  • Tunable optical filter based upon liquid crystal cell and wavelength sweeping method
    Patent number: 11009398
    Abstract: A tunable optical filter, includes a light source configured to emit optical radiation to a sample; an input optical element configured to receive optical radiation reflected from the sample; a liquid crystal cell comprising electrodes, the liquid crystal cell contacting the input optical element; an output optical element, contacting the liquid crystal cell; and a control unit adapted to apply a preset voltage to the liquid crystal cell via the electrodes; wherein the input optical element and the output optical element have a same first refractive index, wherein, when voltage is not applied to the liquid crystal cell, the first refractive index is greater than a second refractive index of the liquid crystal cell for a wavelength range of incident optical radiation, and wherein the input optical element, the liquid crystal cell and the output optical element are tilted at an angle to the incident optical radiation.
