摘要：

We used a system that exploits the Mach-Zehnder interferometer structure and Young's double-pinhole interference principle to measure the three-dimensional topographies of small objects at high precision. Next, we performed phase profilometry to measure small objects and achieve a height measurement within a 10 x 10-cm area. The accuracy of the measurement system improved by 44.1%, and the measurement time was reduced by 63.2%. (C) 2018 Society of Photo-Optical Instrumentation Engineers (SPIE)
