The Design and Construction of light transducer at low level

미광증폭소자의 설계 및 제작에 관하여

This paper was studied as the following steps. 1) The relation between the brightness and the AC voltage on the EL cell made from ZnS powder was investigated. 2) The relation among the photocurrent, the applied AC voltage and the illumination on the protoconductive cell which was made of CdS powder, was examined. 3) From the above relations approximate equations were made. Also the theoretical gain equation of the light amplifier was derived. 4) Comparing the theoretical gain value to the experimental gain value of the light amplifier which was composed of EL and PC cells, it was come to the conclusion that the gain equation was correct within 2% errors and was useful to comprehensibility of the light amplifier and to design of it.

먼저 ZnS분말을 공기중에서 소성하는 방법을 연구하여 EL을 제조하여 만들어진 EL의 전기광학적 실험을 하였다. 다음에 CdS를 이용하여 광도전소자를 만들고 그 전기광학적 성질을 조사하였다. 위의 두가지를 이용하여 하나의 미광증폭소자를 만들어 그 원리를 이론적으로 규명하였고 실험적으로 확인하였다. 결론적으로 우리가 세운 이론식이 2%이내의 오차한계에서 정확하였고 미광증폭기의 설계와 제작에 도움이 됨을 알았다.
