Pipeline for the development of compact BRS-based CGM. (a) Strategy development pipeline. (b) Measured full-spectrum Raman signal of individual components and modeled tissue phantom signals: PBS (blue line), 20% intralipid solution in water (green line); 20% glucose solution in water (red line); simulated no-glucose tissue phantom (black line); simulated high-glucose tissue phantom (pink line). (c) Scheme of the optical system for BRS. HS: heat sink; TEC: temperature control; D-M: D-shaped mirror; BB: beam blocker; LLF: laser line filter; AD: achromatic doublet; LPF: long-pass filter; BPF: band-pass filter; APD: amplified photodiode; PD: photodiode (d) Simulated Raman spectra around the Raman peak of glucose at 1125 cm–1 through 11 glucose levels. Shear areas indicate the chosen bands for BRS.
