Whakaahua Matua o te LIT-6 Precision Interferometer

Inenga Waenga Tika LIT-6

Whakaahuatanga Poto:

Ka whakakotahihia e tēnei taputapu te ine whakawhiti Michelson, te ine whakawhiti Fabry-Perot, me te ine whakawhiti Twyman-Green i roto i te tūāpapa kotahi. Mā te hoahoa auaha me te hanganga whakauru o te taputapu ka taea te whakaiti i te wā whakatikatika whakamātautau me te whakapai ake i te whai huatanga o te whakamātautau. I taua wā anō, ka mau ngā wāhanga hanganga katoa ki runga i te tūāpapa taumaha iti, ka taea te ārai i te pānga o te wiri ki te whakamātautau. Ka taea te huri ngāwari i te whakararuraru a Michelson, Fabry Perot, prism me te arotahi i waenga i ngā momo e whā, he ngāwari te whakahaere, he tika te hua, he nui te ihirangi o te whakamātautau, he taputapu pai mō te whakahaere i te whakamātautau whakararuraru whakakotahi.
