CMOS sensor-based miniaturised in-line dual-functional optical analyser for high-speed, in situ chirality monitoring

A miniaturised in-line dual-functional optical analyser equipped with a polarisation-analysing CMOS image sensor was proposed and demonstrated. A single-wavelength optical absorption measurement function was also implemented in this device. The feasibility of the proposed device was demonstrated by evaluating two functions. Quasi-simultaneous optical rotation and absorption measurements were also performed. The results suggest that the present device is feasible as an in-line, in situ monitoring device for microchemical systems.
