Variable orientation illumination-pattern rotators ("IPRs") that can be incorporated into structured illumination microscopy instruments to rapidly rotate an interference pattern are disclosed. An IPR includes a rotation selector and at least one mirror cluster. The rotation selector directs beams of light into each one of the mirror clusters for a brief period of time. Each mirror cluster imparts a particular predetermined angle of rotation on the beams. As a result, the beams output from the IPR are rotated through each of the rotation angles imparted by each of the mirror clusters. The rotation selector enables the IPR to rotate the beams through each predetermined rotation angle on the order of 5 milliseconds or faster. |
