Patent ID: 7813016

Claim:
A nonlinear holographic imaging system comprising: an excitation source for generating at least one optical puke; a first optical splitter for separating said at least one optical pulse into at least one excitation puke and at least one reference pulse; a sample optically aligned with said first optical splitter and comprising a target of interest having at least one nanoparticle incorporated therein, said at least one nanoparticle generating at least one coherent nonlinear harmonic optical emission when radiated by the at least one excitation pulse; an optical filter in alignment with the sample for blocking all emissions from said sample except the at least one nonlinear harmonic emission; a nonlinear homodyne reference generator in optical alignment with said first optical splitter for converting said at least one reference pulse into at least one coherent nonlinear harmonic reference pulse; a second optical splitter in optical alignment with said reference generator and said filter such that the each of the at least one nonlinear harmonic reference pulse and the at least one nonlinear harmonic emission are recombined into at least one holographic signal; and a detector in optical alignment with said second optical splitter for recording said at least one holographic signal.
