Yuav ua li cas yuav ua rau ib tug laser nrog koj ob txhais tes tsis muaj ntxiv nqi

Laser - ib tug tshaj plaws pab tau thiab nthuav. Tag nrho tej zaum ua si raws li ib tug me nyuam pheej yig Suav pointers. Txawm li cas los, thaum lub sij hawm nws yuav paub tseeb hais tias qhov no yog tus me nyuam ua si. Thiab ces nws pib siav lub tswv yim ntawm yuav ua li cas yuav ua rau ib tug loj, muaj hwj chim loj laser uas yuav txiav steel, zoo li nyob rau hauv qhov tsos. Steel, alas, nws yog heev yooj yim mus txiav, nws ua tau tsuas yog haib muaj cov cuab yeej. Yog li ntawd, cia peb sim pib kawm ua li cas yuav ua rau ib tug laser nrog nws tus kheej txhais tes, yog li ntawd rau txiav ib yam dab tsi tsawg zog, xws li yas.

cov txheej txheem

Yog hais tias koj nug cov engineer txog yuav ua li cas yuav ua rau ib tug laser nrog nws ob txhais tes, nws tswv yim mus coj ib tug haib teeb thiab tsom lub teeb rau hauv ib lub beam. Txawm li cas los, qhov no yog tsis tiag tiag ib tug laser. Lub ntsiab sib txawv ntawm cov laser lub teeb los ntawm lub teeb xais beam coherence. Lub laser yog tiag tiag, nws yog tsim nyog los noj, piv txwv li, lub tib lub npe ntawm tus kws ntaus ntawv (yuav tsum tau!) CD los yog DVD-tsav. Laser muaj hwj chim loj txaus, ntau dua qhov lub ceev, lub zog nws yog.

cov khoom

Nyob rau hauv tas li ntawd mus rau lub tsav, peb yuav tsum tau:

- ob capacitors: ncov qaumteb qabteb 2200 uf thiab 100 PF;

- 3.6V fais fab mov, 150-170 MA (haum tooj ntawm thaum uas tig mus roj teeb ntawm xov tooj);

- resistor 2 ... 5 ohms;

- vaj tsev kub tog (nrog rau cov laser yog heev rhuab);

- soldering hlau;

- ntswj ntsia hlau, pliers, hluav taws xob kab xev.

extraction

Cia peb tsav tsheb. Muaj yuav qhia ob laser IR-laser nyeem ntaub ntawv (nws yuav lens) thiab tus kho qhov muag cov ntaubntawv povthawj siv, nws yog raws nraim li cas peb xav tau. Nyob rau hauv tas li ntawd mus rau lub laser, tsis txhob hnov qab tau ntau thiab lens. Qhov no yuav tsum tau ua tib zoo thiaj li tsis mus ua puas lub yuav tsum tau qhov chaw. Ceeb toom! Thaum ua hauj lwm nrog ib tug laser tsis txhob muaj zoo li qub, nws yuav txhob cuam tshuam txog nws cov qauv thiab tig mus rau hauv ib tug dog dig diode. Nyob rau hauv tas li ntawd, nws nyob rau hauv tsis muaj txoj kev yuav kev cob cog rua rau lub roj teeb ncaj qha.

tswvyim

Rau laser lag luam yuav tsum tau ib tug hluav taws xob Circuit Court hais tias yuav ua tau tej solder. Nws muaj ob capacitors kev cob cog rua nyob rau hauv thaum uas tig mus rau txhua lwm yam thiab mus rau lub laser nws tus kheej (zoo polarity tso zis capacitor yog soldered mus rau lub tswv yim ntawm cov laser thiab qhov zoo ncej SP). Tsis tas li ntawd, rau qhov zoo tso zis SP soldered resistor. Lub schema yuav muaj. Nyob rau hauv no cov tswvyim siab tsis tau, tab sis nws yog straightforward. Yog hais tias koj xav mus ua ib yam dab tsi ntau dheev, nws yog ua tau rau solder ib tug ntau tswvyim raws li LM317 los yog LM2621 nti.

hloov

Txawm li cas los, Yog hais tias koj cia li tig rau lub laser, nws yuav tsis tsim kom muaj qhov beam. Nws yuav ci li ib lub teeb khoo, tsuas liab. Yuav ua li cas yuav ua rau ib tug laser nrog koj ob txhais tes los ntawm no ntaus ntawv? Cia peb nco ntsoov tias lwm qhov chaw yog muab rho tawm los ntawm tus tsav lens. Nws yuav siv tau los ua kom pom tseeb rau hauv lub teeb rau hauv ib lub beam txoj kab uas hla ntawm lub 1 hli los yog rau ib tug taw tes ib txhia nyob deb deb. Yog hais tias koj xav tau ib tug pointer, nws yog zoo dua kom haum lub beam, thiab hlawv ntau yooj yim taw tes. Tag nrho ntaus ntawv yog muab tso rau hauv ib lub tsev nyob muaj ib tug khawm thiab cua. Tus ntaus ntawv yog npaj txhij.

kev nyab xeeb

Ceeb toom! Lub laser yog haib heev! Xws li ib tug tshaj plaws yuav hlawv lub retina yooj yim rau cov neeg uas yuav mus saib rau nws. Nyob rau hauv txhua rooj plaub, ua ntej ib tug laser ntawm DVD, obzavedites goggles. Thiab yeej tsis taw tes nws mus rau ib tug neeg lub ntsej muag!

Tam sim no hais tias peb paub yuav ua li cas yuav ua rau ib tug laser nrog koj ob txhais tes, koj muaj peev xwm pib ignition ntawm qhov yuam kev, tej pob khoom thiab lwm yam xwm txheej.
