    摘要: Methods and apparatus for optical imaging and scanning of holes machined, drilled or otherwise formed in a substrate made of composite or metallic material. The method utilizes an optical instrument for imaging and scanning a hole in combination with an image processor configured (e.g., programmed) to post-process the image data to generate one complete planarized image without conical optical distortion. The optical instrument includes an optical microscope with confocal illumination and a conical mirror axially positioned to produce a full 360-degree sub-image with conical distortion. In the post-processing step, a mathematical transformation in the form of computer-executable code is used to transform the raw conical sub-images to planar sub-images. The planarized sub-images may be stitched together to form a complete planarized image of the hole.

    摘要: An assembly for switching optical paths, which assembly includes multiple optical channels for guiding an illuminating light to a specimen and for guiding the light coming from the specimen to an image recording unit. The assembly also includes a plurality of light guiding mirrors and at least one light modifying element in each optical channel for directing the illuminating light and the light coming from the specimen. In each of the multiple optical channels the at least one light modifying element includes a stationary dichroic mirror. Further details regarding the arrangement and rotation of the mirrors, and how the mirrors direct the illuminating light and light coming from the specimen, are defined herein.

    摘要: High speed laser scanning systems and methods are disclosed for imaging target samples. Embodiments of the laser scanning systems and methods include separating a laser beam into two or more different pathways and pulsing light along the two or more pathways. The different pathways intersect the surface of a moving mirror at different locations and light traveling in a pathway that is being approached by an edge of the moving reflective surface is turned off while light traveling in a different pathway that is farther from the edge of the moving reflective surface is turned on. Embodiments include reflective surfaces that form a rotating polygonal scanner. Further embodiments include recombining the two or more different pathways, focusing the laser light on a test sample, and imaging the light reflected from the test sample.

    摘要: A microscope apparatus includes: an objective lens; an observation optical system that makes the specimen be irradiated with excitation light by the objective lens, and acquires image information of the specimen; a first stimulation optical system that includes a scanning section which scans stimulus light, makes the scanning section scan an irradiation position of the stimulus light and applies an optical stimulus to the specimen; a second stimulation optical system that includes an SLM arranged at a pupil conjugate position of the objective lens and capable of modulating a phase of the stimulus light, selectively switches the irradiation position of the stimulus light by the SLM and applies the optical stimulus to the specimen; and a light path selecting section that selects at least one of a light path of the first stimulation optical system and a light path of the second stimulation optical system.
