A Practical Method to Measure Parameters of Lenticular-Lens Sheet for 3DLCD

Nowadays, with the rapid development of stereoscopic display technology, grating has been more and more widely used in auto stereoscopic 3DTV. This paper introduces a method that can be used to measure the parameters of lenticular-lens sheet for 3DLCD. This method is mainly based on the pure white-black characteristic image, by making use of the iterative method to get close to the accurate values of lines per inch, slant angle and k-offset. Compared with other methods, the one introduced in this paper is much simpler but more accurate, and experiments show that the parameter values measured using this method are close enough to the nominal values and can be used to improve 3D display qualities.
