摘要

We propose a quantitative approach toward the detection of collimation of a coherent optical beam. For detection of collimation position of the collimator, a temporal phase shifting technique has been incorporated into Talbot interferometry The slope of the phase maps depicts the collimation position of the collimator. This technique offers high precision, accuracy, and provides automated output.
