我们提出了一种名为“智能光”的空间复用光传输系统（见图1），它可以同时向多个点提供多个数据流。该系统由一个投影仪和一些设备以及一个光电探测器组成。投影仪将带有不可见信息的图像投射到设备上，设备接收到一些数据。在该系统中，数据流通过使用dmd（数字微镜设备）或led（发光二极管）进行不可感知的时空调制，可扩展为基于位置的音频或视频流。首先，在初步实验中，我们用商用的XGA级投影仪传输100万个点，确认其路径的数据速率为每秒几比特。分离的设备可以从投影仪接收相对位置数据和其他属性。其次，我们制作了一个LED型高速投影仪，利用调制光在物体上传输音频流，并确认了基于位置的音频流数据的传输。
We present a spatial multiplex optical transmission system named the “Smart Light” (See Figure 1), which provides multiple data streams to multiple points simultaneously. This system consists of a projector and some devices along with a photo-detector. The projector projects images with invisible information to the devices, and devices receive some data. In this system, the data stream is expandable to a positionbased audio or video stream by using DMDs (Digital Micro-mirror Device) or LEDs (Light Emitting Diode) with unperceivable space-time modulation. First, in a preliminary experiment, we confirmed with a commercially produced XGA grade projector transmitting a million points that the data rate of its path is a few bits per second. Detached devices can receive relative position data and other properties from the projector. Second, we made an LED type high-speed projector to transmit audio streams using modulated light on an object and confirmed the transmission of positionbased audio stream data.
