New multiplexed system for synchronous measurement of out-of-plane deformation and two orthogonal slopes
文献摘要：
We propose a novel system for synchronous measurement of out-of-plane deformation and two orthogonal slopes using a single camera.The linearly polarized reference beam introduced by an optical fiber interferes with the unpolarized object beam to measure the out-of-plane deformation.A modified Mach-Zehnder interferometer is used to measure the two orthogonal slopes of the out-of-plane deformation.One of the object beams of the Mach-Zehnder interferometer is an unpolarized beam,and the other object beam is split into two orthogonal linearly polarized object beams by a polarizing prism.The two beams are orthogonally polarized.Hence,they will not interfere with each other.The two polarized beams respectively interfere with the unpolarized beam to simultaneously measure the two orthogonal slopes of the out-of-plane deformation.In addition,the imaging lens and apertures are respectively placed in three optical paths to independently control the carrier frequencies and shearing amounts.The effectiveness of this method can be proved by measuring two pressure-loaded circular plates.
