Practical Calibration of Optical Spectrometers for Field Measurements.

Abstract

The calibration objectives of spectrometric, photometric, and radiometric instruments for field measurements are given. The instrumental optical properties which are to be ascertained are: (1) background noise levels, (2) field of view, (3) frequency response, (4) absolute spectral scan position, (5) optical resolution, (6) relative spectral response, (7) absolute responsivity, (8) spectral purity. The important technical definitions, meanings and relationships are given. The special considerations and practical limitations encountered are discussed, as appropriate, in each of four regions of the electromagnetic spectrum. These wavelength ranges of interest are categorized as UV (1800 to 4000 A), visible (4000 to 10,000 A), SWIR (1 to 5 micrometers and LWIR (5 to 25 micrometers) according to the optical detector properties and operating requirements which are distinct in each region.
