ARMES camera views

StarTiger's Autonomous Refocusing Mechanism System, ARMES, is based on automatically comparing the phase shift per CCD pixel of a pair of auxiliary detectors on either side of the main camera. These two detectors estimate the correct depth by settling on the focus from their slightly differing perspectives where mutual phase shift is least and their views are most similar. In the image above, the target stage is exaggeratedly moved along the optical axis to have defocus visible to the human eye.
