Information display method and system
Abstract
Abstract A LARGE SCREEN REAL TIME LASER DISPLAY SYSTEM IS DESCRIBED. A MAGNETIC DRUM AND A MULTI-FACETED SCANNING MIRROR ARE MOUNTED ON A COMMON SHAFT AND ROTATED AT A HIGH RATE OF SPEED. DIGITAL DATA DESCRIPTIVE OF THE IMAGE TO BE DISPLAYED IS STORED ON A PLURALITY OF TRACKS ON THE DRUM AND UPDATED AS REQUIRED BY A DIGITAL COMPUTER. THE DATA IS CONTINUALLY READ FROM THE DRUM AND RED, BLUE AND GREEN LASER BEAMS ARE SPLIT INTO A PLURALITY OF BEAMS EACH OF WHICH IS MODULATED IN ACCORDANCE WITH THE STORED INFORMATION. THE MODULATED BEAMS ARE THEN RECOMBINED AND DIRECTED ONTO THE MULTI-FACETED MIRROR WHICH SCANS THE BEAMS OVER A SCREEN TO PRODUCE A FULL COLOR IMAGE. THE LIGHT MODULATORS ARE ACOUSTIC MODULATOR BODIES IN WHICH STRESS WAVES HAVING A PLURALITY OF SEPARATE WAVELENGTHS, EACH INDIVIDUALLY AMPLITUDE MODULATED, ARE ESTABLISHED. THIS PRODUCES A PLURALITY OF INDIVIDUALLY AMPLITUDE MODULATED LIGHT BEAMS. D R A W I N G
