Inexpensive battery-operated motors can be used for a variety of safe, fast, laser beam-steering and modulation activities, a number of which have been developed as part of the Laser Applications in Science Education (LASE) Project at San Jose State University.
Those described here will be a) a laser stroboscope using a spinning slotted disc, b) a circular scanning system using a tilted rotating mirror, for bar code reading, investigating the focussing properties of lenses, lens aberrations, and beam profiles, and c) a rotating polarizing sheet.
