Abstract
A micro-thrust and micro-impulse application device and method generates micro-thrust to a target by light pressure action from laser reflection. The device comprises a laser, a laser adjustment device, a beam splitter, a shutter, a reflector, and a laser power meter. Laser beam is generated by laser, adjusted by laser adjustment device, and divided into two paths by beam splitter. Laser in one path is measured at laser power meter; power measured determines magnitude for micro-thrust. In another path, it irradiates on the reflector on the target via shutter for generating micro-thrust. Light reflected by the reflector arrives at another laser power meter. Power of two laser paths are measured in real time by two laser power meters, acting micro-thrust is calculated by combining parameters including reflectivity and incident angle of laser irradiating the reflector, and light output power of the laser is adjusted in real time.
