Abstract :
A palm-sized optical measurement device capable of polarisation rotation and single-wavelength absorption measurements is presented. The device is equipped with a polarisation-analysing CMOS image sensor with an on-chip multi-angular polariser array. The volume of the device is as small as 51 cm3, which is smaller than both 1/1000 of a conventional desktop polarimeter and 1/10 of the previous device. The capability of the proposed device to perform simultaneous polarisation rotation/single-wavelength absorption measurements is experimentally verified through in situ monitoring of a photochemical reaction performed in a microflow reactor.
