Abstract:
A system for providing recognition of a distant object, comprising:an illumination source for transmitting light radiation to the distant object; an imaging device having a detector element including a plurality of pixel elements and a lens, the lens detecting the light radiation reflected from the distant object to generate an image of the object corresponding thereto; and a digital signal processor element electrically connected with the imaging device, the digital signal processor element dynamically calculating a desired optical magnification of the lens as a function of a distance between the imaging device and the distant object, generating a voltage corresponding to the desired optical magnification and applying the voltage to the imaging device to adjust a magnification of the lens wherein the magnification adjustment is applied to each pixel element within a field of view of the detector element so that the image of the distant object is held in a fixed dimension for a predetermined period of time sufficient to capture the reflected light radiation.
