Abstract

This paper introduced the structure features of such supersonic jet system, and described the step scan method and the rapid scan method of data acquisition system based on Labview software platform. A small section spectrum of bending vibration band of the complex Ar-N₂O and Ne-N₂O were measured using this improved device. This letter also analyzed the detailed spectral characteristics of the pinnozzle and the slit jet, and validated the Lambert-Beer Law between the absorption optical path and spectrum intensity.
