Abstract
Laser dazzling of electro-optical sensors states a serious problem. Especially when navigational tasks shall be fulfilled a disturbance of the sight is inacceptable. Classical protection measures like e.g. laser safety filters usually lack of the drawback of color distortion and a considerable loss in transmission. Therefore, new protection concepts should be aspired which are independent of the laser wavelength and do not affect the vision. In this paper we discuss a novel concept to protect electro-optical sensors against laser dazzling based on spatial light modulator technology and wavelength multiplexing. In particular, the method is suited as a protection measure against continuous wave laser sources.
