    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.

    摘要: The present invention relates to an optical probe (1) with an optical guide (2), e.g. an optical fibre, and a lens system (6) rigidly coupled to an end portion (2a) of the optical guide. The probe has a housing (3) with a cavity for the optical guide, the housing having at its distal end a transparent window (4), the window having an insignificant optical power as compared to the optical power of the said lens system (6). Actuation means (8) displaces the 5 lens system so as to enable optical scanning of a region of interest (ROI). The invention is particularly suited for miniature applications e.g. for in-vivo medical application. By attaching the lens system (6) to the optical guide (2) via the mount (7), the field of view (FOV) of the optical probe (1) may be determined directly by the transverse stroke of the optical fibre (2). Hence only a relatively small stroke is required. The field of view is thus 10 effectively no longer limited by the transverse stroke. The optical probe is especially advantageous for non-linear optical imaging where the optical guide may be an optical fibre with a relatively low exit numerical aperture.

    摘要: Fluid lens system, e.g. for medical imaging or medical treatment, with a container enclosing a fluid arranged to refract incoming waves. A pressure release mechanism is in contact with the fluid so as to compensate changes in its volume due to thermal variations, e.g. during high temperature medical cleaning. This pressure release mechanism is positioned within a pathway of incoming waves. In preferred embodiments a fluid container connected via a tube to the fluid as a reservoir, is arranged within or outside the container, e.g. beyond an image sensor. Alternatively, an easily compressible body, e.g. a small closed metal bellows enclosing a gas, is positioned inside the fluid to absorb volume changes by compression. In both embodiments, the pressure release elements are preferably positioned in a peripheral part of the pathway of incoming waves to not affect performance of the lens. In another aspect, a fluid lens includes a container with an inner container part that fits inside an outer container part, wherein the inner container part is in rigid connection to at least a one boundary arranged for penetration of incoming waves. The pressure release mechanism is positioned within the outer container part, and it is in contact with the fluid so as to compensate changes in volume of the fluid due to thermal variations. In one embodiment the inner and outer container parts are arranged for relative one-dimensional movement and fluid tight interconnected. In another embodiment, a fluid filled cavity is formed between the inner and outer container parts, and this cavity houses a compressible body. The lens systems are suited for applications such as medical endoscopes, catheters and needles, optically as well as acoustically based.
