A comparative analysis of the ‘transmittance’ method between using integrating sphere and filter holders for measuring light absorption by aquatic particles Conference Paper uri icon

abstract

  • Measuring light absorption of suspended matter in water is essential for water color remote sensing. The 'transmittance' method, which is based on the Quantitative Filter Technology, is one of the most widely used methods to determine absorption of suspended matters in water. This method measures optical density of suspended matters that concentrated on the filter and then calculate absorption by applying light pathlength amplification correction to the optical density. Either a pair of filter holders or an integrating sphere is the necessary accessory for the measurement of the optical density. However, according to our research, we discovered that the results obtained with different accessories have some differences. By comparing the optical density values that measured with different accessories, we analyzed the difference between different accessories and proposed a revised model for light pathlength amplification correction. 2012 IEEE.
