激光技术光学拾音器光学隧穿效应全反射 laser technique optical pickup optical tunneling effect total internal reflection

摘要

为了探索新型高灵敏度光电拾音器技术方案, 基于光学隧穿效应研究, 将声压变化转换为全反射棱镜中全反射面与摆片光学面之间的光学隧穿距离变化, 从而改变光束在棱镜全反面处的反射(透射)损耗, 通过直接测量反射(透射)光的功率变化, 实现拾音器基本功能。利用半导体激光器和直角全反射棱镜搭建了一套简易的原理验证实验系统, 并利用该系统对三角波信号驱动进行了实验。结果表明, 反射光功率会随着三角波信号的改变而改变, 光功率改变达到5.6%;由声音引起的玻璃振膜距离变化也可改变输出光功率, 并被检测出来。初步验证了该方案的可行性。

Abstract

In order to explore new high sensitivity schemes of photoelectric pickup, based on the optical tunneling effect, the change of sound pressure was translated into the change of the optical tunneling distance between the total reflection surface and pendulum optical surface of the total reflection prism. The reflection (transmission) loss of the beam at the whole opposite side of the prism was changed. The sound signal was recorded by measuring the power change of the reflected or transmitted light. To demonstrate this scheme, a set of simple experimental system was built with a semiconductor laser and a rectangular-prism, using triangular wave signal to drive the pendulous reed in the experimental apparatus. The results show that the power of the reflected light changes with the change of triangular wave signal. The variation of the power is up to 5.6%. The change of tunneling distance caused by sound signal can also affect the power of the transmitted light. The feasibility of the scheme is verified.
