TIME GATED IMAGING THROUGH SCATTERING MATERIAL USING POLARIZATION AND STIMULATED RAMAN AMPLIFICATION |
摘要 |
An apparatus for imaging into or through scattering materials (17) includes a source (20) for producing a broadband laser reference beam (R) and a Stokes illumination beam (Si) correlated to the reference beam. The Stokes illumination beam is transmitted into the scattering material to obtain a Stokes signal beam (Ss) having a first image carrying component and a first nonimage component. The reference beam and the Stokes signal beam are then separately delayed (Rd, Sd) and polarized (Rp, Sp), after which they are combined to produce a combined beam (C) having a Stokes component and a reference component. A Stimulated Raman amplifier (30) responsive to the combined beam produces an amplified signal beam (A) in which the image carrying component has been amplified by a higher gain factor than the nonimage component. |
