Abstract

We present a novel high-speed sensor for simultaneously measuring the three-dimensional (3D) shape and the surface temperature of fast moving objects. The 3D topography is obtained by a structured light sensor based on GOBO projection of aperiodic sinusoidal patterns in the visible range of light. At the same time, a high-speed long-wave infrared camera records the temperature distribution on the object surface. We show first promising 3D thermography measurement results of an inflating airbag, a basketball player, and the crushing of a metal tube conducted at a 3D frame rate of 1 kHz.
