Abstract
Low cost and compact 3D imaging for various applications like face-recognition, machine vision or LIDAR for automotive has introduced new requirements in terms of NIR light source characterization. These sources must comply safety regulations and must be verified rapidly and accurately during the fabrication process. In addition, precise characterization of the light source emissions within their entire angular aperture is mandatory to get accurate 3D images. The paper introduces a new Fourier optics system dedicated to this task.
