Design of a LabVIEW-Based Optical Lab Integrated Measurement and Control System

Based on the powerful virtual instrument technique of LabVIEW, we design an optical lab integrated measurement and control system for the needs of measurement and control in nonlinear optics experiments. This system has the advantages of good human-computer interaction and manipulation convenience. By a modularized design, the laser controller, the signal generator, the tunable laser, the power meter, the spectrographs and the oscilloscope are integrated into one virtual instrument. This virtual instrument can automatically change the key system parameters, and can real-time parallel fetch various data, such as data of optical spectrum, frequency spectrum and time series. Hence, high automated tests can be realized. The results indicate that this system can significantly improve the efficiency in experiments and provide a strong support for accomplishing research tasks.
