| Abstract: | Aiming at the requirement of liquid-level measurement for stereolithography(SL),the paper put forward a new method of laser liquid-level measurement based on position sensitive detector(PSD),which could carry out non-contact precision measurement,using laser triangular surveying theory.The measurement system according to the way achieves online automatic measurement making use of special signal integrated processing circuit,fulfils data acquisition,processing,analyzing and display by computer.Its measurement accuracy reaches 0.01mm. |
