Abstract: Systems and methods herein provide improved, high-throughput multiphoton imaging of thick samples with reduced emission scattering. The systems and methods use structured illumination to modify the excitation light. A reconstruction process can be applied to the resulting images to recover image information free of scattering. The disclosed systems and methods provide high throughput, high signal-to-noise ratio, and high resolution images that are depth selective.

Abstract: The information budget of a light field microscope is increased by increasing the field of view and image circle diameter of the microscope, while keeping the ratio of overall magnification of the microscope to the numerical aperture of the microscope unchanged. Alternatively, the information budget is increased by increasing the field of view and image circle diameter of the microscope by a first factor, while increasing the ratio of overall magnification of the microscope to the numerical aperture of the microscope by a smaller, second factor. In some cases, an infinity-corrected light field microscope has an overall magnification that is greater than the nominal magnification of the objective lens.

Abstract: The disclosure relates to measurement and classification of tissue structures in samples using a combination of light imaging and spectroscopy, in particular although not necessarily exclusively for detection of tumors such as basal cell carcinoma or breast tumors in tissue samples. Embodiments disclosed include a method of automatically identifying tissue structures in a sample, the method comprising the steps of: measuring (1702, 1703) a response of an area of the sample to illumination with light; identifying (1704) regions within the area having a measured response within a predetermined range; determining (1705) locations within the identified regions; performing (1706) spectroscopic analysis of the sample at the determined locations; and identifying (1707) a tissue structure for each region from the spectroscopic analysis performed on one or more locations therein.
