An optical sensor for pressure measurements comprises a sensor head including: a diaphragm having a first surface in contact with a fluid of which the pressure has to be measured and a second surface opposite to the first surface, a body with a tubular cavity, means arranged inside the tubular cavity, associated with the second surface of the diaphragm and movable longitudinally inside said tubular cavity in response to deformation of the diaphragm, said means including a reflective surface, an end part of waveguide means arranged inside the tubular cavity and having the end surface faced to and not in contact with the reflective surface of said means, said waveguide means being connected to a light source and a receiver respectively to send to said means the light beam deriving from the light source and to collect at the receiver the light beam reflected from the reflective surface.
