Really bright LEDs can be used for underwater optical communication up to 100 m[0]. I'd really like to see someone make this tech into an FPV system for RC subs

- anfractuosity 3y agoCool, that's very interesting! I also just found this using an array of ultrasound transducers https://group.ntt/en/newsrelease/2022/11/01/221101a.html https://group.ntt/en/newsrelease/2022/11/01/221101a.html for standard definition video.
- ethbr1 3y agoIt'd be kind of sketchy to have as a single point of failure in an underwater ROV that might not be able to emergency-surface straight up (e.g. wreck or overhang exploration). There's a ton of gnarly stuff that can happen underwater acoustically without obvious warning (salinity, temperature, topography, etc etc).
