SCANNING APPARATUS AND METHOD

摘要

An optical fibre (4) with a light-receiving end (18) is mechanically driven so that its end moves to scan an image, the optical fibre being driven to oscillate substantially at or near the natural resonant frequency of the fibre. The movement of the optical fibre is driven by at least one bimorph ceramic oscillator (20, 22). The light-receiving end of the fibre traces a scan path in the form of a time-varying Lissajous pattern.
