Claim 23:
24. An optical imaging system comprising:
an object holder to hold and move an object;
a detector to detect optical signals from the object at a detector surface;
an optical train configured to direct the optical signals onto the detector surface, the optical train having an object plane proximate to the object holder and an image plane proximate to the detector surface, the optical train including a mirror that is rotatable between an imaging position and a focusing position; and
an image analysis module configured to analyze a test image detected at the detector surface when the mirror is in the focusing position, the test image having an optimal degree-of-focus at a focused location in the test image, the focused location in the test image being indicative of a position of the object with respect to the object plane, wherein the object holder is configured to move the object toward the object plane based on the focused location.
