Spectroradiometers - an overview | ScienceDirect Topics
The OCI spectroradiometer will have higher spectral resolution (∼5 nm contiguous bands) than historical and contemporary satellite sensors (see Table 6), ranging from the UV (∼350 nm) to NIR (∼900 nm), and will potentially be flown with multi-angle polarimeters as secondary instruments in its payload. Accordingly, it is prudent to pursue ...
Spectroradiometers - an overview | ScienceDirect Topics
2002年5月4日 · Spectroradiometer measurements have demonstrated that surface parameters, such as the LAI, are related to radiometric measurements. Thus, LAI can be estimated from radiometric information through an empirical relationship or a physical model inversion. The following section discusses general methods to estimate the LAI from remotely sensed data.
Unmanned aerial system based spectroradiometer for monitoring …
2019年6月1日 · Spectroradiometer measurements and flight track records were synchronized based on takeoff and landing events to obtain position estimates for every sUAS spectroradiometer measurement. All sUAS flights of each sUAS were conducted by a FAA Part 107 licensed operator, observing all relevant FAA regulations.

Developing a spectroradiometer data uncertainty methodology
2017年6月1日 · The values for a LI-COR 1800 spectroradiometer are listed in Table 2 and used in Section 3.3 when evaluating the uncertainties of the LI-COR spectroradiometer.u v: The standard uncertainty of the voltage coming from the spectroradiometer when measuring the lamp is denoted as u V. This is the net variation in the voltage at each wavelength that ...
Reflectance processing of remote sensing spectroradiometer data
2001年3月1日 · An inter-sensor comparison was also performed between the Ocean Optics spectroradiometer used in the laboratory, and the ASD spectroradiometer used in the field. The size of the ASD spectroradiometer FOV barrel made it impractical to obtain a full range of angular measurements in the laboratory necessary for panel BRF characterisation over a ...

2019年11月1日 · A field portable spectroradiometer (HR-1024 spectroradiometer, SVC Corp., New York, N.Y.) with the wavelengths from 350 to 2500 nm was used in this study. This photodiode spectroradiometer uses three diffraction grating spectrometers with one silicon (Si) (350–1000 nm) and two indium gallium arsenide (InGaAs) (1000–1850 nm, and 1850–2500 ...
Lever-arm and boresight correction, and field of view …
2019年9月1日 · The spectroradiometer FOV is estimated by determining the size of the spectroradiometer footprint for a known height above ground level (AGL). We apply the correction of the lever-arm and boresight on a flight dataset to demonstrate the improvement in pose estimation and subsequent footprint geolocation determination.
