He mea koʻikoʻi nā ʻano hana optical analytical i ke kaiāulu hou no ka mea e ʻae lākou i ka ʻike wikiwiki a palekana o nā mea i loko o nā mea paʻa, wai a me nā kinoea.Ke hilinaʻi nei kēia mau ʻano i ka launa pū ʻana o ka māmā me kēia mau mea ma nā ʻāpana like ʻole o ka spectrum.No ka laʻana, loaʻa i ka spectrum ultraviolet ke komo pololei i nā hoʻololi uila i loko o kahi mea, ʻoiai ʻo terahertz e maʻalahi loa i nā haʻalulu molekala.
He kiʻi noʻeau o ka waena waena infrared pulse spectrum ma ke kua o ke kahua uila e hoʻopuka ai i ka pulse
Nui nā ʻenehana i hoʻomohala ʻia i nā makahiki i hiki ai i ka hyperspectroscopy a me ke kiʻi kiʻi, e ʻae i nā ʻepekema e nānā i nā ʻano like ʻole e like me ke ʻano o nā molekala i ko lākou pelu ʻana, wili a haʻalulu paha i mea e hoʻomaopopo ai i nā hōʻailona maʻi kanesa, nā kinoea ʻōmaʻomaʻo, nā mea haumia, a me nā mea ʻino.Ua hōʻoia ʻia kēia mau ʻenehana ultrasensitive i nā wahi e like me ka ʻike ʻana i ka meaʻai, biochemical sensing, a me ka hoʻoilina moʻomeheu, a hiki ke hoʻohana ʻia e aʻo i ke ʻano o nā mea kahiko, nā kiʻi pena, a i ʻole nā mea kiʻi kiʻi.
ʻO kahi luʻi lōʻihi ʻo ia ka nele o nā kumu kukui paʻa e hiki ke uhi i kahi ākea spectral nui a lawa ka mālamalama.Hiki i nā Synchrotrons ke hāʻawi i ka uhi spectral, akā ʻaʻole lākou i ka coherence kino o nā lasers, a hiki ke hoʻohana ʻia nā kumu kukui i nā mea hoʻohana nui.
Ma kahi noiʻi hou i paʻi ʻia ma Nature Photonics, he hui honua o nā mea noiʻi mai ka Spanish Institute of Photonic Science, ka Max Planck Institute for Optical Science, Kuban State University, a me ka Max Born Institute for Nlinear Optics and Ultrafast Spectroscopy, i waena o nā mea ʻē aʻe. he kumu hoʻokele paʻa, ʻōlinolino kiʻekiʻe waena-infrared.Hoʻohui ʻo ia i kahi aniani anti-resonant ring photonic crystal fiber me kahi aniani nonlinear novel.Hāʻawi ka hāmeʻa i kahi kikoʻī koʻikoʻi mai 340 nm a 40,000 nm me kahi kukui spectral ʻelua a ʻelima mau kauoha o ka nui ma mua o kekahi o nā mea hana synchrotron māmā loa.
E hoʻohana ana nā haʻawina i ka wā e hiki mai ana i ka manawa pulse manawa haʻahaʻa o ke kumu kukui e hana i ka nānā ʻana i ka manawa-domain o nā mea a me nā mea waiwai, e wehe ana i nā ala hou no nā ʻano ana multimodal i nā wahi e like me ka spectroscopy molecular, kemika kino a i ʻole ka physics mokuʻāina, wahi a nā mea noiʻi.
