A dual-confocal auto-focus sensing module for measuring defocusing positions of specimens in laser machining systems or inspecting devices is proposed. This sensing module can improve the detecting accuracy by analyzing and fitting signals from the difference between the dual optical paths, and miniaturize the optical apparatus with the superior integrated optical design. This auto-focusing module...
In order to improve the imaging quality of conventional laser photography, this study proposes a new system for colored pulse laser photography to obtain high speed color microscopic imaging. Based on the RGB synthesis technique, three channels of red, green, and blue images are acquired from three cameras with three independent laser light sources. Then, a high quality color image can be obtained...
Based on the RGB synthesis technique, a novel colored pulse lasers photography is designed for high speed imaging. A high quality color image can be acquired by assembling the three channels of red, green, and blue images which are acquired from three cameras with three independent laser light sources.
A self mode-locking (SML) ring cavity laser system with the Yb-doped fiber (YDF) was demonstrated. When the gain fiber was disturbed, the phenomenon of SML was observed. The system can produce the laser pulse width which is smaller than 1 ns without any modulation process such as polarization controller and dispersion compensation.
