Technical Examples

A projection optical system includes a light source, a digital micromirror device (DMD), a projection lens and a first block sheet. The light source provides an illumination light. The DMD includes a plurality of micromirrors, and the angles of each micromirrors are changed individually according to an input signal for separating the illumination light reflected from the micromirrors into a signal light, a first stray light and a second stray light. The signal light passes through the projection lens and is further projected onto a screen. The first block sheet is disposed closely to the projection lens to allow the first stray light and the second stray light to be fully shielded off by the first block sheet and thus not to reach the projection lens.
