New Concept: Reflectance Spectroscopy #361

Open tseccull opened 1 year ago

tseccull commented 1 year ago

Name the new concept Reflectance Spectroscopy

Describe the concept Spectroscopic observation of light reflected by an astronomical object. This technique is well established in observational studies of Solar System objects which reflect sunlight at optical and NIR wavelengths instead of emitting their own light. Reflectance spectroscopy is currently the primary method used to remotely sense the surface compositions of planetary bodies in the solar system, and is also a technique relevant to the study of exoplanets. Given that transmission spectroscopy is in the UAT, it seems apt to include reflectance spectroscopy, which is the inverse.

@ebortey Could you please find a definition from an authoritative source? If you have access to ScienceDirect, you may want to look at https://www-sciencedirect-com.ezp-prod1.hul.harvard.edu/topics/agricultural-and-biological-sciences/reflectance-spectroscopy.

A possible definition is: "Reflectance spectroscopy is an important method of measuring the absorption spectra and other properties of solids. Because this type of measurement can be made without contacting the sample, it is a powerful technique for the remote determination of the composition of soils and regoliths on the surfaces of bodies of the solar system, as well as powders in the laboratory."
