Claim Text:
1. A miniaturized imaging device disposed on a distal end of a catheter, comprising: at least one imaging array disposed on a distal end of the catheter; a lens system disposed on the at least one imaging array; a light source disposed on a distal end of the catheter adapted to propagate a starting monochromatic wavelength of light onto a target and incrementally adjust the starting monochromatic wavelength of light over different time intervals to a different monochromatic wavelength of light, wherein (i) the light source is adapted to incrementally adjust the wavelength of light only until an optimum wavelength of light is detected when the catheter is stationary, and (ii) the light source is adapted to continually incrementally adjust the wavelength of light when the catheter is non-stationary; and a processor coupled to the imaging array configured to generate an image from the plurality of different monochromatic wavelengths of light reflected from the target and further configured to determine an optimal monochromatic wavelength of light to optimize image focus based on the light reflected from the target.
