Evanescent wave nano-velocimetry offers a unique three-dimensional measurement capability that allows for inferring tracer position distribution through the imaged particle intensities. Our previous study suggested that tracer polydispersity and failure to account for a near-wall tracer depletion layer would lead to compromised measurement accuracy. In this work, we report on a hybrid algorithm that converts the measured tracer intensities as a whole into their overall position distribution. The algorithm achieves a superior accuracy by using tracer size variation as a statistical analysis parameter.
