    • A system, method, and communication device are disclosed. The system can include an optical interrogator and a phase-modulating communication device. The communication device can include a retro-optimized lens, a phase modulator, and a processor. The retro-optimized lens can be a non-imaging optical arrangement configured to minimize deviation between an incoming signal and a reflected signal used for return link communications. The processor can be configured to calibrate a modulation path length of the communication device based on a wavelength of the communication signal and can control an operation of the phase-modulator to send phase-coded messages to the interrogator. Optionally, the processor can perform a real-time phase calibration of the communication device using feedback from the interrogator.
    • 公开了一种系统,方法和通信设备。 该系统可以包括光学询问器和相位调制通信设备。 通信设备可以包括复现优化的镜头,相位调制器和处理器。 复现优化的透镜可​​以是非成像光学装置,其被配置为最小化用于返回链路通信的输入信号和反射信号之间的偏差。 处理器可以被配置为基于通信信号的波长来校准通信设备的调制路径长度,并且可以控制相位调制器的操作以将相位编码的消息发送到询问器。 可选地,处理器可以使用来自询问器的反馈来执行通信设备的实时相位校准。
