Abstract

We present a hybrid optical device for measurement of refractive index variation in a selfoc lens by the Talbot effect. The intrinsic nature of the device that combines a linear grating and an inhomogeneous medium permits to measure changes in the refractive index along the axis as a function of the position shift of the first self-image. Possible changes in the temperature during lens fabrication can be extracted from refractive index variation. The hybrid device has a refractive index sensitivity of ±7 x 10^-5 per nanometer of position shift of the first self-image.
