Abstract
범죄현장에서 증거를 찾는 감식의 가장 중요한 방법 중 하나는 빛의 특정 파장을 이용하여 지문 등 잠재증거를 찾는 방법이다. 지금까지는 가시광선을 이용하여 현장에서 증거물을 감식하였으나 여러 종류의 증거물과 미세한 증거에 적용하기에는 한계가 있었다. 그래서 다양한 빛의 파장에서도 증거물의 이미지를 얻을 수 있는 촬영장비를 개발하였다. 일반적인 카메라의 센서는 가시광선만을 이미지화 하도록 설계되어 있지만, 이번에 개발된 장비는 360~1,000 nm의 자외선부터 적외선까지 전체 빛의 파장 영역에서도 이미지를 얻을 수 있는 새로운 CMOS 센서를 탑재하였다. 또한 적외선 영역에서 650~1,000 nm까지는 장비의 내부에 장착한 정밀광학 필터가 광원의 파장 영역에 따라 각각 독립적으로 인식되면서 제어할 수 있기 때문에 이미지는 최대 4 K까지 선명도가 높아졌음을 확인할 수 있었다.One of the most important ways to find evidence such as fingerprints in a crime scene is searching for the potential evidence using the specific wavelengths of forensic light source. Until now, evidence was discerned in the field using visible light, which is a wavelength of visible light, but it was limited to apply to various types of evidence and fine evidence. So, the authors developed an imaging device that can obtain images of evidence even at various wavelengths of light. Although the sensor of a typical camera is designed to image only visible light, the newly developed equipment was used a new CMOS sensor that can acquire images in the entire wavelength range of light from ultraviolet rays to infrared rays from 360 to 1,000 nm In addition, since the precision optical filters mounted inside the equipment from 650 to 1,000 nm in the infrared region can be independently controlled and controlled according to the wavelength range of the light source, it was confirmed that the image has increased clarity up to 4 K.
