【Abstract】 A three-dimensional control system applied in optics measurement is introduced in this paper. The control interface for the system is programmed in Visual Basic language. By means of data sampling card, the computer can control the movement of the three motorized stages, and can do real time sampling of the light intensity in three-dimension. By using of the data saved in the computer when sampling, which represents of the light intensity in three-dimension, the programme automatically calculates the angle of refraction. Aiming at the problem of response time delay of temperature sensing detector, a method of eliminating the error caused by the response time delay is introduced.更多还原
