Raman spectroscopy is widely used to detect drugs, chemical leaks, food safety, explosive residue, and other fields. However, traditional Raman spectroscopy systems using visible or near-infrared light are greatly affected by environmental light. They typically require Raman spectroscopy in closed sample boxes or under nighttime conditions. Conventional UV Raman spectroscopy is mostly based on micro-distances and is difficult to adapt to the remote detection requirements of samples under natural light conditions.This paper designs and builds a UV Raman spectroscopy remote detection experimental system to meet the special remote Raman spectroscopy requirements under natural light environments. It comprises a 266 nm laser light source, front-end optical system, signal reception system, and signal processing system. The optical system design uses a coaxial semi-common optical system for the emission and collection of light paths, ensuring the systems focusing flexibility. It can quickly align and focus on distant substances for detection. The front-end optical system and signal reception system use relay lenses and fibers and are coupled with a blind UV spectrometer for transmission and detection of Raman spectroscopy signals, ensuring the systems overall flexibility. Based on iterative differential auto-regression estimation, the Raman spectroscopy denoising algorithm IDAR is used to denoise the detected Raman spectra, enhancing the resolution of weak Raman characteristic peaks in samples.The paper sets detection points at intervals of 100 mm from 200 to 1 500 mm. It conducts repeated multiple sets of Raman spectroscopy remote detection experiments on five typical substances: Teflon, sodium bicarbonate, calcium gluconate, erythromycin, and ibuprofen. The experiments are conducted at different integration times and distances, and the results are compared with those of a 15 mm micro-distance UV Raman spectroscopy detection system. The experimental results show that the remote detection system can effectively detect Teflon at a distance of 1 500 mm and achieve remote detection distances of 600mm for sodium bicarbonate, ibuprofen, calcium gluconate, and erythromycin samples. This proves that the blind UV Raman spectroscopy remote detection experimental system has good remote detection capabilities under natural light conditions and can meet the requirements of some on-site safety inspections, drug detection, explosive residue detection, and food safety inspection applications.
