我们评估的点源积分腔吸收计（PSICAM）的理论性能与蒙特卡罗模拟和灵敏度分析。我们量化的散射误差，验证它们是可以忽略不计的大多数海洋光学应用。尽管PSICAM检测器响应对壁反射率的值高度敏感，但是如果选择适当的参考溶液，则可以用PSICAM准确地确定未知流体的吸收。我们还量化的错误，如果源是不完全各向同性的结果，发现适量的源各向异性可以容忍的检测器是正确定位相对于源。
We evaluate the theoretical performance of a point-source integrating-cavity absorption meter (PSICAM) with Monte Carlo simulations and a sensitivity analysis. We quantify the scattering errors, verifying that they are negligible for most ocean optics applications. Although the PSICAM detector response is highly sensitive to the value of the wall reflectivity, the absorption of an unknown fluid can be accurately determined with a PSICAM if appropriate reference solution(s) are chosen. We also quantify the error that results if the source is not perfectly isotropic, finding that moderate amounts of source anisotropy can be tolerated provided that the detector is properly located with respect to the source.
