ABSTRACT:
An information transmission system is provided for a guided missile 1 in which guidance information is transmitted from the missile launch point to the missile along a beam 8 of 10 .mu.m wavelength radiation. The missile has a rearwards facing optical system 9 to collect and focus the radiation onto a cooled cadmium mercury telluride detector. The proportion of cadmium to mercury in the detector is chosen so that just after launch in the early stage of detector cool-down the long wavelength cut-off of the detector just includes the 10 .mu.m radiation, providing an early guidance signal, and so that, as cooling proceeds, the long wavelength cut-off moves to longer wavelengths thereby rapidly enhancing the received signal to compensate for loss of received energy at the missile due to missile range increase.
