Abstract
An asymmetric optical interferometry method, comprises the following steps: an incident light is split into two beams, and the two beams are respectively projected onto a surface of an object to be tested and a reference mirror; and then respectively pass through a first imaging lens having a larger area on the side of the object, and a second imaging lens having a smaller area on the side of the reference mirror, and overlap on a photoelectric sensor after passing through a third imaging lens to form at least one interference image (S); the corresponding interference image is input into a computer to obtain a signal of the corresponding interference image (S); parse the signal of the corresponding interference image to obtain a three-dimensional shape (S) of the surface of the object. Also provide an asymmetric optical interferometry device.
