A collection of response spectra for various image sensors and digital cameras responsive to ultraviolet, visible, NIR and/or SWIR radiation. Each spectrum in the collection contains two variables, wavelengths (nm) at irregular intervals and spectral responsiveness (in photon units = quantum efficiency). Spectral data are normalized to one at the wavelength of maximum quantum efficiency only when this is how the original source published the data.
Format
A response_mspct object containing
response_spct objects as named members.
Spectral objects for monochrome image sensors contain two numeric variables, with quantum efficiency in some cases in relative energy units:
w.length (nm)
s.q.response (r.u.)
Spectral objects for colour image sensors contain the spectra in long form with two numeric variables, and in addition a factor with channel ids:
w.length (nm)
s.q.response (r.u.)
channel (factor with names as levels)
The spectral objects contain, in addition to the spectral data, metadata
stored in R attributes sensor.properties, what.measured,
how.measured, and comment.
