<li>Chiba Precision 회사 및 제품 설명에서<br />
<ol><br />
<li>회사 역사<br />
<ol><br />
<li>1979년 Chiba Precision Co., Ltd. 설립<br />
<li>2007년 Citizen이 인수하여, 회사이름을 Citizen Chiba Precision Co., Ltd. 로 변경<br />
</ol><br />
<li>기술<br />
<ol><br />
<li>선택은 스캐너 거울면적과 스캔 각도로 결정된다.<br />
<li>스캔각도: +-10도 이내로 선형성을 유지한다. +-20도까지 기계적으로 돈다.<br />
</ol><br />
<li>용어<br />
<ol><br />
<li>스캐너:scanner라고 함은 아래 3가지로 구성된다.<br />
<ol><br />
<li>거울:mirror<br />
<li>모터:motor - 코어리스 모터 구조로 응답이 빠르고 정확한 각도제어가 가능하다.<br />
<li>엔코더:position detector<br />
<ol><br />
<li>2022년도에는 optical analog sensor를 사용한다. 디지털 엔코더 제품은 만들지 않는다.<br />
<ol><br />
<li>고해상도 디지털 엔코더는 노이즈와 온도변화에 무관한 장점이 있다.<br />
<li>거울반사형 아날로그 엔코더에 비해 무거워 관성이 크고, 신호 변환에 시간이 오래 걸려 고속동작에 불리하다. 그리고 가격이 비싸다.<br />
</ol><br />
<li>거울에 레이저 광선을 조사하여 각도(수광소자에서 해당되는 전압으로)를 검출한다.<br />
<li>모터와 엔코더 선형성을 교정해야 하므로 드라이버에서 이를 보정하므로, 드라이버와 함께 짝을 맞춰 공급한다.<br />
</ol><br />
</ol><br />
</ol><br />
<li>Galvanometer Optical Scanner 모델명, SCM2242-2400 (2022년 생산모델 2260과 모터 직경이 유사)<br />
<ol><br />
<li>4자리 번호에서 첫 두자리는 스캐너 거울 직경이다. 즉, 22이다. 약 10mm 정도의 레이저 빔 직경을 사용한다.<br />
<li>-2400에서 2는 +-20도 각도이다.<br />
<li>2022년 생산모델 2260은 반복성 9urad을 갖는다. (pi 라디안은 180도이므로 0.5밀리도를 갖는다.<br />
