Abstract: An optical device having a total internal reflection (TIR) switch is able to switch to form two different optical imaging paths. Each optical imaging path has different optical characteristics that causes a detector to capture different imagery depending upon which optical imaging path is used. The TIR switch is switchable between a TIR state and a transmission state to control which optical imaging path is used by the device for imaging.
