ʻOi aku ka mānoanoa a me ka liʻiliʻi o nā lens Optical; He lahilahi a nui ka nui o nā lens Fresnel.
ʻO ke kumu o ka lens Fresnel he physicist Farani ʻo Augustine. Ua hana ʻia e AugustinFresnel, nāna i hoʻololi i nā lens spherical a me aspherical i mau lens planar māmā a lahilahi e hoʻokō i ka hopena optical like. A laila, ua hana ʻia ka nui o nā pūnaʻi optical ma ka ʻili planar ma o ka hana ultra-precision, a ua pāʻani kēlā me kēia hui i ke kuleana o kahi lens kūʻokoʻa. ʻO ka lens Fresnel ke ala maikaʻi loa e ʻike ai i ka lens nui, pālahalaha a lahilahi.
ʻO ka hana ʻana i nā lens Feist Fresnel, ʻoi aku ka nui o nā lens nui, e pili ana i ka simulation hoʻolālā optical, ka ʻenehana hana ultra-precision, nā mea polymer a me ke kaʻina hana hoʻoheheʻe pololei. Hiki ke hoʻohana nui ʻia ka lens Fresnel i nā kukui, hoʻokele, noiʻi ʻepekema a pēlā aku.
ʻO ka lens Fresnel kahi ʻano pāpaʻi pālahalaha e hōʻike a hoʻopaʻa i nā kukuna. Ke hoʻohana nei i kēia kumumanaʻo a me ka ʻenehana splicing, hiki iā mākou ke hoʻololi i ka paraboloid, ellipsoid a me ke kiʻekiʻe kiʻekiʻe o ka lens optical surface o kekahi aperture i loko o ke ʻano mokulele, i ʻike ai i ka splicing Fresnel lens o kēlā me kēia nui, a e ʻimi i ka noi o ka ikehu lā a me ka reflector nunui (pēlā. like me guizhou Tianyan 500-mika aperture radio telescope).
Hiki ke hoʻohana ʻia ka ʻenehana Mosaic pau ʻole o Fresnel lens mai kekahi mau mika, a i nā haneli mau mika, a i kekahi nui nui. Hiki iā Guizhou Tianjia parabolic reflection surface me ke anawaena o 500 mika ke hoʻohana i kēia ʻenehana Mosaic e hoʻohālikelike i ka parabolic surface me ka lens Fresnel flat, e hōʻemi ana i ka paʻakikī o ka hana ʻana a ʻoi aku ka maʻalahi o ka hoʻouka a hoʻoponopono.
