    摘要: 0 The mechanism for moving the lens assemblies mounted to support rods in a variation power. microscope includes a crank shaft having a pair of opposed arms. The lens assemblies are connected to the crank arms by linkages. The lens assemblies are biased to the support rods by resilient member. At least one of the crank arms may incorporate a motion correcting surface which cooperates with a cam follower fixed to the associated linkage to vary the length of the linkage.
    The lens assemblies may further include arms for stabilizing guiding them along the support rods. Still further, the mechanism may include a device for controlling the rotation in either direction of the crank shaft. Additionally, the lens assemblies may be adjustably fixed to the linkages.

    摘要: [Object] To provide a medical observation apparatus and a medical observation system that can ensure the user's visual field and have good manipulability. [Solution] A medical observation apparatus includes: a cylindrical unit; an imaging unit provided in a hollow portion of the cylindrical unit and including an optical system configured to collect light from an object to be observed and form an image, and an imaging element configured to photoelectrically convert light collected by the optical system and output an imaging signal; a support unit including at least one set composed of two arm units and a joint unit linking one of the two arm units to the other in a rotationally movable manner and supporting, at its tip portion, the cylindrical unit and the imaging unit in a rotationally movable manner around an axis in a height direction of the cylindrical unit; and an arm manipulation unit provided on a side surface of the cylindrical unit corresponding to an upper side of an image based on the imaging signal and configured to accept a manipulation input that permits a rotational movement of the arm unit.

    摘要: A viewing apparatus for producing a stereoscopic image for an observer, the viewing apparatus comprising: first and second video projectors for projecting respective ones of first and second video images of an object, the first and second images being different images which are one or both of spatially and angularly shifted in relation to the object so as to convey parallax between the images; a mirror arrangement comprising a concave mirror which receives light from the first and second video projectors, the mirror arrangement being located in relation to the first and second video projectors such that focussed images of the object are produced at the mirror arrangement; and a viewing lens for relaying exit pupils corresponding to each of the focussed images as reflected by the mirror arrangement to a viewing plane so as to be viewable at the respective eyes of the observer as a stereoscopic image without use of adapted eyewear; wherein the video projectors comprise first and second video displays which are driven by first and second video signals to display respective ones of the first and second video images, and first and second optical arrangements for focussing light from the respective images as displayed by the first and second displays to the mirror arrangement.

    摘要: Some embodiments of the present inventive concept provide optical coherence tomography (OCT) systems for integration with a microscope. The OCT system includes a sample arm coupled to the imaging path of a microscope. The sample arm includes an input beam zoom assembly including at least two movable lenses configured to provide shape control for an OCT signal beam; a scan assembly including at least one scanning mirror and configured for telecentric scanning of the OCT signal beam; and a beam expander configured to set the OCT signal beam diameter incident on the microscope objective. The shape control includes separable controls for numerical aperture and focal position of the imaged OCT beam.
