Scanning mirrors have a wide variety of applications, all of which involve moving the mirror from one position to another, either cyclically or quasi-statically. Resonant scanning — moving the mirror sinusoidally at its resonant frequency — is useful in such applications as line-scanning for barcode readers, raster-scanned video displays, and laser printers. Steady-state beam steering — moving the mirror from one static position to another — is useful for such applications as fiber-optic components (optical switches, variable-optical attenuators, et cetera) and point-to-point optical-communication systems.
