摘要：
An optical probe system having a probe with an optical guide (G) having a distal end. The optical guide (G) is mounted inside a housing (H) so that the distal end is displaceable with respect to the housing (H). A set of actuators (A), e.g. electromagnetic drive coils, can displace the distal end by application of a drive signal (Vx, Vy). A control unit (CU) generates the drive signal (Vx, Vy) so as to provide a scanning frequency which varies according to an amplitude of the drive signal (Vx, Vy). With such probe system it is possible to scan a field of view with a scanning frequency that varies with the scanning radius. Taking into account the maximum allowable drive current, it is possible to increase scanning speed compared to scanning at the mechanical resonance frequency of the optical system, since small radii can be scanned at a high scanning frequency.
