Abstract: 레이저 용접에서 고출력 레이저빔은 렌즈에 의해 용접 대상체에 집속된다. 집속 렌즈는 레이저빔의 크기를 제한하는 구멍(aperture)의 상을 용접 대상체에 맺게 하므로, 집속된 레이저빔의 크기는 용접 대상체에 맺히는 구멍의 상의 크기와 같다. 레이저빔이 집속되는 영역에 용접 대상체가 녹아 용접 풀(pool)이 생성되며, 이 용접 풀에서는 열복사(thermal radiation)가 방출된다. 이 용접 풀의 크기는 열전도 등에 의해 집속된 레이저빔의 크기와 반드시 같지는 않으며, 레이저의 출력이나 집속 렌즈의 초점위치에 의해 영향을 받는다. 본 발명은 용접 풀에서 방출되는 열복사 신호를 이용하여 집속 렌즈의 초점과 레이저 출력 등 레이저 용접의 상태를 실시간으로 감시하는 방법 및 장치에 대한 것이다. 본 방법 및 장치는 용접 풀에서 방출되는 열 복사 신호를, 레이저빔 집속 렌즈와 레이저빔의 크기를 제한했던 구멍이나 또는 다른 구멍을 통하여 최소한 3개 파장이상에서 단일 광검출 소자를 사용하여 검출하는 방식으로 구성된다. 집속 렌즈의 색수차 때문에, 각 파장에서 검출되는 열복사 신호는 용접 풀의 크기와 초점이동에 대해 서로 다른 특성을 보인다. 본 방법 및 장치의 신호처리 알고리즘은 이 3개 이상의 열복사 신호를 이용하여, 용접 풀의 크기와 집속 렌즈의 초점위치를 레이저 출력의 영향을 받지 않고 서로 독립적으로 측정할 수 있다.
