| 摘 要： | 利用双流辐射理论，导出了信号光辐射照度的表达式。从理论上计算了同步扫描系统的信号光和后向散射光传到探测器的辐照度与衰减长度的定量关系。减小视场角和增大光源到探测器的距离可增成像距离。

| Abstract: | It is derived that the irradiant expression of signal light by two flux irradiant transmiting theory.We calculate the quantity relationships between attenuation lengths and irradiance in the synchronous scanning system.The imaging distances can be increased by means of decreasing angle of receive and improving distance from the source to the detector.The theory value of the imaging distances is about 12 attenuation lengths in ordinary water. |
