Abstract
A laser machining system and a method thereof are disclosed. The disclosed laser machining system comprises a laser generator, an array photo detector, a processer, and a position controller. The laser generator is configured to emit laser via a first light path onto a work piece. The array photo detector is configured to receive the thermal radiation from the work piece via a second light path, different from the first light path, to generate a thermal radiation image. The processor, electrically coupled to the laser generator and the array photo detector, is configured to calculate a temperature centroid of the thermal radiation image and generate a distance control signal according to the temperature centroid. The position controller, electrically coupled to the processor, is controlled by the distance control signal to make a present distance between the laser machining system equal to a working distance.
