A tomographic imaging method which includes the steps of activating fluorescence in a surface layer of a protein-marked or fluorescent dye-marked biological tissue sample not emitting fluorescence or only emitting specific fluorescence to acquire an activated surface of biological tissue sample; performing fluorescence excitation on the acquired surface biological tissue sample, and imaging the fluorescence to acquire a fluorescence image of the surface layer; cutting off the surface layer; exposing an inactivated new surface layer after cutting the surface layer; repeatedly performing activating, imaging and cutting off steps for the new surface layer to repeat tomographic imaging in such a manner till acquiring a two-dimensional image of each layer of the biological tissue sample; and overlapping the two-dimensional images to acquire a complete three-dimensional image of the biological tissue sample, thus acquiring three-dimensional structure information of the entire sample.

The light control device includes a light modulation module and a dispersion compensation module. The light modulation module is used for modulating an incident light field to obtain a target diffraction light field. The dispersion compensation module is used for performing dispersion compensation on the target diffraction light field, so that light fields having different wavelength in the target diffraction light field have the same spatial location distribution, or the light fields having different wavelength in the target diffraction light field have the same spatial angle distribution.

A light pulse positioning apparatus with dispersion compensation includes an acousto-optical device and a dispersive element optically coupled thereto. The dispersive element is placed and oriented in relation to the acousto-optical device to spatially and temporally disperse the light pulse and thus compensate, respectively, a spatial dispersion and a temporal dispersion caused by the acousto-optical device. The acousto-optical device can include one or more acousto-optical deflectors for one-dimensional or two-dimensional laser pulse positioning. The dispersive element can be a prism placed in front of the acousto-optical device. In a two-dimensional configuration, a single prism, if properly oriented, is sufficient for dispersion compensation of both acousto-optical deflectors.
