The results of optical guidance of flowing particles to the probe volume of Dual-Beam Velocimetry

Amin Mousavi et al.

Summary: This study investigates a new method for measuring the size and condensation of microscopic particles using dual beam methods, which is shown to significantly increase the Signal-to-Noise Ratio and the number of detected photons scattered from the particles, while also reducing Doppler frequency broadening and angular uncertainty. The condensation of aerosols in the lab was measured by counting signal bursts from particles passing through light fringes after being guided into a single charge Bessel-Gaussian laser beam. Due to the lack of laboratory facilities, the frequency Doppler shift of the laser beam to determine the particle's dimensions could not be determined.
