An optical switch using Risley prisms and rotary microactuators to independently rotate the wedge prisms of each Risley prism pair is disclosed. The autorefractor detector system, in conjunction with a secondary light source, uses one photodetector such as a charge coupled device or one photodiode, to intercept a light beam at two distances from a secondary retinal light source created by one relay lens, one pupil emitter conjugate lens and one pupil detector conjugate lens. For example, a Wi-Fi Access Point can broadcast two overlapping networks in the same location: a public network, and a private network. Optional user-inputted settings can affect the trip setting adjustments, such as transient loading conditions that can influence the SCCA estimates.
