Generalized radiative transfer emulation for imaging spectroscopy reflectance retrievals

Remote Sensing of Environment, 2021
Abstract Estimates of surface reflectance from observed radiance are fundamentally tied to the accuracy of the radiative transfer models used to simulate the interaction of light with the atmosphere and surface. These radiative transfer models are parameterized by a wide range of quantities, ranging from observation and solar geometries to ...

Improved sample characterization in terahertz reflection imaging and spectroscopy

Optics Express, 2009
For imaging applications involving biological subjects, the strong attenuation of terahertz radiation by water means that terahertz pulsed imaging is most likely to be successfully implemented in a reflection geometry. Many terahertz reflection geometry systems have a window onto which the sample is placed - this window may introduce unwanted ...

Towards spatial assessment of carbon sequestration in peatlands: spectroscopy based estimation of fractional cover of three plant functional types [PDF]

, 2008
Peatlands accumulated large carbon (C) stocks as peat in historical times. Currently however, many peatlands are on the verge of becoming sources with their C sequestration function becoming sensitive to environmental changes such as increases in ...

Frequency-wavelet domain deconvolution for terahertz reflection imaging and spectroscopy

Optics Express, 2010
In terahertz reflection imaging, a deconvolution process is often employed to extract the impulse function of the sample of interest. A band-pass filter such as a double Gaussian filter is typically incorporated into the inverse filtering to suppress the noise, but this can result in over-smoothing due to the loss of useful information.
