Though shot noise is theoretically unavoidable, it is possible to make this less of a problem by increasing the quantum efficiency of the imager. We have developed a HARP film doped with a large amount of tellurium to increase the quantum efficiency for the green incident light that has a great influence on the picture qualty of the color TV camera. Our evaluation of this new film shows that the quantum efficiency at a wavelength of 540 nm is double that of conventional film and the shot noise is reduced by 3 dB.
