Patent ID: 8670020

Claim:
A stationary lens system for performing a two dimensional scan of a scene, the system comprising: a stationary lens having an optical axis; a first scan mirror having a first axis, the first axis being parallel to a light-reflecting surface of the first scan mirror, the first scan mirror pivoting about the first axis to direct images of the scene along a first dimension, the first scan mirror directing the images of the scene along an optical path; a second scan mirror having a second axis, the second scan mirror being located in the optical path between the first scan mirror and the stationary lens, the second scan mirror pivoting about the second axis to direct images of the scene to the stationary lens along a second dimension, the second axis being substantially perpendicular to the optical axis of the stationary lens, the second dimension being perpendicular to the first dimension; and at least one actuator that controls the first and the second scan mirrors to step through multiple positions to perform the two dimensional scan of the scene, wherein the first and second scan mirrors stop and stare to acquire a scene image at each of the multiple positions without causing the scene images to appear to rotate on the stationary lens through the multiple positions.
