Abstract:
A two-motor reflection system with a hologram, comprising:light source means for generating a light beam;first reflector means, connected to be driven by a first motor electrically connected to a first control circuit, for reflecting the light beam generated by the light source means at a first angle and including first balance means for adjusting the first angle and mounted on the first motor for changing the first angle by changing the rotating speed of the first motor, the rotating speed of said first motor being controlled by sound;second reflector means, connected to be driven by a second motor electrically connected to a second control circuit, for reflecting the light beam reflected by the first reflector means at a second angle and including second balance means for adjusting the second angle and mounted on the second motor for changing the second angle by changing the rotating speed of the second motor, the rotating speed of said second motor being controlled by sound; andholographic means, mounted in the optical path of the light beam from the second reflector means, for diffracting the light beam from the second reflector means to enhance extent and variety of scanning patterns.
