Claim:
1. A method of imaging tissues using non-linear optical media, comprising: placing a medical device within a body of a patient; propagating a predetermined wavelength of light onto a target tissue located within the body of the patient from a distal end of the medical device, said predetermined wavelength of light being greater than 700 nanometers; receiving a portion of the predetermined wavelength of light propagated from the device and reflected from the target tissue into and through a lens system; passing the predetermined wavelength of light from the lens system into and through a non-linear optical media, the non-linear optical media being disposed in series with and behind the lens system; reducing the predetermined wavelength of light passed through the non-linear optical media at least by half; and receiving at least a portion of the at least halved wavelength of light onto a silicon-based solid state imaging device.
