Abstract
The system includes a laser generator, an antenna, and a processor to distinguish the photovoltaic radio frequency signals emitted by defective LEDs and functioning LEDs in a contactless manner. The laser generator emits a pulsed laser beam toward an LED. The LED generates a photovoltaic radio frequency signal when radiated by the pulsed laser beam. The antenna receives the photovoltaic radio frequency signal generated by the LED. The processor is in electronic communication with the antenna and is configured to read the photovoltaic radio frequency signal and determine whether the LED is a defective LED or a functioning LED based on the photovoltaic radio frequency signal, such as by using the frequency, amplitude, or phase shift of the radio frequency signal.
