Xiang Caixin, Xiang Yang . The System Error of the Collimating Lens in Unequal-path Twyman Interferometer[J]. Editorial Office of Optics and Precision Engineering, 1989,(1): 22-24DOI:
We discuss the system error of the collimating lens in the unequal-path Twyman interferometer from the point of view of the wavefront deformed travel. The system error of the collimating lens is propertional to the difference between the two optical arm-lengths in the interferom-eter and to the square of the wave aberration of the collimating lens.
