Starting with ray tracing through a single-mirror beam steering system, an analytical approach is developed to predict the scan pattern on a flat screen. The results for a single-mirror system are then extended to a two-mirror/two-axis beam scanning system, which paves the way to a performance comparison of single-mirror and two-mirror/two-axis laser projection systems. Some fundamental aspects of mirror-based laser projectors of different configurations are investigated, such as maximization of image size on screens of different format, the effect of pixel rotation and size changes on image resolution, and the relationship of angular motion of the mirror in a single-mirror system and the two mirrors in a two-mirror/two-axis system.
