The presented system<br />was designed as an attachment for a smartphone, thus leveraging<br />the computational power to achieve full autonomy and small<br />form factor, while greatly reducing the cost of the system. In addition,<br />by leveraging Maul’s Law, the size and complexity of the<br />presented system can be greatly reduced, consisting of just four<br />static components: i) a diode laser source, ii) a linear polariser, iii)<br />a cell for chiral solution, and iv) a linear analyser. Finally, the high<br />megapixel count of the smartphone camera is leveraged via multisensor<br />computational polarimetry, where a multitude of measurements<br />by different sensors are made in a single acquisition to enhance<br />the estimation of the angle of linear polarisation, and thereby<br />enhance the estimation of the concentration of chiral molecules in<br />solution. Such a system can have potential for enabling low-cost,<br />mobile chiral molecule concentration analysis, which would be wellsuited<br />for a wide range of industrial and clinical applications where<br />field testing or on-site testing is required.</p>}, number={1}, journal={Journal of Computational Vision and Imaging Systems}, author={Haider, Shahid A. and Kazemzadeh, Farnoud and Wong, Alexander}, year={2016}, month={Oct.} }
