Tx & Rx Electronics

The transmitter & Receiver Electronics project is used to detect the objects within the range 10 KM and calculate distance from the objects to the source by using laser light. The design implemented measures the range information based on the time taken for a light pulse to reach a target and echo back. This design comprised of a light emitting circuit that outputs short and powerful pulses of laser beam toward a measurement target object; a light receiving circuit that photo-electrically converts the laser light reflected from the target object and amplifies the converted optical signal; a time to digital converter (TDC) to calculate the TOF of the laser light
