摘要:
利用光束扩展函数和点扩展函数,计算了在一般海水介质中,同步扫描水下激光成像系统,成像距离和成像质量与目标距离、接收视场角、光斑的大小和光功率等参数之间的数量关系. 结果表明,压缩激光束和采用窄视场接收能有效地提高成像距离和改善成像质量,适当增大激光光功率也能使得成像距离和成像质量有所提高,但当光功率增加到一定值后,性能改善不明显.
Abstract:
Based on the beam spread and the point spread functions, the quantitative relationships of imaging distance and imaging quality with target distance,receiver field angle, facula size and light power in ordinary sea water medium for synchronous scanning underwater laser imaging system are calculated. The results show that the imaging distance can be effectively enhanced and the imaging quality can be availably amended by compressing laser beam, using receiving angle with narrow visual field, and suitably adding light power of laser. But the improvement of the properties is not evident after light power of laser reaches a certain value.
