Particle sizing of colloidal suspensions by low-coherence fiber optic dynamic light scattering

► We present a particle sizing technique combining low-coherence interferometry and FODLS. ► The temporal electric field autocorrelation function of singly scattered light can be measured. ► We can estimate the particle size in a broad volume fraction range use CONTIN method. ► The particle size can be obtained with the accuracy 5% in the volume fraction range from 0.01 to 0.1.
