    摘要: The present invention relates to an optical scanning probe assembly for microscopic guide optic scanning and inspection of tissues suitable for application in, e.g. in vivo medical inspection and biopsy. The assembly comprises an outer housing (3) comprising: i) a spring element for a scanning motor, the spring element formed as a hollow tube (5) adapted to receive an optical guide, the hollow tube having mechanical stiffness larger than the optical guide to be received, ii) a lens system (7) and iii) N means for deflecting (6) the distal end of the hollow tube in directions transverse to the longitudinal extension of the hollow tube, so as to form an optical scan pattern. The optical assembly is particularly advantageous as it increases the freedom to optimize the optical and mechanical performance of the system which is defined respectively by the optical guide and by the hollow tube. The probe can be used in resonant and non-resonant scanning modes.

    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: 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: An optical system for detecting light from a 2D area of a sample (36) comprises a collection lens (34) for collecting light from a collection region of the sample. A light detector (44) is positionally fixed with respect to the sample, and a reflector arrangement (61) directs collected light to the detector. The reflector arrangement comprises movable components and the collection lens (34) is movable relative to the sample. The collection lens and the movable components are configurable to define different collection regions, and the movement of the components effects a direction of the light from the collection region to a substantially unchanged area of the light detector (44). This arrangement avoids the need for a bulky detector in order to detect signals from a 2D sample area formed by scanning across the sample.
