Using a plane of light formed by focusing light through a cylindrical lens at a narrow angle or by scanning a line of light in a plane perpendicular to the axis of objective, high resolution optical sections can be taken. Single plane illumination, or light sheet illumination, is also accomplished using beam shaping techniques incorporating multiple-prism beam expanders.F. J. Duarte, in High Power Dye Lasers (Springer-Verlag, Berlin,1991) Chapter 2.Duarte FJ (1993), Electro-optical interferometric microdensitometer system, US Patent 5255069 . The images are captured by CCDs. These variants allow very fast and high signal to noise ratio image capture.
