Abstract: An interference measurement system self-alignment method, which can be realized through an optical image interference measurement system. The method comprises the following steps of: utilizing the imaging device to get the optical information of the object to be measured and store the optical information thus obtained; performing the inclination adjustment of the first direction rotation axis of the object platform based on the direction of the interference fringe in the optical information until the interference fringes are adjusted to a defined orthogonal direction, thus eliminating the inclination of the first direction rotation axis; and performing the inclination adjustment of the second direction rotation axis of the object platform based on the expansion direction of the interference fringe in the optical information until the spacing of the interference fringes are adjusted to the maximum, thus eliminating the inclination of the second direction rotation axis.

Abstract: A pre-interception device includes an input portion for a fluid to flow in, an output portion for the fluid to flow out, a plurality of diversion flow channels and a plurality of interception portions. Each diversion flow channel is in communication with the output portion and the input portion, is configured to provide turning guidance for flow of the fluid, and has a fluid lift section. The interception portions are configured to form a turbulent flow field in the fluid. The turbulent flow field can have foreign objects flowing through the diversion flow channel be captured. Accordingly, a filtering effect is achieved based on physical properties of the foreign objects. When the pre-interception device is additionally combined with a filter net to form a filtering system, the burden on the filter net is further alleviated, hence extending a service life of the filter net and reducing costs.
