Abstract
A scanning projector includes a mirror that scans in two dimensions. The scanning mirror oscillates at a resonant frequency on a fast-scan axis, and is phase locked to an incoming frame rate on a slow-scan axis. An interpolation component interpolates pixel intensity data from adjacent pixels based on the position of the mirror when a pixel clock arrives. Incoming video data is stored in a buffer. Less than a complete frame of video data may be stored in the buffer.
