摘要：
A single disc of radius R carries n cylindrical mirrors of radius of curvature r on its circumference and rotates at frequencies of typically 30 Hz. A beam is deflected successively by the mirrors to scan n lines in a two-dimensional array for every revolution if the mirrors have different inclinations or n times the same line if they have identical inclination. The angular sweep speed and the angular field of view can be (1 plus R/r) times larger and the field of view is flatter than for usual polygon with flat mirrors.
