Abstract

According to the characteristics of new laser fuze optical transmitter which emits 90°×2° linear infrared laser beam, measurement technique on transmitter optic component is researched. New laser fuze optical transmitter test system is developed, and a method based on two linear array CCD scanning imaging is proposed. The twolinear array CCDs are placed at Z1, Z2 positions and are separated by an angle Φ. Near field and far field light beam distribution are acquired to realize the automatic measurement of parameters such as the view direction relative intensity distribution, beam divergence angle, pitch angle and optical power by beam analysis software. Experimental measurement results indicate that the parameter measurement values are in the acceptable range with measurement accuracy of 1′, repeatability precision of ≤5%. The system performance is well in repetition, dependability and automatization.
