Capturing images of moving objects with a moving illumination point source

摘要

An imaging system (1) for capturing images of moving objects (2) with minimal blurring by moving a point source(3) of illumination such that the position from which illumination is projected is changed as the object moves to ensure that the position of the image projected onto an imaging plane remains effectively stationary. The position from which illumination is projected functions as a point source of illumination. An image sensor (5) is positioned in the imaging plane and receives illumination that passes through the moving object. The image sensor produces a response to the received illumination. Because the image of the moving object remains effectively stationary on the image sensor, an image of the moving object can be constructed with minimal blurring and without having to halt the object, because it is not necessary to halt the object before capturing an image, the throughput of the imaging system is increased and the images are improved.
