Industrial Applications

Due to their extremely high acquisition speeds and real-time image correction features, the HySpex cameras are well suited for a wide variety of industrial applications such as material inspection or quality control.
 

In a typical industrial application, the HySpex camera is mounted statically above a conveyor belt using the belt motion for scanning.
 

Using the VNIR-1024 and 1 meter working distance as an example; the field of view is ~28 cm and the pixel footprint on the conveyor belt is 0.27 mm x 0.56 mm. With these settings and full spectral range and resolution, the maximum speed of the conveyor belt is 46 cm/s. The belt speed can be drastically increased if rectangular pixels are permissible, or by reducing the spatial/spectral resolution.
