Communication with Ambient Light using Digital Micromirror Devices

Passive visible light communication (VLC) takes advantage of the pervasive<br/>nature of ambient light in our environment for wireless transmissions. The<br/>design of transmitters in passive VLC predominantly uses Liquid Crystal Displays (LCD’s). While LCD’s are an economical choice with low power consumption, they lack some key properties that...

Passive Localization with Visible Light

Indoor localization is a topic of significant interest for academic and in dustrial. For outdoors, we have Global Positioning System (GPS) working very well, but GPS does not work indoors and we spend more than 90% of the time indoors. Thus, there is a great need to find solution for this prob lem. Many technologies have been proposed for indoor...
