Molo, Habr. Kweli nqaku ndiza kuthetha ngendalo yam yamva nje, eyenziwe kwiimodyuli ze-laser ezingama-500 ezifanayo nezikhombisi zelaser ezinexabiso eliphantsi. Kukho imifanekiso emininzi ecofayo phantsi kokusikwa.
Ingqalelo! Nditsho ne-laser-low-power emitters phantsi kweemeko ezithile kunokubangela ingozi empilweni okanye konakalise izixhobo zokufota. Musa ukuzama ukuphinda imifuniselo echazwe kweli nqaku.
Phawula. Vula , apho unokubona ngakumbi. Nangona kunjalo, inqaku lichaza inkqubo yokudala ngokubanzi kwaye kukho imifanekiso esemgangathweni engcono (ingakumbi xa ucofa).
Iimodyuli zeLaser
Ndiza kuqala ngenkcazo yeemodyuli ze-laser ngokwazo. Ngoku zithengiswa kwiinguqulelo ezininzi ezahlukeneyo, ezahlukileyo kubude bobude, amandla kunye nokumila kwemitha yemveliso, uyilo lwenkqubo yokukhanya kunye nokunyuka, kunye nomgangatho wokwakha kunye nexabiso.
Ndakhetha iimodyuli ezingabizi kakhulu, ezithengiswa e-China kwiibhetshi zeenqununu ze-100, zibiza malunga ne-ruble ye-1000 ngebhetshi nganye. Ngokwenkcazo yomthengisi, bavelisa i-50 mW kwi-wavelength ye-650 nm. Ndiyathandabuza malunga ne-50 mW, kunokwenzeka ukuba akukho nokuba yi-5 mW. Ndithenge iimodyuli ezininzi ezifanayo eRashiya ngexabiso leeruble ezingama-30 nganye. Kwiivenkile ze-intanethi zifumaneka phantsi kwegama elithi LM6R-dot-5V. Zikhazimla njengezalathisi ezibomvu zelaser ezithengiswa ngeendlela ezahlukeneyo kulo naliphi na ithala le-knick-knack.
Ngokwesakhiwo, le modyuli ibonakala ngathi i-cylinder yensimbi kunye nobubanzi be-6 mm kunye nobude be-14 mm (kubandakanywa nebhodi). I-case material inokwenzeka ukuba yintsimbi, njengoko ineempawu ezintle zamagnetic. Indlu iqhagamshelwe kunxibelelwano oluhle.
Ngaphakathi kwimeko kukho i-lens yeplastiki kunye ne-laser chip efakwe kwibhodi yesekethe encinci eprintiweyo. Kukho kwakhona i-resistor ebhodini, ixabiso elixhomekeke kwi-voltage yokubonelela echazwe. Ndisebenzise iimodyuli ze-5V kunye ne-91 ohm resistor. Ngegalelo lombane we-5V kwimodyuli, i-voltage kwi-chip laser yi-2.4V, ebangela ukuba kubekho i-28 mA yangoku. Uyilo luvuleleke ngokupheleleyo kwicala lebhodi, ngoko ke naluphi na uthuli okanye ukufuma kunokungena lula ngaphakathi. Ke ngoko, nditywine ngasemva kwimodyuli nganye ngeglue eshushu. Ukongeza, i-chip kunye ne-lens ayihambelani ngokuchanekileyo, ngoko ke imveliso ayinakuhambelana ne-axis yomzimba. Ngexesha lokusebenza, imodyuli iyatshisa ukuya kumaqondo obushushu angama-35-40 Β° C.
inguqulelo yoqobo
Ekuqaleni (oku kwakungonyaka odlulileyo) ndathenga iimodyuli ze-laser ezingama-200 kwaye ndagqiba ekubeni ndiqondise kwindawo enye usebenzisa indlela yejometri ecocekileyo, oko kukuthi, kungekhona ukulungelelanisa imodyuli nganye, kodwa ukufaka i-emitter nganye kwi-cutouts ekhethekileyo. Kule nto ndayalela i-fastenings ekhethekileyo eyenziwe nge-plywood eyi-4 mm.
Iimodyuli ze-laser zixinzelelwe kwi-cutout kwaye zixutywe ngeglue eshushu. Umphumo waba lufakelo oluvelisa umqadi wamanqaku angama-200 e-laser kunye nobubanzi obumalunga ne-100 mm. Nangona umphumo wawukude nokubetha uphawu, abaninzi bachukumiseka ngulo mbono (ndathumela ividiyo kwi-YouTube) kwaye kwagqitywa ukuba kuqhutywe isihloko.
Ndaqhawula inkqubo yeemodyuli zelaser ezingama-200 ndaza ndenza isidanga selaser ngazo. Kwabonakala kunomdla, kodwa akufanelekile, kuba phantsi kobunzima bomzimba yonke imisebe yayiqondiswe phantsi. Kodwa ngeli xesha ndithenge umatshini wenkungu kwaye okokuqala ndabona indlela ezipholile ngayo ezi lasers kwinkungu. Ndigqibe kwelokuba ndiphinde umbono wokuqala, kodwa ndalathisa ngelaser nganye kwindawo enye.
