The ability to observe biological specimens, nanostructures, and materials with detail is crucial for understanding their fundamental properties and behaviors. However, most of the samples in cell biology and other fields are not able by itself to induce enough variations in the light intensity. Thus, many relevant information is missed. To solve this problem, the most common approach was to add stains to the sample, but in addition of being a time-consuming process, in this way the samples were being affected, changing its properties or killing the cells. 

On that context interferometric microscopy appeared as a promising solution. By exploiting the wave nature of light and analyzing the interference patterns generated by the interaction of light waves with the sample, interferometric microscopy enables to encode information about the spatial distribution of the refractive index or non-uniform thickness in the intensity of the interference pattern.

Nonetheless, interferometric microscopy either requires bulky and complex systems or can be only applied to very restrictive situations. In this talk, after a brief introduction to interferometric  microscopy, we will present a recently approach that aims to overpass those drawbacks by non requiring any restrictions or a priori knowledge on any of the interferometric beams.
