摘要：
A rapid iris acquisition, tracking, and imaging system can be used at longer standoff distances and over larger capture volumes, without the active cooperation of subjects. Eye reflections from the subjects eyes are used to steer a high resolution camera to the eyes in order to capture images of the irises. A circular deformable minor driven by one or more annular forces can be used to focus the camera. A circular mirror substrate is mounted by its circumference onto a minor mount and driven by an annular drive element that contacts the minor substrate along a ring. If the annular drive element has a certain diameter relative to the circumference of the mirror substrate, the mirror substrate will be deformed in the shape of a sphere.
