Lub cev muaj zog Galvanometer: Lub cev muaj zog servo lossis lub cev muaj zog galvanometer nrog lub sijhawm teb ntawm <1ms.

1.3 Dynamic Focusing Module (F-Theta Lens lossis Galvanometer + Flat-Field Lens)

F-Theta Lens

Kev Ua Haujlwm: Hloov lub kaum sab xis ntawm lub galvanometer mus rau hauv qhov kev hloov pauv linear ntawm lub dav hlau kom tswj tau qhov sib xws ntawm qhov tsom mus rau.

Cov qauv tseem ceeb:

2. Txoj Cai Ua Haujlwm

Txoj kev teeb tsa: Laser → Collimator → X galvanometer → Y galvanometer → F-Theta lens → Qhov chaw ua haujlwm.

Kev tsom mus rau qhov tseeb:

Thaum lub kaum sab xis ntawm galvanometer yog θ, qhov chaw tsom mus rau (x, y) raug hloov los ntawm F-Theta lens li:

3. Cov Qauv Tseem Ceeb thiab Cov Qauv

3.1 Kev Xam Qhov Loj ntawm Qhov Chaw

Qhov chaw tsom mus rau txoj kab uas hla d (kev txwv diffraction):

3.2 Kev Ntsuas Ntau Yam thiab Lub kaum sab xis Galvanometer

Qhov siab tshaj plaws ntawm kev luam theej duab L:

3.3 Kev Ceev thiab Kev Ua Kom Vuam Sai

Qhov ceev v

3.4 Qhov tob ntawm kev tsom mus rau (DOF)

3.5 Lub zog ceev thiab lub zog nkag

Lub zog ceev kuv:

Lub zog ceev E (pulse vuam):

4. Kev Txawv Txawv thiab Kev Tsim Kho Kom Zoo

4.1 Kev Kho Qhov Tsis Zoo ntawm Lub Lens F-Theta

Kev Distortion: Nws yuav tsum tau ua kom txaus siab rau r∝θ, thiab qhov kev cuam tshuam nonlinear yuav tsum <0.1%.

Qhov nkhaus ntawm thaj teb: Tsim ib thaj teb tiaj tiaj los ntawm ntau pawg lens.

4.2 Kev Ua Yuam Kev Sib Tshuam Galvanometer

Qhov kev ncua sij hawm X/Y galvanometer yuav tsum <1μs kom tsis txhob muaj cov pob elliptical.

5. Piv txwv ntawm Cov Txheej Txheem Tsim Qauv

Cov kev cai nkag: Ntau yam luam theej L, qhov loj ntawm qhov chaw d, qhov ceev vuam v. Xaiv F-Theta lens: Txheeb xyuas fθ raws li L=2fθtan(θmax).

Xam cov kev ntsuas galvanometer: Angular velocity ω=v/fθ, thiab xyuas kom meej tias galvanometer ua haujlwm tau zoo.

Txheeb xyuas qhov zoo ntawm qhov chaw: Txhim kho qhov tsis zoo ntawm pawg lens los ntawm Zemax/OpticStudio.

6. Kev ceev faj

Kev tswj cua sov: Galvanometers thiab lenses xav tau dej txias hauv qab lub zog siab (xws li >1kW).

Kev tiv thaiv kev sib tsoo: Galvanometers xav tau kev nres tsheb thaum muaj xwm ceev kom tsis txhob muaj kev sib tsoo tshuab.

Kev Kho Kom Zoo: Kho kom zoo tsis tu ncua txoj kev kho qhov muag coaxiality (kev sib txawv <0.05mm).
