摘要： Method for detecting pulsed laser radiation having two-dimensional resolution of the direction of incidence with a CCD sensor having an imaging optic. Method includes generating, in signal processing having sampling frequency of at least 5 kHz, single images by comparing each pixel of CCD sensor to respective threshold values and by storing a pixel value exceeding the respective threshold value for an image processing, ascertaining, in the signal processing, a mean or peak value of stored pixel values of the single image pixel-by-pixel over at least 10 samples, forwarding a signal image obtained in signal processing for image processing at image frequency of 10 Hz to 500 Hz, and identifying from signal image, in an image processing, at least one signal pixel representing incident laser radiation. Method further includes determining direction of incidence of laser radiation from position of signal pixels on signal image.
