An apparatus and method allowing an optimized illumination in a light profile microscope by excitation of a sample with an elliptically collimated beam. The beam, which is typically supplied by a laser is collimated with unequal beam waist radii (and Rayleigh ranges) along major and minor axes orthogonal to a propagation direction, and approximates a plane sheet of illumination. The plane sheet of illumination is aligned with a thinnest width dimension thereof along the optic axis of the microscope objective, and with a center thereof at the object plane of the objective. Excitation light in a test sample is thereby confined to within a narrow thickness of the object plane of the objective lens, which minimizes out-of focus light in the image. The major axis width of the plane illumination sheet is typically a factor of ten or more greater than the minimum width, allowing a large area of the test sample to be illuminated and imaged. This excitation arrangement optically emulates the operation of micro-toming a thin cross section of a material for analysis, and provides optimum resolution and field in a light profile microscope.

The invention belongs to the field of three-dimensional reconstruction technology, and relates to a multi-view stereo matching three-dimensional reconstruction method of a disordered image. According to the method of the invention, at a view selection algorithm part, 1), for aiming at a global view selection process, firstly a decision condition is introduced; and furthermore the number of views in a candidate view set is fixed adaptively instead of the view set with fixed number of views. No scoring is performed on the views which do not satisfy a condition in an algorithm. Along with continuous expansion of an application range, the number of views in an experiment data set gradually increases, and reduction of view selection time is very important. 2), For a local view algorithm, the method improves a weight influence factor of a polar plane included angle between a neighbor view and a reference view, so that the selected neighbor view is more accurate and more representative. 3), In a view matching area increasing process, the invention provides an adaptive shape space plane sheet algorithm, an adaptive shape can adaptively adapt boundary information, thereby better matching a result.
