Multiphysics Modeling of a Novel Photoelastic Modulator for Ultra-High Performance FT Spectrometry

Abstract

We present the multiphysics model and simulation of a virtual stack/phased array (VSPA) photoelastic modulator (PEM), a novel type of high-retardation PEM for use in ultra-high performance FT spectrometers with applications in the optical recognition of explosives and CB warfare agents. The multiphysics model consists mainly of coupled partial differential equations (PDE) describing high-intensity acoustic fields driven by a phased array of attached piezoelectric transducers (PZT) and the coupled heat generation and flow driven by ultrasound absorption in the optical medium. A mixture of serial and parallel software is being used for modeling, simulation, and postprocessing. The software runs on a dedicated locally assembled PC cluster.
