Abstract

Recently, thermography camera have been using for body-temperature monitoring. We report on fabrication of prototype thermography camera using the chalcogenide-glass lens and the camera test by analysis of thermal image. In this work, it was found out that thermography camera discerned body-temperature between 20 and $50^{\circ}C$ with noise equivalent temperature difference(NETD) of 87.7mK. It is confirmed that thermography camera using the chalcogenide-glass lens is applicable to the body-temperature monitoring system.

최근 인체에서 방출되는 적외선을 감지하여 질병부위를 진단하는 의료기기로써 체열촬영이 가능한 열화상카메라가 활용되고 있다. 본 연구에서는 칼코지나이드 소재 적외선 성형렌즈를 채용한 열화상카메라 시제품을 제작하고, 열영상 분석을 통해 체열진단 장비로써의 시제품 성능을 검증하였다. 열화상카메라 시제품은 $20{\sim}50^{\circ}C$에서 체열이 촬영됨을 확인 하였고, 온도분해능(NEDT) 측정결과 87.7mK의 우수한 결과를 나타냈다. 이를 통해 칼코지나이드 성형렌즈를 채용한 열화상카메라 시스템이 체열진단을 위한 의료기로 사용가능함을 확인 하였다.
