摘要： The present invention relates to the optical system in a laser scanning eye fundus camera. The optical system comprises an illuminating optical system for scanning an eye fundus with an illuminating laser light beam from a light source using a light scanning device, a light receiving optical system for directing the reflected light from the eye fundus to a light receiving unit; a beam diameter adjusting system associated with the optical systems for adjusting the beam diameter of the laser beam or of the light for observation; and a system for interlocking the adjustment of the beam diameter adjusting system with the adjustment of the magnification adjusting system wherein an adjustments of the magnification adjusting system to increase the magnification causes the beam diameter adjusting system to be adjusted to reduce the beam diameter. Such arrangement according to the present invention allows the adjustment of the depth of field by adjusting the aperture diameter of the optical system by the beam diameter adjusting system so that a test or inspecption of uniform or even quality can be ensured for all subjects in spite of variations in their age, experience of medical or opthamological tests or inspections, or structure of the eye fundus.

摘要： A method and system are proposed to obtain a reduced speckle noise image of a subject from optical coherence tomography (OCT) image data of the subject. The cross sectional images each comprise a plurality of scan lines obtained by measuring the time delay of light reflected, in a depth direction, from optical interfaces within the subject. The method comprises two aligning steps. First the cross sectional images are aligned, then image patches of the aligned cross sectional images are aligned to form a set of aligned patches. An image matrix is then formed from the aligned patches; and matrix completion is applied to the image matrix to obtain a reduced speckle noise image of the subject.

摘要： An optical coherence tomography (OCT) image composed of a plurality of A-scans of a structure is analysed by defining, for each A-scan, a set of neighbouring A-scans surrounding the A-scan. Following an optional de-noising step, the neighbouring A-scans are aligned in the imaging direction, then a matrix X is formed from the aligned A-scans, and matrix completion is performed to obtain a reduced speckle noise image.

摘要： A rotary laser system comprising a body (1), and a plurality of object reflectors including a first object reflector (2) and a second object reflector (3). The body (1) includes a rotating unit for emitting light to the object reflectors; a detector for detecting the reflection from the object reflectors, the reflection being incident upon the body through the rotating unit; and a detecting circuit for discriminating the object reflectors depending on the output of the detector, so that the location and range to be scanned with a laser beam may be determined on the basis of the detection result. The reflection surface of each object reflector is divided into at least two. The marking operation can be accurately carried out by reciprocal scanning to confirm the position to be irradiated on the first object reflector while confirming the scanned position on the second object reflector. The dislocation, if any, of the rotary laser system after installed can be easily detected and corrected to ensure the accuracy in the marking operation.

摘要： A projection inspector which projects the image of an object being measured onto a screen for a visual inspection. It may be used with a microscope for observation in detail. Unlike the conventional projection inspector, the inspector fully exhibits high degree of measuring function even at the time of inspecting an object having a surface color and shape that can be difficultly imaged, and projects the object's image onto the screen to inspect it, and further enables the object's image to be more correctly observed or inspected using a microscope. The projection inspector is provided with a projection lens mount that is movable two-dimensionally and mounts a projection lens that constitutes a portion of the projection optical system over a plate on which the object to be measured is placed, and the object's image is projected onto the screen via the projection optical system as it is irradiated with the light of illumination, wherein the projection lens mount is replaceable by a microscope mount having an eyepiece, a reference index is provided in the visual field of the eyepiece, and the plate is provided with an indicator that indicates the amount of movement.
