The invention consists of an optical sensor based on the random laser phenomenon, for the characterization of materials capable of diffusing light, such as powders, biological tissues, liquid dispersions and diffusive surfaces.
Tactile sensor emulates the human sense of touch in sensing and locating a pressure over a large surface, reproducing human mechanoreceptors activity.
The invention is within the optical fiber sensor technology, and in particular, sensors that measure physical perturbations (temperature, mechanical vibrations, pressure), where the wavelength of the reflected light responds to these parameters, such as fiber Bragg grating (FBG) sensors or Fabry-Perot sensors.
The technology proposes a simple method which removes phase distorsions without increasing noise, and can be implemented in any interferometer with active phase control (fiber-optic, integrated, free-space).
The present invention relates to a method and a device for carrying out position measurements such as scans of surfaces for the study of their topography and physical properties with microscopic resolution, and mass measurements (microscopic masses) by means of probes in dynamic mode, oscillating at a given frequency.
It is the purpose of the present invention to provide a sensor that allows to accurately monitor the pH value and its variations over time.
The invention deals with a localization method that finds application in localizing RFID-UHF tags in relative motion with respect to the RFID-UHF reader
