고출력 레이저에 의한 영상 센서의 손상 분석 연구를 수행하였다. 고출력 레이저에 의한 금속의 손상에 관한 연구는 많이 이루어져 있지만, 상대적으로 고출력 레이저에 취약한 영상 시스템의 손상 연구는 미비한 상태이다. 본 논문에서는 CMOS 영상 센서에 고출력 레이저가 조사 되었을 때, 영상 센서가 받는 손상에 대해 실험적으로 분석하였다. 고출력 레이저 소스로는 근적외선대역의 연속발진 광섬유 레이저를 사용하였으며, 레이저 세기와 조사시간에 따른 CMOS 영상 센서의 영구적 손상 및 영상 품질을 분석하였다. 그 결과 조사시간과 레이저세기가 증가함에 따라 먼저 색상 손상이 나타나고 이후 작동 불능 상태가 되었으며, 이러한 손상은 조사시간보다 레이저 세기에 더 큰 영향을 받는 것으로 나타났다.
영어 초록
This paper presents the results of an experimental analysis of the high-power laser (HPL)-induced damage to a complementary metal-oxide semiconductor (CMOS) image sensor. Although the laser-induced damages to metallic materials have been sufficiently investigated, the damages to electric-optic imaging systems, which are very sensitive to HPLs, have not been studied in detail. In this study, we experimentally analyzed the HPL-induced damages to a CMOS image sensor. A near-infrared continuous-wave (CW) fiber laser was used as the laser source. The influences of the irradiance and irradiation time on the permanent damages to a CMOS image sensor, such as the color error and breakdown, were investigated. The experimental results showed that the color error occurred first, and then the breakdown occurred with an increase in the irradiance and irradiation time. In particular, these damages were more affected by the irradiance than the irradiation time.
