Raman signal with a high signal-to-noise ratio (SNR) under a strong sunlight environment of 30000∼60000 Lux is very hard to obtain. A compact remote Raman spectrometer (CRS) has been developed for the purpose of detecting diverse types of lunar and earth minerals. The system comprises a spectrometer that is equipped with an ICCD detector, a 30 mm entry pupil diameter beam expander, and a 532 nm Nd: YAG Q-switched laser serving as the source of Raman scattering. The implementation of synchronous trigger and gating technology effectively overcomes the impact of strong sunlight. We obtained Raman spectra using a shorter integration time than in previous studies. The experimental results demonstrate that the detection of remote Raman spectroscopy under intense sunlight conditions facilitates the identification of silicates that have been discovered on the moon. © 2023 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.
