Uncertainty principle for fringe signal detection is set up. Its application on the effect of signal length, phase measurement, and strain or slope measurement is discussed. The relationship between the accuracy and spatial resolution for measurand is investigated. Keywords Interferogram; Uncertainty principle; Spatial resolution; Accuracy
