We have developed the low-coherence single-shot interferometry to measure the group refractive indices of thin glass samples. In this method, two interference fringes can be observed on a single image. The group refractive index can be obtained from the interval of both fringes. The results were in good agreement with the minimum deviation method. Our method would contribute to digital transformation technologies such as AR/VR and aerial display devices.
