In this paper, we address quantitative phase imaging of hard-to-reach objects using conventional endoscopic probes. We present a scheme of digital holographic module compatible with commercially available rigid rod-lens endoscopes. In this scheme, a reference beam is obtained using a single-mode optical fiber. The module is a quite simple two-lens system located behind the endoscope eyepiece. It allows the registration of Fourier holograms as well as conventional imaging mode.
