Abstract
A scanning mechanism for an optical probe having an optical head and an optical transmitter for transmitting light from a light source to the optical head, the scanning mechanism comprising a resilient member coupled to the optical transmitter, a fluid supply for providing a fluid to the head, and an exit path for the fluid from the head that has a fluid entry. The resilient member is located at the fluid entry so that fluid flow into the fluid entry passes over a portion of the resilient member and creates a pressure difference across the resilient member such that the resilient member is urged into the fluid entry thereby reducing the fluid flow and reducing the pressure difference, whereby the resilient member and therefore the fiber can be induced to oscillate.
