Abstract:
1. A micro-camera catheter device, comprising: at least one light source disposed on a distal end of a catheter, said light source capable of propagating a predetermined wavelength of light with a wavelength between approximately 1000 nanometers and approximately 2000 nanometers onto a target; a circular lens system disposed on the distal end of the catheter, said lens system configured to receive light reflected from the target; a circular non-linear optical media disposed directly behind and in contact with the lens system, the non-linear optical media configured to modify reduce the wavelength of the light reflected from the target to below approximately 700 nanometers; and a circular linear optical disposed directly behind and in contact with the circular non-linear optical media; and a silicon-based solid state imaging device disposed behind the linear optical media, said silicon-based solid state imaging device configured to receive light from the linear optical media, wherein the outer circumference of the circular lens, circular non-linear optical media and linear optical media are substantially the same, wherein the non-linear optical media comprises a non-linear optical crystal.
