Development of Numerical Calculation Software for OTF from Lens Design Data

광학설계제원으로부터의 OTF 수치계산 S/W 개발

A software to calculate diffraction OTF from lens design data was developed and its accuracy was verified. To verify the accuracy, MTF of a standard lens system for OTF measurement were calculated. The results were compared with calculated values by another commercial software and measured values. We found that they have good agreements with one another.

광학설계제원으로부터 회저로광학적인 방법으로 OTF를 계산하는 S/W를 개발하고 계산정밀도를 검증 하였다. 개발된 S/W를 이용하여 OTF측정용 표준렌즈에 대한 MTF를 계산하여 본 결과 다른 S/W에서의 계산치 및 실험을 통한 측정치와 잘 일치하고 있음을 확인할 수 있었다.
