Description

Abstract: Microelectromechanical systems (MEMS) are of great interest for applications that require field-portability due to their small size, weight, power and cost (SWP+C). Similarly, MEMS-based Fabry–Pérot filters (FPFs) are of great interest for developing micro-spectrometers for numerous remote-sensing spectroscopy and imaging applications, thereby overcoming the non-portability drawback of conventional spectrometers. Since MEMS-based FPFs use an electrical tuning mechanism to scan over a range of wavelengths, it is critical to examine their switching accuracy to ensure a stable response over the lifetime of these devices. In this study, we examine the switching behaviours of a MEMS-based FPF over 6 million switching cycles to understand the reliability in peak wavelength over an extended period of use.
