Laser galvo mirrors: perfect instrument for the demonstration of Lissajous figures
Original language description
A pair of galvo mirrors reflecting light from a laser pointer is suggested for use as a school demonstration of Lissajous figures. The device is small, cheap and easy to assemble. Combined with a two-channel waveform generator, a full spectrum of excellently stable Lissajous figures can be generated (concerning frequency ratio, amplitude ratio and initial phase angle difference). The operation at frequencies faster than the vision persistence allows us to draw the figures on a normal projection screen or on a wall. When operated with a violet laser pointer and a thermoluminescent foil, the frequencies can be decreased and the advance in figure drawing can be followed. The memory effect of the thermoluminescent foil also enables us to record and observe several Lissajous figures simultaneously.
