Abstract: A space control system and a detection system are disclosed. The detection system is configured for distinguishing a moving living object, e.g. a human being, from a moving machine object in a space. The system comprises an imaging apparatus configured for producing a plurality of images over time of at least a part of the space. The images have a good spatial resolution. The system also comprises a processor configured for determining motion signals of the moving living object and the moving machine object from the plurality of images. The processor is configured to transform the motion signals to a frequency domain and distinguish in the frequency domain between motion signals related to moving living objects and motion signals related to the moving machine objects. Accordingly, the system is enabled to detect at least one of the living object and the machine object in the part of the space on the basis of the distinguished motion signals.

Abstract: A defect inspection system is provided for inspection of defects in the surface of a sample. An array of light sources is used, with different light sources providing light to the sample from different directions. A main direction of illumination is defined with highest intensity, and this direction evolves over time. By providing varying directional illumination instead of blanket illumination, it becomes easier to detect defects.
