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