ʻO nā noi ʻokiʻoki i nā optics i alakaʻi ʻia e nā modulators optical

ʻO ke kumukānāwai ohoʻololi ʻikeʻaʻole paʻakikī. Loaʻa ia i ka modulation o ka amplitude, phase, polarization, refractive index, absorption rate a me nā hiʻohiʻona ʻē aʻe o ka mālamalama ma o ka hoʻoulu ʻana o waho, e hoʻomalu pono i ka hōʻailona optical, e like me ka hiki ʻana i nā kiʻi kiʻi ke lawe a hoʻouna i ka ʻike. Nā ʻāpana kumu o kahi maʻamauelectro-optic modulatore hoʻokomo i ʻekolu ʻāpana: nā kristal electro-optic, electrodes, a me nā mea optical. I ka wā o ka hoʻololi ʻana o ka māmā, hoʻololi ka mea i loko o ka modulator optical i kāna helu refractive, absorption rate a me nā waiwai ʻē aʻe ma lalo o ka mana o nā hoʻoulu ʻana o waho (e like me ke kahua uila, nā kani kani, nā hoʻololi wela a i ʻole nā ​​mana mechanical), a laila e hoʻopili ai i ke ʻano o nā kiʻi i ko lākou hele ʻana i ka mea, e like me ke kāohi ʻana i nā hiʻohiʻona hoʻolaha o ka māmā (amplitude, phase, polarization). ʻO ke aniani electro-optical ke kumu o kamea hoʻololi ʻōpika, kuleana no ka pane ʻana i nā hoʻololi o ke kahua uila a me ka hoʻololi ʻana i kāna ʻōlelo kuhikuhi refractive. Hoʻohana ʻia nā electrodes no ka hoʻopili ʻana i nā māla uila, aʻo nā ʻāpana optical e like me nā polarizers a me nā waveplates e hoʻohana ʻia e alakaʻi a nānā i nā kiʻi e hele ana ma ka aniani.

Nā noi Frontier ma Optik

1.Holographic projection a me ka ʻenehana hōʻike

I loko o ka holographic projection, hiki i ka hoʻohana ʻana i nā modulators optical spatial e hoʻololi maikaʻi i ka hanana ʻana o nā nalu māmā e hiki ai i nā nalu māmā ke keʻakeʻa a ʻokoʻa i kahi ala kikoʻī, e hana ana i kahi māhele māmā paʻakikī. No ka laʻana, hiki i ka SLM e pili ana i ke aniani wai a i ʻole DMD ke hoʻololi i ka pane optical o kēlā me kēia pika, hoʻololi i ka ʻike kiʻi a i ʻole ka hiʻohiʻona i ka manawa maoli, e ʻae ana i nā mea nānā ke nānā i ka hopena ʻekolu-dimensional o ke kiʻi mai nā kihi like ʻole.

2.Opticalʻikepili waihona kahua

Hoʻohana ka ʻenehana hoʻopaʻa ʻikepili Optical i nā hiʻohiʻona kiʻekiʻe a me ka ikaika kiʻekiʻe o ka māmā e hoʻopaʻa a hoʻololi i ka ʻike ma o ka hoʻololi ʻana i ka māmā. Ke hilinaʻi nei kēia ʻenehana i ka mana pololei o nā nalu māmā, me ka hoʻoponopono ʻana i ka amplitude, phase a me ka polarization state, e mālama i ka ʻikepili ma ka media e like me nā disc optical a i ʻole nā ​​mea mālama holographic. ʻO nā modulators Optical, ʻoi aku ka nui o nā modulators optical spatial, he hana koʻikoʻi i ka ʻae ʻana i ka mana optical kikoʻī loa ma luna o ka mālama ʻana a me ka heluhelu ʻana.

Ma ke kahua ʻike, ua like nā kiʻi kiʻi me nā mea hula nani, e hula maikaʻi ana i ka "mele" o nā mea e like me nā kristal, nā kristal wai a me nā fiber optical. Hiki iā lākou ke hoʻololi nani i ke ala, ka wikiwiki, a me ka hoʻokomo koke ʻana i nā "ʻaʻahu kala" ʻokoʻa, e hoʻololi i kā lākou neʻe ʻana a me nā mele, a hōʻike i kahi hana kupaianaha ma hope o kekahi. ʻO kēia mana pololei o nā kiʻi kiʻi ke kī kupua i ka ʻoki ʻana o ka ʻenehana optical e hiki mai ana, e hoʻopiha ana i ka honua optical i nā mea hiki ʻole.
