The camera system's spectral range is split in several spectral channels, where each channel possesses its own imaging sensor. Such an optical setup is used, for example, in high-quality 3-sensor colour cameras. A 3-sensor camera is less vulnerable to laser dazzle than a single-sensor camera. However, the separation of the individual channels is not sufficient high enough to suppress crosstalk and thus all three channels will suffer from laser dazzling. To solve that problem, we suggest two different optical designs in which the spectral separation of the channels is significantly increased. The first optical design is a 3-channel camera system, which was already presented earlier. The second design is a 2-channel camera system based on optical multiband elements, which delivers undisturbed colour images even under laser dazzle.enlaser dazzlesensor protectioncomplementary wavelength bandstructural similarity index004670conference paper
