ABSTRACT:
A single-aperture passive rangefinder and a method of determining a range. In one embodiment, the single-aperture passive rangefinder includes: (1) an imaging system configured to form a first image that includes a point of interest at a first position and a second image at a second position that includes the point of interest and (2) a processor associated with the imaging system and configured to acquire and store the first image and the second image and determine a range to the point of interest based on a separation between the first position and the second position and a position of the point of interest relative to virtual axes of the imaging system at the first position and at the second position.
