METHOD AND DEVICE FOR WAVELENGTH SHIFTED IMAGING

A micro-camera catheter device is disclosed having at least one light source disposed on a distal end of a catheter. The light source is capable of propagating a predetermined wavelength of light with a wavelength greater than approximately 700 nanometers onto a target. The device further includes a lens system disposed on the distal end of the catheter, said lens system configured to receive light reflected from the target. The device further includes a non-linear optical media disposed about the lens system configured to reduce the wavelength of light reflected from the target. The device also includes a silicon-based solid state imaging device disposed behind the non-linear optical media configured to receive light from the non-linear optical media.
