Umthombo: iSayensi kunye neTekhnoloji Daily

Ngophuhliso olukhawulezayo lwesayensi kunye nobuchwepheshe bale mihla, ifilimu ye-laser, njengento ekhulayo, iye yangena ngokuthe ngcembe kumbono wabantu. Ayibonisi kuphela usetyenziso olubanzi ekupakishweni, iimveliso ze-elektroniki, ishishini leemoto kunye neminye imimandla, kodwa ivuselela iindlela ezintsha zokuyila kwiinkalo zobugcisa kunye noyilo. Eli nqaku liza kuphonononga imbali yophuhliso lwefilimu ye-laser kwaye ixoxe ngendaleko yayo yetekhnoloji kunye nethemba elizayo.

1. Imvelaphi kunye nophuhliso lwangethuba

Imvelaphi yefilim yelaser inokulandelwa emva phaya kwiminyaka yoo-1960, xa oosonzululwazi babefunda itekhnoloji yelaser baza bafumanisa ukuba imiqadi yelaser inokuvelisa iziphumo ezikhethekileyo zamehlo ngokusebenzisa imathiriyeli ethile. Ngeminyaka yee-1970, njengoko iteknoloji yelaser ikhula, abaphandi baqala ukuzama ukusebenzisa ezi zakhiwo zamehlo kuphuhliso lwezixhobo zefilimu ezibhityileyo.

2. Ukuphumelela kwezobuchwepheshe kunye norhwebo

Ngeminyaka yee-1980, impumelelo enkulu yenziwa kwitekhnoloji yokuvelisa ifilim yelaser. Ngokusebenzisa ubuchule obunje nge-vacuum evaporation kunye ne-sputtering, abavelisi bayakwazi ukuvelisa iifilimu ze-laser ezinokubonakala okuphezulu kunye nemiphumo enemibala. Ngeli xesha, iifilimu ze-laser zaqala ukusetyenziswa kwishishini lokupakisha, ngakumbi kwizinto zokuthambisa kunye nokupakishwa kokutya, ukutsala ingqalelo yabathengi.

Kwiminyaka ye-1990, ngophuhliso lwesayensi yezinto eziphathekayo, ukusebenza kweefilimu ze-laser kwaphuculwa ngakumbi. Ukuvela kweepolymers ezintsha kwenza iifilimu ze-laser zingabi neempawu ezibalaseleyo zamehlo kuphela, kodwa zinokomelela okungcono kwaye zinobuhlobo ngakumbi nokusingqongileyo. Ngeli xesha, umda wokusetyenziswa kweefilimu ze-laser uqhubekile ukwandisa, ngokuthe ngcembe ungene kwiindawo ezininzi ezifana neemveliso ze-elektroniki kunye nokuhombisa imoto.

3. Izicelo zangoku kunye nezinto ezintsha

Ukungena kwinkulungwane yama-21, ukwenziwa kwezinto ezintsha kunye nokwenza ngokwezifiso itekhnoloji yefilimu ye-laser ibe yindlela entsha yophuhliso. Iinkampani ezininzi sele ziqalisile ukuphuhlisa iifilimu ze-laser ezineziphumo ezibonakalayo eziguquguqukayo, kwaye abathengi banokukhetha iziphumo ezahlukeneyo zamehlo ngokwezinto abazithandayo. Ukongeza, ukusetyenziswa kwezinto ezihambelana nokusingqongileyo kuye kwaba ngulwalathiso olubalulekileyo kuphuhliso lweshishini. Iinkampani ezininzi zizinikele ekuphuhliseni iifilimu zelaser ezonakalayo ukuze zijongane nemiba ekhulayo yokusingqongileyo.

Kwiinkalo zobugcisa kunye nokuyila, iimpembelelo ezibonakalayo ezibonakalayo zefilimu ye-laser ziye zatsala ingqalelo yabaqulunqi abaninzi. Imisebenzi emininzi yobugcisa kunye neemveliso zefashoni sele iqalile ukubandakanya izinto zefilimu ye-laser, ukudala amava abonakalayo amangalisayo.

4. Amathemba ekamva

Ngophuhliso oluqhubekayo lwenzululwazi nobuchwepheshe, ifilimu yelaser iya kuba nenkqubela phambili kwimiba eyahlukeneyo. Kulindeleke ukuba kule minyaka imbalwa izayo, iifilimu ze-laser ziya kudlala indima enkulu kwiinkalo ezifana nokupakishwa okukrelekrele, izixhobo ezinxitywayo, kunye nokuhonjiswa kwezakhiwo. Ngexesha elifanayo, njengoko abathengi benikela ingqalelo ekukhuselweni kwendalo kunye nophuhliso oluzinzileyo, ukuphuhliswa kwezixhobo zefilimu ye-laser ehambelana nokusingqongileyo kuya kuba yinto ebalulekileyo kwishishini.

Ngamafutshane, imbali yophuhliso lwefilimu ye-laser ayiyona nje inkcazo yenkqubela phambili yezobuchwepheshe, kodwa kunye nokubonakaliswa kweenguqu kwimfuno yemarike. Ngokuziphendukela okuqhubekayo kobuchwepheshe, ifilimu yelaser iya kubonisa umtsalane wayo okhethekileyo kwiindawo ezininzi kwaye ibe yinxalenye ebalulekileyo yobomi banamhlanje.
