He aha ʻo Terahertz? Ke hoʻomaopopo nei i nā hana o Terahertz

ʻO ka radiation Terahertz (THz), i kapa pinepine ʻia ʻo "terahertz gap," aia i kahi kūlana kūikawā ma ka spectrum electromagnetic, e waiho ana ma waena o nā microwaves a me ka radiation infrared. ʻO ka maʻamau, aia kēia hui i ke alapine (frequency) mai 0.1 a 10 terahertz a ma ka nalu mai 3 millimeters a i 30 micrometers. Akā he aha maoli ka terahertz? A he aha kāna kuleana ma nā ʻano like ʻole?

ʻAʻole wale ka radiation Terahertz he mea hou i ka ʻepekema; ​​he mau noi kūpono kona ma nā ʻano he nui. ʻO kekahi o kāna mau hana koʻikoʻi ka imaging a me ka spectroscopy. Hiki i ke kiʻi Terahertz ke komo i loko o nā ʻano mea like ʻole, e lilo ia i mea waiwai nui ma nā wahi e like me ka nānā palekana, ka hoʻāʻo ʻole e luku, a me ke kiʻi biomedical. No ka laʻana, hiki iā ia ke ʻike i nā mea kaua huna a i ʻole nā ​​​​mea pahū me ka ʻole o nā hopena maikaʻi ʻole o nā X-ray.

Ma ke kahua o ke kelepona ʻana, ke noiʻi ʻia nei ka ʻenehana terahertz no ka hoʻoili ʻikepili wikiwiki. I ka ulu ʻana o ke koi no ka wikiwiki o ka pūnaewele, ke noiʻi nei nā kānaka noiʻi i ka hiki o nā nalu terahertz ke hoʻoili i ka ʻikepili ma nā wikiwiki i manaʻo ʻole ʻia. Hoʻohiki kēia e hoʻololi i ke kamaʻilio uea ʻole, e hiki ai ke hoʻoiho wikiwiki a hoʻomaikaʻi i ka pilina.

Eia kekahi, he kuleana koʻikoʻi ko ka ʻenehana terahertz i ke ʻano o nā mea. Ma ka nānā ʻana i ka pane terahertz o nā mea, hiki i nā kānaka ʻepekema ke loaʻa ka ʻike hohonu i ko lākou mau waiwai, e like me ke conductivity a me ka haku mele. He mea nui loa kēia i ka ʻoihana lāʻau lapaʻau, no ka mea, kōkua ka spectroscopy terahertz i ka kaohi ʻana i ka maikaʻi o ka lāʻau.

I ka hopena, he kahua noiʻi hoihoi ka radiation terahertz me nā manaʻolana noi ākea. Mai ka hoʻomaikaʻi ʻana i nā hana palekana a hiki i ka hoʻokele wikiwiki ʻana i nā kamaʻilio a me ka hoʻomaikaʻi ʻana i ka nānā ʻana i nā mea, he nui nā noi kūpono o ka ʻenehana terahertz. Ke hoʻomau nei ka noiʻi, hiki iā mākou ke manaʻo e ʻike i nā noi hou aʻe o ka radiation terahertz i ka wā e hiki mai ana.
