摘要

本文演示了一种基于光纤散斑图准分布式传感器的简单钢琴界面,以演奏满C大调音阶。用户通过泡沫垫在连接到激光源和网络摄像头的多模光纤上输入音符。关联参考和即时斑点图检索笔记输入,随后通过连接到网络摄像头的音频输出播放。实验证明,该接口对8个音符加一个中性状态的输入精度可达~ 0.94%,且不依赖于输入顺序。

Optical Fiber Speckle-Based Musical Interface
This paper demonstrates a simple piano-inspired interface to play a full C major scale based on a optical fiber specklegram quasi-distributed sensor. The user inputs musical notes via foam pads over one multimode optical fiber connected to a laser source and a webcam. Correlating the reference and immediate specklegrams retrieves the note input, subsequently played via audio output connected to the webcam. The interface is demonstrated with a precision of ~0.94 % for eight musical notes plus a neutral state and does not depend on the input order.
