Zusammenfassung:This invention relates to one fix laser top device to measure rotation speed or relative angle position, which eliminates blind area without adding measurement error of special optical device to improve optical device, wherein, the method gets the total optical fix laser device without blind area; these devices comprise bias separation optical device, inverse light rotation and non-reverse light rotation device to avoid mode lock through different chambers by four linear bias modes.
