Embodiment Construction

[0032] The embodiment and accompanying drawing of Maxwell micro-hemispheric array reflector of the present invention are as follows in detail:

[0033] Fig. 4a is a schematic diagram of the optical path of a single ideal Maxwell micro-hemispherical reflector of the present invention when the light beam is vertically incident. According to the principle of Maxwell lens, when the refractive index distribution of the hemispherical lens is as formula (1), parallel light is incident on the flat end surface of the hemispherical lens, and is sharply focused on the rear hemispherical surface of the hemispherical lens after being refracted by the lens.

Abstract

A Maxwell micro-half ball array reflector is prepared by using ion exchange technique to work out half ball lens with reflectivity distribution of Maxwell lens, plating high reflection film at back surface of half ball and imbedding on binding layer combined with sticking layer, and sticking them on carrier in different form for forming various array reflectors.

Description

technical field [0001] The invention belongs to the field of target tracking and instrument technology, in particular to a Maxwell micro-hemispheric array reflector with high retroreflection rate, large incident angle and directional retroreflection characteristics. Background technique [0002] Retroreflective cooperative targets are widely used in laser detection, satellite ranging, space docking, and tracking measurement systems. The retroreflective characteristics of cooperative targets seriously affect the range, measurement accuracy and tracking accuracy of the detection system. Traditional retroreflective cooperation targets mainly include corner cube reflectors, "cat's eye" reflectors and microarray reflectors composed of corresponding reflectors. [0003] The corner cube prism array reflector shown in Figure 1 relies on the total reflection of three right-angled surfaces of a single corner cube reflector to achieve retroreflection, and can only form retroreflection ...
