Abstract :
This paper introduces a novel E-SPART analyzer for the dust particle analysis for Mars mission. The new E-SPART analyzer is based on a stationary-fringe LDV which can simplify the system hardware composition and reduce both the physical size and weight of the system. The paper presents the new operational principle, the signal processing method and the algorithm. It also discusses the requirement of the size of sensing volume. Experimental results are given for the verification of the principle and algorithms.
