A kind of four spectral timedelayintegrated charge coupled device (TDI CCD) is designed and fabricated by integrating four TDICCDs on one chip. Different narrowband filter films are plated on the corresponding positions of the light window to realize multiband light splitting. For the designed TDICCD, its pixel size is 28μm×28μm, the horizontal pixel size is 3072 elements, the line frequency is 10kHz, the charge transfer efficiency is 0.99999, the saturation output voltage is 2650mV, the antiblooming ability is more than 100×, and the dynamic range is 7143∶1.
