Yakakura-saizi Machining Kugona

Malenzi akakura-saizi yemaziso (kazhinji anoreva zvinhu zvemaziso ane madhayamita kubva pamakumi emasendimita kusvika kumamita akati wandei) anoita basa rakakosha muhunyanzvi hwemazuva ano hwekuona, nemashandisirwo anotenderera minda yakawanda sekutarisa nyeredzi, laser fizikisi, kugadzira maindasitiri, uye michina yekurapa. Izvi zvinotevera zvinotsanangura mamiriro ekushandisa, basa, uye zviitiko zvakajairika:

1,Kunatsiridza Chiedza Kuunganidza Kugona

Nheyo: Saizi yakakura yelenzi inofanana neyakakura chiedza-aperture (inoshanda nzvimbo), ichigonesa kuunganidzwa kwesimba rakawanda rechiedza.

Mamiriro ekushandisa:

Observation of Astronomical Observation: Semuyenzaniso, 18 hombe-sized beryllium lenses of the James Webb Telescope inotora faint starlight kubva 13 bhiriyoni light-year kure nekuwedzera nzvimbo yekuunganidza chiedza.

2, Yakakwidziridzwa Optical Resolution uye Imaging Precision

Musimboti: Zvinoenderana neiyo Rayleigh criterion, iyo yakakura iyo lens aperture, iyo yakakwirira diffraction-limited resolution (formula: θ≈1.22λ/D, apo D ndiyo dhayamita yelenzi).

Mamiriro ekushandisa:

Remote Sensing Satellites: Hombe-saizi chinangwa lenzi (semuenzaniso, 2.4-mita-mita lens yeUS Keyhole satellite) anogona kugadzirisa pasi zvinotarisirwa pachiyero 0.1-mita.

3, Modulation yeChiedza Phase, Amplitude, uye Polarization

Technical realization: Wavefront maitiro echiedza anoshandurwa kuburikidza nepamusoro chimiro dhizaini (semuenzaniso, parabolic, aspheric nzvimbo) kana maitiro ekunamira pane lens.

Zvakajairika Zvishandiso:

Gravitational Wave Detectors (LIGO): Yakakura-yakakura fused silica lenses inochengetedza kugadzikana kwechikamu chekupindira kwelaser kuburikidza nepamusoro-chaiyo yepamusoro maumbirwo (zvikanganiso <1 nanometer).

Polarization Optical Systems: Yakakura-saizi polarizers kana wave mahwendefa anoshandiswa mune laser kugadzirisa michina kudzora polarization mamiriro e lasers uye kukwidziridza kugadzirisa zvinhu.
