Abstract

In modern street battle, counter-sniper operations have become the main issue. However, due to the strong unidirectionality of laser beam, it is necessary to shape the laser beam to became useful. At the same time, in order to improve the detection efficiency, the energy of the laser beam is required to be as concentrated as possible, and the detection range is as wide as possible. Therefore, for meeting the requirements, comparing cylindrical with free-form surface prism on the shaping affection The result shows best shaping effect is achieved by using the free-form surface prism. In order to ensure that the laser energy loss is small, the manufracturing processing of freeform prism is analyzed. PSD(power spectral density) characteristics of the optical element surface and its influencing factors are discussed. So as to achieve the laser detection efficiency and detection distance requirements.
