Smart multispectral imager for industrial applications

Abstract

After the big impact of optical 3D-imaging processing, multi- and hyperspectral imaging solutions will be the next technological innovation in image processing for industrial application. This work presents a clever and affordable solution for multispectral imaging: a smart imager for measurements spanning 400 nm to 950 nm in a 50 nm step with 50 nm bandwidth. With a combination of industrial interface technology (GigE-Vision), new CMOS-imaging sensors as well as new approaches for the active compensation of chromatic aberration novel applications are possible. The core idea of the smart multispectral sensor is to support of such features, while giving the user a friendly interface. This manuscript is organised as follows: firstly, a compact overview on history, spectral imaging and smart cameras is presented. The introduction is shortly followed by a brief description of the state of the art. The system is meticulously presented in the four subsequent sections. System evaluation shows some specific applications and a conclusion closes this work.
