摘要：
High-throughput on-line Raman detection has become commonplace in pharmaceutical and PAT. This has increased the demand for efficient, parallel spectral detection. In this work, a method of adjusting the optical structure parameters through multi-field theory is proposed to realize the detector accepting two spectral information from the light source at the same time. By combining two Raman probes and two customized Y-fibers, Raman spectra of two samples at the same laser power can be acquired simultaneously online. Compared with the multi-channel Raman spectroscopy detection system based on microscope device and multiple Raman spectroscopy coupling system, the measurement time and cost are greatly reduced. Thus, dual-channel Raman spectroscopy detection devices provide a cost and time-saving method for modern high-throughput on-line Raman detection.
