A Microlens Array Grating for Miniature Multi-Channel Spectrometers
Sensors, 2023 Most existing multi-channel spectrometers are constructed by physically stacking single-channel spectrometers, resulting in their large size, high weight, and limited number of channels. Therefore, their miniaturization is urgently needed. In this paper,
