Porogaramu imirima ya acousto-optique modulator (AOM Modulator)

Ihame rya Acousto-optic modulator:

An moderi ya acousto-optique(AOM Modulator) mubusanzwe igizwe na kristu ya acousto-optique, transducers, ibikoresho byo kwinjiza hamwe nabashoferi. Ibimenyetso byahinduwe biva mubushoferi bikora kuri transducer muburyo bwikimenyetso cyamashanyarazi hanyuma bigahinduka umuyaga wa ultrasonic uhinduka muburyo bwikimenyetso cyamashanyarazi. Iyo ultrasonic wave inyuze muri acousto-optique, itera kwikanyiza kwaho no kurambura hagati, bikabyara imbaraga za elastique. Iyi mitekerereze ihinduka mugihe hamwe n'umwanya, bigatuma uburyo bwo kwerekana ibintu bigenda bisimburana, bisa na feri yo gusya. Iyo urumuri runyuze muri ubu buryo bubangamiwe n’umuraba wa ultrasonic, ibintu bitandukana. Iyi phenomenon yitwa ingaruka ya acousto-optique. Ingaruka yijwi numucyo, itwara optique irahindurwa kandi ihinduka umurongo uhindagurika "utwara" amakuru.

Porogaramu nyamukuru ya moderi ya acousto-optique:

Ijwi n'umucyo Q Hindura (AOQS)

Acoutooptic Q-switch switch (AOQS) ikorera mumyanya ya laser kandi ihindurwa cyane

Q agaciro mumyanya ikoreshwa mugutanga lazeri hamwe na pulses ngufi nimbaraga zo hejuru. AOQS isanzwe ikoreshwa muguhindura igihombo cya 0-itondekanya. Iyo radiyo yumurongo wa radiyo ya AOQS ifunguye, urumuri 0-rwateganijwe, kubera gutandukana, rurinda lazeri mu cyuho kunyeganyega, kongera igihombo no guhagarika lazeri. Iyo umushoferi wa radiyo yumurongo azimye mugihe gito, imbaraga za optique zegeranijwe mumyanya ya laser zisohoka muburyo bwa pulses, bityo bikabyara laser. Iyi nzira irashobora gusubirwamo ku gipimo kirenga 100KHz. Iyo AOQS ikorera muri leta ya Bragg, habaho urumuri rumwe gusa. in

Hariho ibiti byinshi byo gutandukanya iyo ukora muri leta ya Raman - Niss.

2. Moderi ya Acousto-optique / Hindura (Moderi ya AOM)

Abayobora moderi ya Acousto-optique (AOM) muri rusange bikoreshwa hanze ya laser cavit kugirango bahindure ubukana bwibyabaye laser (amplitude modulation AM). Ibi birashobora kuba byoroshye ON / OFF modulasiyo yo guhinduranya byihuse cyangwa guhinduka kurwego rwo guhinduka kugirango ugere kubikorwa byimbaraga. Uburyo bwo guhindura ibintu bugenwa nubwoko bwumushoferi wa RF kandi burashobora kuba digitale (kuri / kuzimya) cyangwa kugereranya (sine, kwaduka kare, umurongo, utabishaka…). Muri rusange, disiki ya RF ya AOM ifata inshuro ihamye. Urufunguzo rwibanze rwaUmuyobozi wa AOMnigihe cyo kuzamuka / kugwa, bisobanura kugerwaho "umuvuduko" cyangwa amplitude modulation bandwidth ya modulation. Igihe cyo kuzamuka / kugwa kiringaniye na diameter ya beam muri modulator. Kubwibyo, kugirango ubone igihe cyo kuzamuka byihuse, diameter yibyabaye laser igomba kugenzurwa. AOM irashobora gukoreshwa nka shitingi (gusiganwa ku magare no kuzimya kuri franse yagenwe) kandi nanone nka attenuator ihinduka (kugenzura imbaraga zumucyo woherejwe). Guhindura Laser bigerwaho mugucunga radiyo inshuro nyinshi kugirango itere amajwi muri acousto-optique.

3. Acousto-optic deflector (AODF)

Indwara ya acoutooptic (AODF) irashobora kugera kumurongo ushimishije muguhindura radiyo yumurongo wa radiyo. Ikibanza cyo gusikana gishobora kuba umwanya utunguranye, umurongo uhoraho wo gusikana no gutandukanya ingingo ikurikiranye. Ukurikije kristu, uburebure bwumurambararo nubunini bwa beam, igihe cyo gusubiza 0,05 kugeza 15 microseconds hamwe no kugenzura neza imyanya ya nRad irashobora kugerwaho.

4. Shouter ya Acousto-optique (AOFS)

Nyuma yo kunyura mubikoresho byose bya acousto-optique, itandukanyirizo risohoka ryibiti bya laser bizatanga impinduka zinshyi. Acousto-optic frequency shift (AOFS) nigikoresho cyoroheje cyagenewe kugerwaho kugirango uhindurwe. Ukurikije ibyatoranijwe byatoranijwe bitandukanye, AOFS izahindura inshuro hejuru cyangwa munsi yumurongo wikimenyetso cya radio ikoreshwa, kandi ibikoresho bibiri cyangwa byinshi birashobora gutondekwa kugirango ugere kumafaranga cyangwa itandukaniro ryinshuro. Ibicuruzwa bya AOFS bifata imiterere yihariye ya acoustic absorber angles, ishobora kugabanya amajwi yerekana kandi ikazamura imikorere ya AOFS.

5. Acousto-optique Guhindura Akayunguruzo (AOTF)

Acousto-optic tunable filter (AOTF) ni leta-ikomeye, yandikirwa kuri elegitoronike kandi igerwaho kubushake bwa optique passband filter. Irashobora gukoreshwa muburyo bwihuse kandi bwihuse guhitamo uburebure bwihariye bwumurongo mugari cyangwa imirongo myinshi. Gutandukana bibaho mugihe ibintu byihariye bihuye byujujwe hagati yibiti bya acoustic. Kubwibyo, birashoboka kugenzura uburyo bwa elegitoronike ibipimo byungurura (nkuburebure bwumurambararo, ubujyakuzimu bwimbitse, ndetse numuyoboro mugari), bityo bigatanga byihuse (mubisanzwe microseconds), imbaraga, nuburyo butunguranye bwo gushungura optique.
