20090130467TRANSFER COMPONENT AND LASER-ASSISTED TRANSFER SYSTEM USING THE SAME - A transfer component and a laser-assisted transfer system using the same are provided. The laser-assisted transfer system comprises: a multimode laser source; a beam transformer; a scanner module; and a transfer component. The beam transformer is capable of transforming a multimode laser beam generated from the multimode laser source into a rectangular beam and then feeding the rectangular beam into the scanner module to form a large-area scanning laser beam. The transfer component comprises a conductive thin film and an insulating thin film. The conductive thin film receives a scanning laser beam from the scanner module and is ablated while the ablation of the conductive thin film is transferred onto the insulating thin film. In an exemplary embodiment, the transfer component comprising a metal thin film and an organic thin film is used for enabling the system to perform large-area pattern transfer with high efficiency.05-21-2009

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.05-28-2009
20090139297CALIBRATION STRIP AND THE LASER CALIBRATION SYSTEM USING THEREOF - 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.06-04-2009
