Abstract

The mathematical properties of the arctangent function are investigated, revealing the mechanism of error propagation in digital phase-shifting applications. The analysis gives a systematic approach to the assessment of errors and, as such, provides a valuable tool for understanding the propagation of errors in any phase-shifting algorithm.
