我们展示了一个条码传感系统的太赫兹区域使用泄漏平行板波导和离轴抛物面镜。条形码的条由金属制成，其间有空气作为间隙。我们在条码系统中使用多达6条条码，可以存储多达64位。由于该系统采用相干检测，我们可以通过在条形码上添加Teflon条来进一步增加位密度，以幅度和相位延迟对信息进行编码。这些条形码可以轻松且廉价地制造，为RFID标签提供了多功能的替代品。(C)根据OSA开放获取出版协议的条款，2021年美国光学学会
We demonstrate a bar code sensing system for the THz region using leaky parallel plate waveguide and an off-axis parabolic mirror. The bars of the bar code are made from metal with air as gaps between them. We use up to 6 bars in the barcode system which can store up to 64 bits. Because the system employs coherent detection, we can further increase the bit density by adding Teflon strips to the barcode, encoding information in both amplitude and phase delay. These bar codes can be manufactured easily and inexpensively, offering a versatile alternative to RFID tags.
