Mathematical model of the inline sensor based on matrix photodetector


The paper deals with the descriptiou of the method for the measurement of particle sizes using an inline sensor based on matrix photodetector. The case when the size of particles is smaller than the size of matrix sensor pixel is described. An analytical formula is proposed for particle size estimation depending on the charge accumulated by the pixel of CMOS matrix. The authors evaluate the sensitivity of the CMOS sensor at a given signal/noise ratio.
