- 摘要：
- A set of laser detecting system for liquid-level with inclination measurement-based high-resolution and a sinking-block device are developed to detect and control the liquid-level of Stereolithography Apparatus precisely. A brightness-variable laser source is adopted to eliminate the computational error of divider, a closed-loop circuit is set to measure the terminal voltage directly which proportional to the output current of PSD, and hence the position of laser beam can be indicated accurately. A sinking-block device is employed to control the liquid level. The precise calibration result of this detecting device indicates that the resolution of the liquid-level detection can reach ±1.5μm. Compared with overflow liquid-level control, this liquid-level control device of sinking-block style can allow the liquid-level wave reduce from ±45μm to ±15μm. This system works stable with the high precision and antijamming ability. It has applied successfully in Stereolithography Apparatus.
