Abstract
A Novel method of refractive index evaluation using self-interference incoherent digital holography is proposed. Self-interference digital holography is a powerful phase detecting solution that can record not only the intensity of the image but also phase information under incoherent lighting conditions like LEDs. The proposed system using structured patterns and an autofocus algorithm to evaluate the numerically reconstructed hologram image to find a focused depth plane. The focused depth plane indicates the optical path difference between air and refractive media. To demonstrate a proposal, the experiment is conducted by measuring the refractive index of acryl.
