Abstract

A method of imaging a target using a miniaturized imaging device is disclosed comprising providing a miniaturized imaging device having a stationary lens system and an imaging array, wherein the distance from a distal end of the stationary lens system to the imaging array is fixed. The miniaturized imaging device is advanced near the desired target and a distance from a distal end of the stationary lens system to the desired target is determined. A desired wavelength of light is calculated based on the determined distance from the distal end of the stationary lens system to the desired target and the desired wavelength of light is propagated onto the target.
