摘要: The present disclosure discloses methods and systems for laser distance measuring, focusing methods and systems, and devices for auto-focusing analysis. The method for laser distance measuring includes: emitting an incident ray α having an incident angle δ to a reflective surface of a laser reflecting mirror (31), the incident ray α being reflected by the laser reflecting mirror (31) to generate a first reflected ray β, and the first reflected ray β irradiating an object to be measured (1000); capturing a second reflected ray θ and generating a laser image on a laser imaging plane (3221), the second reflected ray θ being generated by the reflective surface of the laser reflecting mirror (31) reflecting a return ray γ generated after the first reflected ray β irradiates a surface of the object to be measured; and determining, based on the laser image, a measurement distance A according to a geometrical trigonometry. The height of a base of a triangle is equal to the measurement distance A. The base of the triangle is a connection line L of an emitting point of the incident ray α and a receiving point of the second reflected ray θand a vertex angle of the triangle is an intersection angle of the incident ray α and an extension line of the second reflected ray θ.

摘要: A fluorescent microscopic imaging method and apparatus, comprising: according to experiment requirements, illuminating at least one monochromatic fluorescence excitation light source (101) of the same colour from amongst a plurality of monochromatic fluorescence excitation light sources (101) as a target light source, the monochromatic fluorescence excitation light emitted by each monochromatic fluorescence excitation light source (101) being obliquely emitted onto a preset detection area of a sample plate to be detected; on the side of the sample plate to be detected furthest from the target light source, collecting the fluorescence of the particles in the preset detection area excited by the irradiation of the monochromatic fluorescence excitation light emitted by the target light source, and amplifying the preset detection area to a preset multiple; implementing light-filtering processing of the excited fluorescence of the particles in the preset detection area; and acquiring a fluorescent image of the preset detection area. A two-colour mirror is not required, and the fluorescence microscope apparatus therefore has a simple structure and low cost, preventing light energy loss. As the monochromatic fluorescence excitation light is obliquely emitted onto the sample plate to be detected, a small amount of monochromatic fluorescence excitation light is emitted into an objective lens after passing through the sample plate to be detected.
