    摘要: The invention relates to an optical image probe(20) for particularly suited for miniature application e.g. in-vivo. A fluid lens(5) is positioned a housing (19),the fluid lens having a changeable optical power. An image collector (40) is positioned within the housing, the collector being arranged on an optical path of the fluid lens, the collector being displaceable along the said optical path by an actuator (42, 70, 80, 90) in various ways. It is highly advantageous in obtaining a compact optical image probe and which simultaneously has a high zoom factor. Due the possible displacement of the image collector and the changeable optical power of the fluid lens, and cooperation between these two elements, it is possible to obtain a compact endoscope with a wide dynamic range of zoom factor with satisfactory focusing properties.

    摘要: The present invention relates to an optical probe (1) suitable for miniature applications. An example application is a fibre-based confocal miniaturized microscope. The optical probe comprises a coil-based actuation system (9, 10) comprising drive coils (9) capable of displacing the distal end (3) of an optical guide (2) housed (4) by the optical probe. The probe makes use of a feedback loop which alternate between driving the displacement of the optical guide by driving a current through the drive coils and switching off the current through the drive coils, and while the drive current being switched off, measure the speed of the distal end of the optical guide. The measured speed is compared to the set-point speed, and if a difference is detected, the drive current is adjusted to eliminate, or at least bring down, this difference.

    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: 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.