Ukukhanya kweLaser
Kwinguqulelo entsha, ndayalela ezinye iimodyuli ze-laser ezingama-300. Njengokuzila, ndenze iplati yesikwere kunye necala le-440 mm ukusuka kwi-plywood eyi-6 mm ene-matrix yemingxuma ye-25 imigqa kunye ne-20 columns. Umngxuma ububanzi 5 mm. Ethubeni ndayipeyinta ngesiliva. Ukuqhoboshela ipleyiti ndasebenzisa i-stand kwi-monitor ye-LCD endala.
Ndiyikhusele iplate kwi-vice, kwaye kumgama we-1350 mm (ubude betafile yam) ndaxhoma ithagethi yephepha elilinganisa i-30x30 mm, kwiziko apho ndiqondise i-laser beam nganye.
Inkqubo yokuncamathelisa imodyuli yelaser ibe ngolu hlobo lulandelayo. Ndafaka iingcingo zemodyuli emngxunyeni kwaye ndadibanisa iingwenya kunye ne-voltage yokubonelela kubo. Emva koko, ndazalisa umzimba wemodyuli kunye nomngxuma kwiplate ngeglue eshushu. Kwakukho ifeni phantsi kwepleyiti ukukhawulezisa ukupholisa iglu. Ekubeni i-glue iqinisa ngokukhawuleza, ndiyakwazi ukulungelelanisa indawo yemodyuli, ndigxininise kwindawo yechaphaza lelaser kwithagethi. Ngokomyinge indithathe 3.5 imizuzu kwimodyuli yelaser.
Kukulungele ukusebenzisa iglue ye-melt eshushu, njengoko inokufudumeza kwaye imodyuli inokulungiswa. Nangona kunjalo, zimbini izinto ezingalunganga. Okokuqala, ukufudumeza iimodyuli kwakhokelela ekuguqulweni kwesakhiwo semodyuli, ebonakaliswe ekwandiseni i-laser beam. Ezinye iimodyuli zalahleka ngokukhawuleza ukuqaqamba ngenxa yokufudumeza kwaye kwafuneka zitshintshwe. Okwesibini, emva kokupholisa, iglu eshushu-enyibilikayo yaqhubeka ikhubaza iiyure ezininzi kwaye iphambukisa kancinci umqa we-laser kulo naliphi na icala. Into yokugqibela isinyanzele ukuba sitshintshe igama lokuqala leprojekthi "500 laser pointers ngexesha elinye."
Ekubeni umsebenzi wawusenziwa ngamaxesha athile ngokuhlwa nangeempelaveki, kwathatha malunga neenyanga ezintathu ukuncamathelisa zonke iimodyuli ezingama-500 zelaser. Ukuthathela ingqalelo ukuhanjiswa kweemodyuli kunye neepleyiti, kuya kuba ziinyanga ezintandathu.
Ngempembelelo ekhethekileyo, ii-LED eziluhlaza zongezwa kwiimodyuli ze-laser.
Ukunika amandla kuzo zonke iimodyuli akuwona umsebenzi olula, kuba kufuneka udibanise abafowunelwa be-1000 kwaye usasaze ngoku ngokulinganayo. Ndidibanise bonke abafowunelwa abalungileyo abangama-500 kwisekethe enye. Ndahlula abafowunelwa abangalunganga kumaqela ali-10. Ndabela eyam iswitshi kwiqela ngalinye. Kwixesha elizayo, ukwenza amaqela asebenze, ndizakongeza i-10 izitshixo ze-elektroniki ezilawulwa sisilawuli esincinci esinomculo.
Ukunika amandla zonke iimodyuli, ndithenge umthombo wombane oqhubekayo , ovelisa i-voltage ye-5V kunye ne-current ukuya kwi-60A. Incinci ngobukhulu kwaye inebhloko ye-terminal efanelekileyo yokudibanisa umthwalo.
Isiphaluka sokugqibela kunye nazo zonke iimodyuli ze-laser ezivuliwe zinokusetyenziswa malunga ne-14 amperes. Lo mzobo ungezantsi ubonisa indawo yazo zonke iingongoma ze-laser kwithagethi. Njengoko ubona, ndiphantse ndangena "kwindawo enye" ββyokulinganisa i-30x30 mm. Indawo enye ngaphandle kokujoliswe kuko yavela ngenxa yemodyuli enye enemitha esecaleni.
Isixhobo esibangelwayo asibonakali sihle kakhulu, kodwa bonke ubuhle bayo bubonakaliswe ebumnyameni nakwinkungu.
Ndazama ukubamba apho imitha inqumla khona. Ubushushu buvakala, kodwa abunamandla.
Kwaye ndade ndakhomba ikhamera ngokuthe ngqo kwi-emitters (mna ngokwam ndisebenzisa iiglasi zokhuseleko eziluhlaza).
Kwakumnandi ngokwenene ukusebenzisa izipili kunye neelensi.
Kamva ndongeza ukukwazi ukumodareyitha iimodyuli ze-laser kunye nesignali yomsindo kwaye umphumo wawuluhlobo lokufakwa kwe-laser yomculo. Ungayijonga .
Le projekthi yenzelwe ukuzonwabisa kwaye ndanelisekile ziziphumo. Okwangoku, andizibeki imisebenzi efanayo echitha ixesha, kodwa kwixesha elizayo mhlawumbi ndiza kuza nenye into. Ndiyathemba ukuba uyifumene inomdla nawe.
