AB - In this work, we present a calibration procedure of a multispectral snapshot camera, which is based on a multi-aperture system approach combined with a slanted linear variable spectral filter. The ultra-compact multispectral imaging system exploits state of the art micro-optical manufacturing techniques on wafer-level, which leads to a size of only 60  60 28 mm3. The setup enables the single-shot acquisition of 66 spectral channels with a linear spectral sampling over an extended wavelength range of 450-850 nm and a spatial sampling of 400400 pixels per channel at a large field of view of 68. In particular, we propose a spectral and spatial calibration procedure in order to extract hyperspectral data cubes from the acquired raw image and further, to analyze characteristic system parameters. Finally, we demonstrate the systems capabilities for advanced object classification using characteristic spectral indices by utilizing a customized multispectral analysis.
