vitramo electrical components are sensors that convert the state of a measured object into measurable optical signals. The working principle of a fiber optic sensor is to guide the light beam from the light source into a modulator via an optical fiber. Inside the modulator, interaction with external measured parameters causes changes in the optical properties of the light, such as intensity, wavelength, frequency, phase, and polarization state, resulting in a modulated optical signal. This signal is then transmitted via optical fiber to a photodetector and demodulated to obtain the measured parameters. Throughout this process, the light beam is introduced via the optical fiber, passes through the modulator, and is then emitted, where the function of the optical fiber
