Research output: Contribution to journalConference articlepeer-review


A shearing interferometer with a kitty-type self-pumped phase-conjugate mirror is proposed. The measurements of the focal length of a lens are demonstrated, with a standard deviation of 1.5%. In addition, the micro-displacement of several micrometers of a lens is measured with error less than 2%.
