Abstract
In an imaging system and method are disclosed, including a first illumination source for producing a first illumination field, a modulation system for modulating the first illumination field, and an optical imaging system for directing the modulated illumination field to an imaging surface. The optical imaging system includes at least one optical lens for directing the modulated illumination field toward the imaging surface along the optical axis of said optical lens. The at least one optical lens includes a first surface facing the modulation system and a second surface facing the imaging surface. The optical imaging system also includes a second illumination source for producing a second illumination field. The second illumination field has a frequency that is different than the frequency of the first illumination field. The optical imaging system also includes an optical assembly for directing the second illumination field toward the imaging surface along an optical path that is different than the first optical path such that the second illumination field contacts the first surface of the at least one optical lens from a direction other than that which is normal to the first surface of the at least one optical lens. The optical imaging system also includes a sensor assembly for receiving the second illumination field after it is reflected off of a portion of the imaging surface, and for producing a sensor output signal. The optical imaging system also includes a control assembly for adjusting the position of the at least one optical lens responsive to the sensor output signal.
