How it Works
The laser oscilliscope uses three core components: a laser, stepper motor, and galvanometer. Waveforms are created by bouncing the laser light off two mirrors attached to each motor, one for x-axis (side to side) scanning and the other for y-axis (up, down) scanning. The laser locust thus gains a dimension after contact with each mirror and the output is a projection of a two dimensional waveform.
1) Laser beam reflects off galvanometer mirror, creating the vertical dimension of the projection.
2) Laser beam is swept horizontally by a 16-sided spinning mirror mounted to the stepper motor.
3) Final projection is displayed on surface, tracking the fundamental frequency and amplitude of the audio input
