Patent ID: 8270054

Claim:
An apparatus comprising: an optical system, wherein the optical system receives a first beam at a first input angle, θ In1 , with respect to an optical axis, and wherein the optical system directs the first beam at a first output angle, θ Out1 , with respect to the optical axis, and further wherein the optical system comprises; a first element whose angular position about a first rotation axis is controllable; a second element whose angular position about a second rotation axis is controllable; and a reflective imager; wherein a change in the angular position of the first element about the first rotation axis by Δθ 1 results in a change in θ Out1 that is greater than |2xΔθ 1 |; and wherein a change in the angular position of the second element about the second rotation axis by Δθ 2 results in a change in θ Out1 that is greater than |2xΔθ 2 |.
