摘要： A calibration strip and a laser calibration system using thereof are disclosed. The calibration strip is comprised of: a substrate; and a light impermissible layer, having a calibration pattern formed thereon while being formed on the substrate. The light impermissible layer is an opaque layer, being formed on the surface of the substrate by coating, electroplating or adhering. The substrate, manufactured by the principle for enabling the color or brightness of the substrate to have high contrast comparing with those of the light impermissible layer, can be a structure of a layer of transparent material and a light source; a layer of transparent material and a backlight source; or a metal film having a reflective layer formed thereon. Since, in the laser calibration system, the calibration strip with the calibration pattern is imaged by an imaging device and then the captured image is send to a processing unit where it is analyzed, the time-consuming and inaccurate off-line manual calibration is no longer required and the laser calibration system can be adapted for various lasers regardless of their spectra.

摘要： A programmable laser trigger device and the method for controlling the same are disclosed. The programmable laser trigger device comprises: an external signal module and a command executing module. The external signal module is capable of interfacing the inputs and outputs of waveform command and signals. The command executing module further comprises: a waveform command memory, for storing the waveform command; a waveform command decoder; a waveform generator; and a buffer memory, acting as a waveform trigger parameter buffer between the waveform command decoder and the waveform generator; wherein the waveform command decoder accesses the waveform command stored in the memory for pre-decoding an executing code while generating a sequence of waveform trigger parameters to be stored in the buffer memory, which provides the waveform generator with the sequence of waveform trigger parameters to be transformed into a pulse-width modulation (PWM) pulse train. With the aforesaid device and method, not only unequal pulse outputs can be generated with good flexibility for matching the needs of various manufacturing processes, but also through the instructions to an external feedback signal from the waveform command, the laser pulses outputted therefrom can be modulated in real time in response to the external feedback signal.
