A scanning laser sensor is used to measure range information D as shown in Figure 3. Laser L=15cm | Beam

A scanning laser sensor is used to measure range information D as shown in Figure 3. Laser L=15cm | Beam splitter Phase measurement D Reflecting surface -Outgoing beam Returning beam Figure 3 Object Explain the working principle of this sensor and show how range information can be obtained. The modulation wavelength of the emitted laser is 10 meters. If the phase differences between the outgoing and incoming beams are 70 degrees and 360 degrees, determine the range. What is the maximum working range of the sensor?
