【Abstract】 Using the linear charge-coupled device(CCD) array to measure the displacement of the refractive ray spot on the basis of the refraction law,we have designed a pint-sized apparatus to measure the refractive index of some transparent material.The designed measurable range of the refractive index is improved greatly.The designing principle and usage of the apparatus are explained in this paper.Measurement of the refractive index of some materials shows that the apparatus is of high measuring accuracy.更多还原
