I have heard of lense covers that fit over lights that show no visible light but send out infrared light instead. Do these exist ? and would they have any affect on LIDAR speed measurment equipment ?
I know from military service that some of the M113 APC's and other tracked vehicles had lights to aid in nightvision equipment use. Would these or a similar civilian version do anything for use against LIDAR equipment ?
Sorry if these are simple questions or have been asked before but I searched and couldn't find any posts on IR lense covers or lights.
