I would have assumed they'd choose to work in a nice narrow absorption band like the 5.6u CO2 where solar illuminance is almost blocked. I know they commonly do that with structured light. It does add cost for filters and I don't know how well these ToF or standard CMOS imagers work there. https://www.researchgate.net/publication/328024940/figure/fig6/AS:677338480136196@1538501486681/Radiation-transmitted-by-the-atmosphere.jpg https://www.researchgate.net/publication/328024940/figure/fi...
