Do tomorrow PLS HELP I WILL GIVE Brainliest In fiber-optic communications, the Mach-Zehnder modulator turns light into a digital signal of light pulses. In contrast, in LiDAR, the modulator is used to create pulses that allow a detector to probe distance and shape, by measuring pulse time of flight. What other technologies, or their specific applications, utilize light as a signal carrier or a visual probe? Are there other roles for light you can discover, in modern technology? Are there any examples where light plays a dual role?
