To mass produce laser fuzes, it is necessary to quickly test various measurement parameters of the laser fuzes. It takes a long time to complete each test by using the routine method, which is difficult to mass produce laser fuze products. In order to obtain the measurement parameters of the field of view of receive and emitting quickly, for the laser fuze using the wide beam, this paper uses the laser fuze to receive and measure the field of view, obtained the data processing method according to the obtained test data. From the test data, the matching coefficient of the transmission and reception field of view can be calculated and derived the formula. The formula can be used to calculate the fuze action distance with the field of view distribution within the known target reflectivity and area. It can reduce the time consuming caused by the actual measurement. Through the experimental verification, it is found that the error between the actual measurement value and theoretical calculation value is small and can be considered to be basically the same. This calculation method can quickly calculate the action distance curve of each set of fuze window after testing the fuze transceiver component in the laboratory, which can avoid and reduce the trouble of physical testing.
