An appropriate method for mutual occlusion is essential to provide a decent user experience in many application scenarios of augmented reality (AR). However, existing mutual occlusion methods fail to work well with a large field of view (FOV). In this paper, we propose a double-parabolic-mirror (DPM) structure that renders hard-edge occlusion within a wide FOV. The parabolic mirror increases the numerical aperture of the system significantly, and the usage of paired parabolic mirrors eliminates most optical aberrations. A liquid crystal on silicon (LCoS) device is introduced as the spatial light modulator (SLM) for imaging a bright see-through view and rendering sharp occlusion patterns. A loop structure is built to eliminate vertical parallax. The system is designed to obtain a maximum monocular FOV of H114\u00b0 x V95\u00b0 with hard-edge occlusion and a FOV of H83.5\u00b0 x V53.1\u00b0 is demonstrated with our benchtop prototype.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" class=\"alignnone size-full wp-image-2654\" src=\"https:\/\/carelab.info\/wp-content\/uploads\/2021\/08\/Yan_OL_Paper_2.jpg\" alt=\"\" width=\"1076\" height=\"913\" srcset=\"https:\/\/carelab.info\/wp-content\/uploads\/2021\/08\/Yan_OL_Paper_2.jpg 1076w, https:\/\/carelab.info\/wp-content\/uploads\/2021\/08\/Yan_OL_Paper_2-300x255.jpg 300w, https:\/\/carelab.info\/wp-content\/uploads\/2021\/08\/Yan_OL_Paper_2-768x652.jpg 768w\" sizes=\"(max-width: 1076px) 100vw, 1076px\" \/><\/p>\n<p>(A) \u5165\u5c04\u77b3\u306e\u4f4d\u7f6e\u304b\u3089\u8a66\u4f5c\u30b7\u30b9\u30c6\u30e0\u3092\u7d4c\u305a\u306b\u64ae\u5f71\u3057\u305f\u5b9f\u74b0\u5883\u306e\u69d8\u5b50\uff0e(B) \u8a66\u4f5c\u30b7\u30b9\u30c6\u30e0\u3092\u7d4c\u305f\u5b9f\u74b0\u5883\u306e\u69d8\u5b50\uff0e(C) \u30bf\u30fc\u30b2\u30c3\u30c8\u753b\u50cf\uff08\u8d64\u3044\u30c6\u30a3\u30fc\u30dd\u30c3\u30c8\uff09\uff0e\u660e\u90e8\u3068\u6697\u90e8\u3092\u9752\u3068\u9ec4\u8272\u306e\u7834\u7dda\u3067\u793a\u3059\uff0e(D) \u906e\u853d\u30d1\u30bf\u30f3\u306a\u3057\u3067\u8868\u793a\u3057\u305f\u30bf\u30fc\u30b2\u30c3\u30c8\u753b\u50cf\uff0e(E) LCoS\u3067\u751f\u6210\u3057\u305f\u906e\u853d\u30d1\u30bf\u30f3\uff0e(F) \u906e\u853d\u30d1\u30bf\u30f3\u3042\u308a\u3067\u8868\u793a\u3057\u305f\u30bf\u30fc\u30b2\u30c3\u30c8\u753b\u50cf\uff0e\u30c6\u30a3\u30fc\u30dd\u30c3\u30c8\u306e\u8996\u8a8d\u6027\u3068\u30ea\u30a2\u30ea\u30c6\u30a3\u306e\u5411\u4e0a\u3092\u78ba\u8a8d\u3067\u304d\u308b\uff0e<\/p>","protected":false},"excerpt":{"rendered":"<p>Zhang Yan\u541b(D3)\u306e\u8ad6\u6587\u304cOptics Letters\u306b\u63a1\u9332\u3055\u308c\u307e\u3057\u305f <a class=\"more-link\" href=\"https:\/\/carelab.info\/ja\/2021\/07\/26\/zhang-yans-paper-has-been-accepted-to-optics-letters\/\">More &#8230;<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"pgc_meta":""},"categories":[1],"tags":[],"aioseo_notices":[],"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/posts\/2645"}],"collection":[{"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/comments?post=2645"}],"version-history":[{"count":11,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/posts\/2645\/revisions"}],"predecessor-version":[{"id":2674,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/posts\/2645\/revisions\/2674"}],"wp:attachment":[{"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/media?parent=2645"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/categories?post=2645"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/tags?post=2645"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
