFLECTING FREQUENCY LASER BEAM SCANNING SYSTEM (LALS)We’d like to present two inventions “Method of large-angle high deflecting frequency laser beam scanning system for transmission and receiving video- and other images and device for its realization” and “Method of creation of 3D color virtual video image and device for creation of effect of virtual reality for user”, which can be applied to laser video and TV projection, creation of 3D color virtual video image with effect of virtual reality for user, display technologies, laser copying, scanning and printing systems, laser security, night vision and navigation systems, and to other laser systems. More detailed information is presented on EXAMPLES OF PRACTICAL APPLICATION OF LALS-BASED DEVICES LALS MAIN TECHNICAL ADVANTAGES. Changeable scan angle: 30–180° (depends on the laser beam deflecting frequency), resonant (deflecting) frequency: 0.5 – 16.0 kHz and more, small dimensions and weight (see below), simple and low cost architecture, long lifetime – not less than 100 000 hours. SHORT DESCRIPTION OF THE INVENTION. Method and device of LALS are realized in result of resonant generation of transverse oscillations of two oscillating plates (resonators) with different densities, connected in series. The second plate (resonator), which has lower density and laser reflecting surface, being in the mode of resonant oscillation, deflects falling laser beam in accordance with parameters, shown below. LALS can be applied as to line and to frame laser deflection.
