Title (EN) DEVICE AND METHOD FOR ADJUSTING LASER FOCUS
(FR) DISPOSITIF ET PROCÉDÉ D'AJUSTEMENT DE FOYER LASER
(KO) 레이저 초점 조정 장치 및 방법
Abstract:
(EN) One embodiment relates to a device and a method for adjusting a laser focus, which can determine an optimum focal position, and according to the one embodiment, the device for adjusting a laser focus comprises: a laser generation unit for generating a laser; a steel plate at which the laser generated by the laser generation unit is emitted; a support roll for adjusting the distance between the laser generation unit and the steel plate by changing the position of the steel plate; and an analyzer for analyzing the spectrum of radiant light of a region , of the steel plate, at which the laser is emitted .
(FR) Un mode de réalisation concerne un dispositif et un procédé pour ajuster un foyer laser, qui peut déterminer une position focale optimale, et selon le mode de réalisation, le dispositif de ajuster un foyer laser comprend : une unité de production de laser pour produire un laser ; une plaque en acier au niveau de laquelle le laser produit par l'unité de production de laser est émis ; un rouleau de support pour ajuster la distance entre l'unité de production de laser et la plaque en acier grâce à modification de la position de la plaque en acier ; et un analyseur pour analyser le spectre de lumière rayonnante d'une région de la plaque en acier, au niveau de laquelle le laser est émis.
(KO) 실시 예는 최적의 초점 위치를 결정할 수 있는 레이저 초점 조정 장치 및 방법에 관한 것으로, 실시 예의 레이저 초점 조정 장치는 레이저를 발생하는 레이저 발생부; 상기 레이저 발생부에서 발생하는 레이저가 조사되는 강판; 상기 강판의 위치를 변경하여 상기 레이저 발생부와 상기 강판 사이의 거리를 조절하는 서포트롤; 및 상기 강판의 상기 레이저가 조사된 영역의 복사광의 스펙트럼을 분석하는 분석기를 포함한다.
