The invention relates to a microscope and a method for producing 3D images of various transparent or semi-transparent samples, fundamentally comprising: causing a relative movement according to the detection direction between the sheet of light and the sample while maintaining a constant angle of acquisition; producing, for said angle of acquisition, a single 2D projection image formed by a representative parameter for each pixel; modifying the angle of acquisition by means of a relative rotation between the sheet of light and the sample, combined with a relative vertical translation between the sheet of light and the sample, and repeating the previous steps; and generating a 3D image of each of the samples from the set of 2D projection images that are produced.

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.
