文摘Weak images,which pass through two kinds of suspension media with sizes of randomly-moving suspension particles about 0.05-0.1 cm and 0.01-0.001 cm respectively,are deteriorated by light scattering of particles,but restored and amplified effectively by two-wave mixing in photorefractive crystals with different time constants.
