摘要
绝对衰减系数是表征海水固有光学特性的一个重要参数,现场测量水体绝对衰减系数对于水下光电探测领域具有重要价值.VIPER高光谱衰减测量仪可以用来测量水体衰减系数,相较于AC-S水体衰减系数测量仪具有比较明显的成本优势.但VIPER只能测量水体的相对衰减系数,无法直接得到水体绝对衰减系数.针对这一问题,本文给出了一种基于VIPER的水体绝对衰减系数现场测量方法,推导了 VIPER测量水体绝对衰减系数的基本公式,设计实验验证了 VIPER测量水体绝对衰减系数的可靠性.对比实验结果表明,本文给出的基于VIPER的水体绝对衰减系数现场测量方法具有较好的准确性和可靠性.本文方法可使VIPER用于各种水下光电探测领域,实现对水体绝对衰减系数的快速定标.
Abstract
Absolute attenuation coefficient is an important parameter to characterize the intrinsic optical properties of seawater,and its measurement in the field of water body absolute attenuation coefficient is of great value in the field of underwater photoelectricity detection.VIPER hyperspectral attenuation meter can be used to measure the attenuation coefficient of the water body,and it has a relatively obvious cost advantage compared with AC-S meter.However,VI-PER can only measure the relative attenuation coefficient of the water body,and cannot directly obtain the absolute at-tenuation coefficient of the water body.To address this problem,this paper gives a VIPER-based field measurement of the absolute attenuation coefficient of the water body,the derivation of the basic formula for the VIPER measurement of the absolute attenuation coefficient of the water body,and the design of experiments to verify the reliability of the VIPER measurement of the absolute attenuation coefficient of the water body.Comparative experimental results show that the field measurement method of absolute attenuation coefficient of water body based on VIPER given in this pa-per has good accuracy and reliability.The method of this paper can make VIPER used in various underwater photoe-lectric detection fields,and realize the rapid calibration of the absolute attenuation coefficient of the water body.
