中文摘要: Semiconductor laser is paid more attention and widely used in laser range finder, laser fuse and laser guidance due to its monochromaticity, coherence and high density, as well as small volume and low power consumption. The principle of laser encoding and emitting system is set forth. Based on the principle of spatial frequency-encoding, a laser encoding-emitting system is developed; a new laser encoding mode is designed, which can transfer continuous laser into pulse laser with different frequencies, they represent different position. The mathematic model to calculate the deviation from center is obtained. A new encoding pattern is designed, which is composed of two light paths crossed 90 degrees. Azimuth information of target is given in orthogonal coordinate system and deviation from center is linearity. As well as, characteristic distribution of spatial laser field is analyzed and irradiance distribution is homogeneous. Laser diode is directly applied as guidance source and information carrier in place of solid-state laser. Output power of a single laser diode can reach 3w. Two laser diodes are installed in series for increasing output power in the system. Tested in 2 kilometers outdoor; experimental results prove that: the receiver can receive correctly the signal emitted by system. The laser encoding mode can satisfy guidance precision demand.
