Sumaisisitimu yemazisoyekubvisa nekugamuchira ne laser
Sisitimu ye laser emission and reception optical ine zvikamu zviviri zvikuru: emission optical module uye reception optical module. Nzvimbo dzayo dzinonyanya kushandiswa dzinosanganisira laser processing systems, fluorescence detection systems uye Raman spectroscopy detection systems.
1. Module ye optical emission ndiyo inonyanya kuita kuti laser beam ikwanise kuunganidzwa, kukudziridzwa kana kuumbwa, kuitira kuti ikwanise kuburitswa ne specific parameters dzakadai se beam quality, divergence Angle uye energy distribution. Module ye optical inogashira inoshandiswa kuunganidza laser signal inoonekwa kubva ku target, kuita focus, filtering nezvimwe zvinoshandiswa pairi, kuitira kuti zviite kuti ionekwe uye igadziriswe zviri nyore.
Iyokubuda nelaserSisitimu iyi ine zvinhu zvakakosha zvakaita sechiedza chinobuda nelaser, boka remalenzi anounganidza, chinowedzera beam uye chinhu chinoumba. Sesimba resisitimu yese, maparamita ekushanda kwechiedza chinobuda nelaser, akadai sekugadzikana kwewavelength uye hunhu hwesimba rinobuda, anoona zvakananga mhedzisiro yekushanda kwemaziso kunotevera. Boka remalenzi anounganidza, kuburikidza nekugadzirwa kwakanyatsojeka kwemaziso, rinodzvanya Angle yekusiyana kwelaser beam kusvika padanho diki kwazvo, zvichiita kuti laser irambe iine simba rakawanda panguva yekutumira kure. Chinowedzera beam chinokudza dhayamita yelaser beam zvichienderana nezvinodiwa chaizvo kuti zvisangane nezvinodiwa zvekushandisa mumamiriro akasiyana. Chinhu chinoumba chinogadzirisa chimiro chelaser beam nekushandura kugoverwa kwechikamu kana amplitude yelaser beam, senge kushandura danda reGaussian kuita danda rakatsetseka, kuti risangane nezvinodiwa zvemhando yebeam mumamiriro chaiwo ekushandisa.
2. Iyokugamuchira neraserSisitimu iyi ine zvikamu zvikuru zvakaita seboka remalenzi anogamuchira, mafirita, uye photodetector. Boka remalenzi anogamuchira rine basa rekuunganidza zvinobudirira masaini elaser asina simba anoratidzwa kubva kuchinangwa uye kuaisa pamusoro pe photodetector kuburikidza nekugadzirwa kwakanyatsojeka kwe optical kuti kuwedzere kushanda zvakanaka kwekugamuchira masaini. Mafirita anoshandiswa kusefa ruzha rwekumashure nemamwe masaini echiedza anopindira, zvichiita kuti masaini elaser ema wavelengths chaiwo asvike pa detector, nokudaro zvichivandudza chiyero chesignal-to-noise uye kururama kwekuona kwesisitimu. Sechikamu chekupedzisira chesisitimu yekugamuchira laser, maparamendi ekushanda kwemudziyo wekuona foto, zvakaita sekunzwa uye nguva yekupindura, zvinosarudza zvakananga kugona kwesystem kuona uye kumhanya kwekugadzirisa masaini elaser.
