Title: The Dispersion Coefficient of Air Refractive Index Measurement System Based on CCD Imaging Technology
Abstract: In order to measure the dispersion coefficient of air refractive index and other transparent material rapidly and accurately, this paper studies the dispersion coefficient measurement system based on CCD imaging technology. On the basis of consideration of the air refractive index impacting on the measurement accuracy of dispersion coefficient by using the measuring angle technology of precision grating. The paper realizes the digital measurement of deflection angle of refracted ray. Finally, the multichannel small collimator designed technology and the modern control technology are combined to achieve the high precision measurement of dispersion coefficient of optical glass in this paper.
