He mea nui 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, nā wai a i ʻole nā kinoea. Hilinaʻi kēia mau ʻano hana i ka mālamalama e launa pū ana 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 he mea maʻalahi loa ia i nā haʻalulu molekala.
He kiʻi noʻeau o ka spectrum pulse mid-infrared ma ke kua o ke kahua uila e hoʻopuka ana i ka pulse
Ua hiki i nā ʻenehana he nui i hoʻomohala ʻia i nā makahiki i hala aku nei ke hana i ka hyperspectroscopy a me ke kiʻi ʻana, e ʻae ana i nā ʻepekema e nānā i nā hanana e like me ke ʻano o nā molekala i ko lākou pelu ʻana, milo ʻana a haʻalulu paha i mea e hoʻomaopopo ai i nā māka maʻi kanesa, nā kinoea ʻōmaʻomaʻo, nā mea haumia, a me nā mea ʻino. Ua hōʻoia ʻia kēia mau ʻenehana ultrasensitive he pono i nā wahi e like me ka ʻike ʻana i ka meaʻai, ka ʻike biochemical, 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 kālai ʻia.
ʻO kahi pilikia lōʻihi ka nele o nā kumu kukui liʻiliʻi i hiki ke uhi i kēlā ʻano laulā spectral nui a me ka lawa ʻana o ka mālamalama. Hiki i nā Synchrotrons ke hāʻawi i ka uhi spectral, akā nele lākou i ka pilina manawa o nā lasers, a hiki ke hoʻohana ʻia kēlā mau kumu kukui i nā hale hoʻohana nui wale nō.
Ma kahi noiʻi i paʻi ʻia ma Nature Photonics, ua hōʻike kahi hui noiʻi honua mai ka Spanish Institute of Photonic Sciences, ka Max Planck Institute for Optical Sciences, Kuban State University, a me ka Max Born Institute for Nonlinear Optics and Ultrafast Spectroscopy, a me nā mea ʻē aʻe, i kahi kumu hoʻokele mid-infrared compact, high-brightness. Hoʻohui ia i kahi fiber crystal photonic inflatable anti-resonant ring me kahi crystal nonlinear hou. Hāʻawi ka hāmeʻa i kahi spectrum coherent mai 340 nm a i 40,000 nm me ka ʻōlinolino spectral ʻelua a ʻelima mau kauoha o ka nui kiʻekiʻe ma mua o kekahi o nā hāmeʻa synchrotron ʻōlinolino loa.
E hoʻohana nā haʻawina e hiki mai ana i ka lōʻihi o ka pulse manawa haʻahaʻa o ke kumu kukui e hana i ka nānā ʻana i ka manawa o nā mea a me nā mea hana, e wehe ana i nā ala hou no nā ʻano ana multimodal ma nā wahi e like me ka spectroscopy molecular, ke kemika kino a i ʻole ka physics mokuʻāina paʻa, wahi a nā mea noiʻi.
