Scanning performance defines mainly capabilities of laser display systems. The use of mirror galvanometers provides simple reliable and inexpensive devices for the laser beam scanning. Maximal deflections of mirrors and a frequency band depend on both the mirrors' dimensions and the magnetic system's features. On the other hand the mirrors' areas, their deflections, and frequency band determine the laser beam image performance. An amplitude response of the galvanometers under various mirror designs and different kinds of magnetic materials has been studied over the frequency range from 0 to 6000 Hz and angles of deflection to +/- 7 degrees. Our results demonstrated a small cross-section laser beam's successful control over a frequency range to 3500 Hz without any feedback. The investigation allowed us to develop improved wideband scanners with light-weight mirrors and high residual magnetization magnetic systems.
