Novel spectral resolution enhancement techniques for widespread multi-channel spectrometers
This article describes a novel spectral resolution enhancement technique for widespread multi-channel spectrometers, while maintaining their attractive advantages such as high-speed measurement, compactness, low-cost, and robustness. It aims to inexpensively provide a high performance spectrometer that can be used under various environments of diversifying needs in future applications like IoT. The well-known Vernier based technique enables the providing of superior spectral resolution performance in a multi-channel spectrometer through a simple change of the system arrangement and represents a critical step towards low-cost real-time spectral monitoring of dynamic events in various situations in our daily lives.
