Angular response of sensors
Description
A collection of angular response data for selected broadband sensors used for measuring ultraviolet and visible radiation and of cosine diffusers used with spectrometers. Each data frame in the collection contains three variables, angle.deg (degrees) at either regular or irregular intervals, response relative to the maximum (as a fraction of one) and response relative to a perfect cosine response (as a fraction of one). Data are either from manufacturer specifications or independent measurements reported in the scientific literature.
Usage
diffusers.lst
Format
A response_mspct object containing a
response_spct objects as named members.
Each member spectrum contains three variables:
angle.deg (degrees)
response (/1)
response.over.cosine (/1)
Note
Values are only good as reference, as individual sensors and diffusers deviate to a smaller or larger extent from typical or mean responses for their type. Variability is also reflected in some cases as an asymmetry in opposite angles away from the vertical.
