| Abstract | ||
| The aim of this research is decreasing the effect of atmosphere scattering on receiving rays from the detector by using a metal cavity that has special specification by putting the detector inside it in a limited distances , this hood is decrease the field of view (F O V) Of detector also reducing the solid angle of receiving rays which is function of the utilized detector area and whole hood. to increase the efficiency of the system working, the different optical filters have been used, it will produce best detection for received rays depending on many parameters such; transmission(T%), detectivity(D*,D**), detector area, detector geometric field of view, input optical filter bandwidth and the ability of recognize the weak signals by connected it to electronic circuits. | ||
