摘要：
A method of tomographic imaging is proposed in which two-wave mixing in a photorefractive crystal is used with wavelength scanning of a laser diode and phase modulation of the pump beam. This method provides full optical processing and is effective for weak light from objects because of the use of two-wave mixing. The depth resolution of the method was similar to 1 cm when the wavelength-scanning width was similar to 0.02 nm. (C) 2000 Optical Society of America OCIS codes: 170.4500, 170.1650, 190.7070.
