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.
