Abstract

A measurement technique capable of recording three-dimensional laser induced images with a spatial resolution of 610x512x20 voxels over a volume of 29x24x15 mm(3) and at a frame rate of 1 kHz is presented. A novel approach for sweeping the illuminating laser sheet across the investigated volume is introduced as a key feature. The technique is applied to imaging nebulized water droplets with a nitrogen-jet central feature.

摘要

本文介绍了一种测量技术，该技术能够在29×24×15立方毫米的体积上，以1千赫的帧率记录三维激光诱导图像，其空间分辨率为610×512×20体素。作为一项关键特性，引入了一种将照明激光片扫过被研究体积的新方法。该技术应用于对具有氮气喷射中心特征的雾化水滴进行成像。
