Imaging systems and methods

摘要

Imaging systems and methods are provided. In one embodiment, an image system is disclosed that comprises a Raman gain medium (20) configured to receive an image from a target area (12) and a tunable laser (18) configured to pump light into the Raman gain medium over a plurality of first wavelengths to induce amplification of the image over a plurality of second wavelengths stokes shifted from the plurality of first wavelengths. The image system further comprises an image detector system (28) that receives and processes the amplified image over the plurality of second wavelengths.
