Abstract:
1. An optical imaging apparatus comprising: an optical signal source configured (i) to generate an optical signal including a carrier signal and an imaging signal, and (ii) to guide said optical signal to a sample; an optical signal detector apparatus configured (i) to detect a modified optical signal from said sample, and (ii) to generate an electrical image signal based on said modified optical signal, said electrical image signal including a background component and a modulated image signal corresponding to an image of said sample; and a resonant amplifier assembly electrically coupled to said optical signal detector apparatus and configured (i) to isolate said modulated image signal from said background component, (ii) to amplify said modulated image signal, and (iii) to rectify said modulated image signal.
