Abstract

We present hyperspectral imaging (HSI) systems based on a hyperchromatic confocal approach. Spatial filters are used to separate the spectral components of the light. The necessary multiplexing in time is realized by tuneable optics. In addition, we propose tunable systems with diffractive Alvarez-Lohmann lenses as well as fluidic micro lenses and present a demonstrator using Alvarez-Lohmann lenses. Micromechanical stepper actuators with large movement range are used to enhance the spatial resolution of those systems.
