Hele hoʻi ma ka manawa: pehea a me ka wā o ka mua kīwī

Mai ka mua manawa, ua moe kanaka o ka lanakila nānā nui mamao. hōʻike i kēia makemake ka mea, ma ka poʻe hoʻokalakupua manao, a kaao. He nui nā'ōlelo o ka magic aniani keleawe, plateaus, a me nā kilokilo poʻe hoʻokalakupua 'ano o ke kiʻi EYI. Akā, e hana i kēia moe i ka ike maopopo i hiki ole ai lōʻihi aku nei - pono i ka hoʻomaka o ka 20th kenekulia, a me ka wā o ka TV mua - nana aku la e like me ka hana mana ia. Hoikehonua, TV ua ua ike i kekahi mea pakiko-maopopo, aʻaʻohe kekahi manao o keia hana mea hou i hana muaʻole hoʻololi i ke ao nei.

TV: Pehea mea a pau, hoomaka ae la

Lawe mai i ka muaʻimi naʻauao a me ka mea hiki noiʻi ma luna o ke kumuhana o ke kīwī, i lilo ai i loko o ka hopena o 19th kenekulia. I ka 1880, nä känaka 'epekema - American E. Sawyer a me Farani Moris Leblan, i kaumaha aku ai i ke kumu o loina o ka hana o ke kīwī, akā, kona finalization o ka German lunaʻenehana o Paul Nipkow, ka mea ma hope Palapala Sila Nui i kēia' enehana. Kona walaʻauʻana me nā loina e like penei:

kēlā me kēia kiʻi hehee ai e koke scan a me ka sequentially, laina ma ka laina a me ka wahi ponoi ma ke kino pū i hiki. Ka mea, Nipkow iwi kuamoʻo inoa, nana aku la e like me ka kaʻapuni pā hōkū me ke anawaena o 50 knm, a i Ua waiho puka. Image kaʻimiʻana hana 'ia e ka malamalama nana i ulana, a me ka mea mahope EYI o ka neaiaea hula i loko o ka lēkio leo. Ke kīwī mua i hoʻolako pono ia no hoi me ka kaʻapuni pā hōkū me ka lua, a i aia ma ke kua o ka Neon ipukukui, akā, i lawe aku i ke kiʻi kaʻina mai loko aʻe mea. Me keia poe noonoo ole'ōnaehana kiʻi iʻana ma luna o ka pale. Ka mea, ua ka mua TV i loko o ke ao nei, ma muli ma ka manao e moe ana mechanics, nolaila, i ka EYI o ke kiʻi e like ai ua hiki ole. Ma keia manao, o ka me mechanical kīwī e puhi ia mau ae la ia i ka kŘpa a pōkole manawa.

I ka ka mea mua kīwī cathode Ray-ma muli

I ka 1888, i ke aloha a hiki i ka German physicist Genrihu Gertsu, ke ao nei aʻo o ka photoelectric hopena. Nä känaka 'epekema ike ia ka malamalama e loli ai i ka uila, akā, hiki oleʻokoʻa ma wehewehe, a hōʻike i ke' ano o ka kŰia. A wale nō i loko o 1905 ka mea, ua hiki no e Albertu Eynshteynu. I ka 1879, English nä känaka 'epekema Uilyam Kruks hana cathode-Ray şarkı, a wehe ae la i ka mea - ka wā ka mea, e kokoke ana i ko cathode na kukuna o ka phosphors glow. Pela i hoomaka ai i ke au o ka cathode Ray kīwī e puhi ia, a e ho'ōla palahalaha ae ma ka honua. I ka 1936, ka wā o ka mua kīwī i loko o ka uila no, i ka American noiʻi keʻena hoʻokolohua poai puni RCA Lūkini nä känaka 'epekema Zworykin, no laila ka mea, ua manaoia i ka mea hoʻoheheʻe kālā o kēia kīwī. I ka 1939, RCA i hōʻike ai i ka mua kīwī nakeke no ka nuipa a? Iecaianoaaiiie,ʻikeʻia me RCS TT-5. I ka ke kīwī mua, oia ua he nui, a kaumaha lāʻau pahu, i hoʻolako pono me wale i ka 5-'īniha pale. Kekahi manawa malostrochnye (me mechanical) TV'ōnaehana coexisted me ka lolouila, akā, ma ka pau ana o na forties o ka 20th kenekulia ka mea, loa auou caiaiai i ka mīkini uila no.
