<li>자료<br />
<ol><br />
<li>pulse를 사용하는 TOF(time-of-flight) 원리가 아닌 phase 측정을 이용한다.<br />
<ol><br />
<li>측정거리 D=c/2f x (phase shift)/2pi. 거리는 2f에 반비례한다. 10MHz이면 15m까지 0~360도 변화한다. 1도 분해능이면 4cm 분해능이 된다. 더 먼거리를 위해서는 변조 주파수를 바꿔야 한다.<br />
<li>연속 레이저는 펄스 레이저에 비해 파워가 낮아 먼거리까지 도달하지 못한다.<br />
<li>150MHz를 LD로 사용하고, 150.005MHz를 발생시켜, 두 주파수 차이를 위상측정기 ref.로 사용하고, 반사되어 APD에서 측정된 주파수(150MHz)와 150.005MHz를 믹싱시켜 나온 5kHz를 위상 측정기 테스트로 넣어, 두 위상차이를 분석한다.<br />
<li>APD는 높은 전압이 필요하고, 특성이 온도에 크게 의존한다.<br />
