Hand-held MEMS hyperspectral imager for VNIR mobile applications

摘要

This paper presents a novel miniaturized hand-held hyperspectral imager for VNIR range of λ = 600 - 900 nm based on MEMS Fabry-Perot interferometer (MFP1) technology. In recent years, tunable MFPI optical filters have been utilized to demonstrate sensors for mobile applications, including CO2 smartphone sensor for mid infra-red region and hyperspectral iPhone for visible spectrum. This hand-held sensor module targets the VNIR range in order to enable food sensing, while utilizing low-cost camera technology to enable potential volume scalability for future sensing applications. The sensor module is wirelessly connected to a mobile device, which enables further application algorithms development and cloud-based solutions.
