Abstract: An optical radar includes an optical-signal receiving unit and an optical-signal pickup unit. The optical-signal receiving unit is configured to receive a reflected light. The optical-signal pickup unit is coupled to the optical-signal receiving unit and includes a first optical-signal filtering circuit and a second optical-signal filtering unit. The first optical-signal filtering circuit is configured to filter out a first interference pulse of the reflected light, wherein the first interference pulse has a first interference voltage value higher than a reference voltage. The second optical-signal filtering circuit is coupled to the first optical-signal filtering circuit and configured to generate a clock signal comprising a clock pulse; and filter out a second interference pulse that does not match the clock pulse in time point from the reflected light.

Abstract: A laser automatic compensation control device includes a controller, a digital array, a decoder, a compensation array and a synchronizer. The controller is configured for receiving a number of laser energy signals and comparing each laser energy signal with a corresponding preset energy value to obtain a corresponding output digital signal. The digital array is electrically connected to the controller and configured for storing the output digital signals. The decoder is electrically connected to the digital array and configured for converting the output digital signals into a number of analog compensation signals. The compensation array is electrically connected to the decoder and configured for storing the analog compensation signals. The synchronizer is electrically connected to the compensation array and configured for receiving the analog compensation signals, and synchronously outputting the analog compensation signals to a laser diode array.
