ABSTRACT:
An image projection system (100) has a laser (102, 104, 106) providing at least one beam (103, 105, 107) to a scan mirror apparatus (130) for scanning the at least one beam (103, 105, 107) in two orthogonal directions (404, 406). The scan mirror (130) includes an oscillating portion (204, 904) disposed contiguous to a frame (202) and includes a reflective portion (218, 918) capable of reflecting the beam (103, 105, 107). Circuitry (500) is provided for measuring the capacitance between interdigitated teeth (212, 214, 912, 914) on the frame (202) and the oscillating portion (204, 904).
