| These tutorials are intended to provide basic information about how measurements are made with interferometers, transmissometers and reflectometers. They are not purported to be thorough mathematical analyses since there are plenty of excellent tutorials on the internet which do that very well. We just want to explain some of the little terms and factors that individuals new to the technology might find confusing. |
