摘要：
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). A light source (502, 602, 702, 802) provides light to the scan mirror (130); and circuitry analyzing the light reflected to determine the position of the oscillating portion (204).
