Kho qhov muag instrument - lub invention uas hloov noob neej

Kho qhov muag ntaus ntawv - ib tug ntaus ntawv uas converts teeb los ntawm lo ntsiab muag, ntawm uas nws yog tsim los. Niaj hnub nimno science tau ploj mus kom deb li deb, uas tau yees ua ib tug lossis loj tus naj npawb ntawm kho qhov muag pab kiag li lawm, lub npe nrov tshaj ntawm lawv - nws yog tsom-iav, tshuab kuaj kab mob, lub koob yees duab, tsom iav raj. Qhov no tsis yog ib qho exhaustive daim ntawv teev cov chaw ntawm cov ntaub ntawv ntawm cov lo ntsiab muag. Zaum tau tsim ib tug optical ntsuas uas yog tau ua hauj lwm nrog ib tug riam phais neeg, ua tsaug diascopy peb yuav npaj cov duab ntawm qhov screen, thiab cov periscope yog invented rau lub tswvyim ntawm tus Cross.

Ntsiab lus - lub ntsiab uas daim ntawv thov ntawm cov lo ntsiab muag

Tab sis, tej zaum, feem ntau nrov siv lub zog ntawm cov lens - yog siv cov tsom iav. Kho qhov muag tsom iav tseeb tsis pom kev, nce nws sharpness. Yog li ntawd ua ntej koj yuav tau ib khub ntawm lo ntsiab muag nyob rau hauv tus ncej, nws yog tsim nyog los tham ib tug kws kho mob rau kev pab tswv yim rau dab tsi koj xav tau diopters. Txawm hais tias koj muaj ib tug computer tshawb fawb thiab nws tau koj muaj ib tug ntxhib lub tswv yim dab tsi ib tug optical ntsuas koj xav tau, tsis yuav lawv tsis muaj kev noj kev haus koj ophthalmologist. Tom qab tag nrho, tus kws kho mob tej zaum yuav pom zoo kom tsom iav nrog rau lwm cov chav nyob ntawm kev ntsuas ntawm tus kho qhov muag lub hwj huam ntawm lub lens, mus tsim kho lub ua hauj lwm ntawm koj ob lub qhov muag. Tsis tas li ntawd tsis pom zoo kom tau cov ntsiab lus nyob rau hauv random qhov chaw - nyob rau hauv cov ciaj uas muag los yog txoj kev chaw. Yog hais tias koj coj tsom iav nrog lub "tsis yog" lens, lub qhov muag pib cov txheej txheem ntawm adaptation thaum lub cev compensates rau lub distortion ntawm tsom iav eyestrain, mob taub hau, thiab ntxiv deterioration ntawm lub zeem muag.

kev tiv thaiv tsom iav

Tshwj xeeb cov cuab yeej, uas yog tsim los txo cov retina los ntawm qhov tsis zoo lwm los, xws li tsom iav los rau lub computer ua hauj lwm los yog kev tsav tsheb. Tab sis nws yog tsawg kho qhov muag pab kiag li lawm vim hais tias ntawm lawv cov tsom iav muaj ib tug tshwj xeeb txheej uas converts cov duab. Tej zaum cov neeg uas muaj qhov muag pom tsis zoo yuav txiav txim kom koj tsom iav nrog kho qhov muag lo ntsiab muag - xws li yuav tsis tau tsuas yog tsis pom kev, tab sis kuj saib xyuas ntawm lawv cov kev tiv thaiv.

Kho qhov muag newest invention

Science tau leaped rau pem hauv ntej, thiab nyob rau hauv 2010 lub American zaum tau tsim ib tug txhais tau tias rau tshwj kom txhob dig muag nyob rau hauv cov neeg laus - ib tug optical ntaus ntawv uas qub ncaj qha mus rau hauv lub retina. Qhov no me me telescope compensates lub chaw ua hauj lwm puas ob lub qhov muag, thiab ib tug noj qab nyob zoo feem ntawm lub qhov muag tseem mus yuav tau lub luag hauj lwm rau peripheral tsis pom kev. Fornix tau txais cov ntaub ntawv nyob rau hauv ib daim duab - thiab ib tug pom tag nrho cov duab.

Tus invention yog ib tug optical tshuab kuaj kab mob

Rov qab nyob rau hauv thaum ntxov 17th caug xyoo, Galileo yees ib tug yooj yim kho qhov muag ntaus ntawv - ib tug magnifying khob, los ntawm kev uas nws twb tau mus soj ntsuam cov kev ua ntawm microorganisms. Txij thaum ntawd los, ntawm chav kawm, tus kho qhov muag tshuab tau undergone ib tug loj transformation, thiab niaj hnub no nws twb muaj ob tug astigmatic lo ntsiab muag, uas tsis distort cov duab nrog muaj zog refraction ntawm lub teeb, thiab muab ib lub hom phiaj hauv daim duab. Ib tug niaj hnub tshuab kuaj kab mob kev cob cog rua lub computer siv ib tug USB-connector, ua rau nws yuav luag tsis zoo li ib tug invention cov ntse heev Italian, tab sis muaj tib lub hauv paus ntsiab lus ntawm cov lag luam yeej.

Kho qhov muag seev tau invented nyob rau hauv thiaj li yuav pab txhawb lub neej txhua hnub ntawm neeg zoo tib yam, los pab lawv pom dab tsi yog tsis ib txwm tau mus saib tus tib neeg lub qhov muag.
