E-SPART Analyzer Based on a Stationary-Fringe LDV

This paper introduces a novel E-SPART analyzer for the dust particle analysis for Mars mission. The E-SPART analyzer is based on a stationary-fringe LDV (laser Doppler velocimeter) which can simplify the system hardware composition and reduce both the physical size and weight of the system. The paper presents the operating principle, the signal processing method and the algorithm. Experimental results are provided to confirm the effectiveness of the principle and algorithms
