Résumé

This paper presents a digital holographic method to visualize and measure refractive index variations, convection currents, or thermal gradients, occurring inside a transparent and refracting object. The proof of principle is provided through the visualization of refractive index variation inside a lighting bulb. Com-parison with transmission and reflection holography is also provided. A very good agreement is obtained, thus validating the proposed approach.
