Abstract: Abstract. We propose a differential laser Doppler velocimeter (LDV) for two-dimensional (2D) distribution measurements of the in-plane velocity component based on bias-frequency spatial encoding. Using two crossing beam arrays, the structure can effectively assign bias… read more here.

Abstract: This paper presents a method to measure the three-dimensional distribution of uniaxial stress based on Terahertz Time Domain Spectroscopy (THz-TDS). The measurement principle was first established, which combines the computed tomography (CT) method and the… read more here.
