Abstract
A scanning projector includes a scanning mirror that sweep a beam in two dimensions. Tangential distortion in a fast-scan dimension is compensated by incorporating a tangent function when determining the light beam location and interpolating pixel data. Tangential distortion in a slow-scan dimension is compensated by driving the scanning mirror nonlinearly in the slow scan dimension such that the light beam sweeps across the display surface at a constant rate.
