1. A method for 3D imaging of a biological object in an optical tomography system comprising: moving a biological object relative to a microscope objective to present varying angles of view; illuminating the biological object with radiation having a spectral bandwidth limited to wavelengths between 150 nm and 390 nm; sensing radiation transmitted through the biological object and the microscope objective with an ultraviolet camera; forming a plurality of pseudoprojection images of the biological object from the sensed radiation; and reconstructing the plurality of pseudoprojection images to form a 3D image.
