A laser detection method and apparatus for detection of laser beams can each perform operations for producing an interference image from detected light radiation, recording the interference image, and processing the recorded interference image in order to detect laser radiation. In order to allow more robust and faster laser detection, the apparatus and method can detect a spatially defined point distribution from the interference image and transform the point distribution such that a grid interval remains between a point grid in the point distribution, and a fixed position, which is independent of a position in the original image, is associated with the point grid. The apparatus and method can further detect a grid interval in the point grid that was transformed, and detect the position of the point grid from the point distribution by filtering with the assistance of the grid interval. |
