Laser Spot Stability kha Field Scanning nganpi ah zeitindah tthanchoter khawh a si
1. Laser Spot Stability timi cu zeidah a si?
Laser hmunhma fek tein um khawhnak nih laser ceunak nih a tanglei thil hna hi a kilven khawhnak kha a chim duhmi a si:
-
Aa khatmi hmunhma ngan
-
Aa khatmi thazaang phawtzamhnak
-
A dikmi lungthin peknak dirhmun
-
Hlathlainak hmun dihlak ah a fekmi muisam
A nganmi hmun zohfelnak system ah, a hmete in aa mernak hmanh nih a tanglei ah a chuahpi khawh:
-
Aa tluk lomi hmelchunhnak thuknak
-
A fiang lomi tthen
-
Aa thlengmi geometry
-
Riantuan ning a dikthliar in a zorter
2. Zeicahdah Field Scanning nih Spot Stability a Hnorsuan
Hlathlainak hmun a karh tikah, mit hmuhnak nih laser ceunak kha a ngan deuhmi angle in a thlen a hau. Mah nih hin mit hmuhnak lei harnak zeimawzat a chuahpi:
2.1 Off-Axis Aberration
Ceunak cu a laifang in aa hlat tikah, mit in hmuh khawhmi thlennak a karh i, hmunhma thlennak a chuahter.
2.2 Field Curvature
Focal plane cu a tluk ti lo, cu nih cun scan tuahnak hmun a kam ah defocus a chuahter.
2.3 Galvo Dynamic palhnak
A rang tukmi cawlcanghnak Galvanometer Scanners nih hmunhma tlawmpal a tlaiter khawh asiloah a hlei in a luhter khawh.
2.4 Lens Riantuannak Rikhiahnak
Tahfung Scan Lenses nih a kau ngaimi angle ah a ummi thlennak kha tling tein a tlawmter men lai lo.
3. Laser Spot Tthawnnak Tthanchoternak caah A Biapimi Lam
3.1 A ttha ngaimi F-Theta Lens hmang
A sangmi f-theta lens cu scan field chung vialte ah aa khatmi zoh khawhnak caah a biapi tukmi a si. Mah nih a bawmh:
-
Hmunhma ngan le hme cu aa khat peng
-
Thlennak cu a tlawmter
-
Lo a tluknak a tthancho
A sangmi system ah, telecentric asiloah a ttha bikmi F-theta suaisam nih a ttha ngaimi riantuannak kha a tthanchoter.
3.2 Beam Expander Settings kha ttha tein ser
Scanning system chung a lutmi aa tlakmi beam diameter nih a tthanchoter:
-
Biakhiahmi
-
Thazaang tlawmtam tthawnnak
-
Hmunhma a tlongmi tlukruannak
A dik lomi beam kauhnak nih loram tthennak ah aa tluk lomi hmunhma ziaza a chuahter tawn.
3.3 Galvo Scanner Calibration tthanchoter
Galvanometer scanner system a dikthliar in tahfung tuah cu a biapi tuk:
-
Aa thleng lengmangmi zulhnak palhnak kha zorter
-
A dikmi linearity thlennak
-
Servo parameters kha ttha tein ser
Angular palhnak hmete hmanh kha hmun nganpi zohfelnak ah a lang deuh.
3.4 Laser hram fek tein uk khawhnak
Laser chuahmi thlennak nih hmunhma tthatnak kha direct in a hnorsuan. Fian ter:
-
A fekmi thazaang peknak
-
Aw tlawmmi laser mawngtu
-
Khuacaan-ukmi laser hrampi
Mah nih hin pulse-to-pulse thazaang thlennak a zorter.
3.5 A sangmi Field Remhnak Software Hman
Tuchan laser uknak system hna nih hin a tanglei thil hna hi a tlawmtertu field remhnak algorithms an i tel tawn:
-
Geometric thlennak
-
Lens thlennak
-
Aa thleng lengmangmi zohfelnak tlaihnak
Mah nih hin a kam tlukruannak kha tampi in a tthanchoter.
3.6 Sehzung le Lungthawhnak Tthawnnak Tthanchoter
Lungthawhnak le hninhnonak nih hmun fek tein um khawhnak a hrawh khawh. A tha bikmi tuahsernak hna ah aa telmi hna cu:
-
A fekmi bunhnak sining
-
Optical lam lumnak zohkhenhnak
-
Hninhnonak thleidannak hmun
4. Spot Stability sang a herhmi hmannak hmun hna
A fekmi laser hmunhma riantuan ning cu a hleiin a biapi:
-
A dikthliar in electronics hmelchunhnak
-
PCB riantuannak
-
Semiconductor micro-machining
-
Sii lei thilri sernak
-
A nganmi riantuannak suaimi
Hi hmannak hna ah hin, a tlawmte hmanh a ttha lonak nih thilri rawhralnak asiloah riantuan tthannak a chuahter khawh.
5. Biadonghnak
Laser hmun ttha tein zohfelnak ah laser hmun tthatnak tthanchoternak caah system-level tthaternak lam, mit hmuhnak, zohfelnak uknak, laser hrampi fek tein um khawhnak, le seh thilri suaisamnak hna aa tel.
Thil vialte lakah, optical system—a bik in scan lens le system tahfung tthatnak—nih a donghnak riantuannak tuaktannak ah a biapi bikmi rian a ttuan.
A ttha ngaimi optical thilri pawl le a dikmi system remhnak fonh in, sertu hna nih hmun kau laser riantuannak hmanh ah a fekmi, a ttha ngaimi phichuak an hmuh khawh.
