Abstract

Apparatuses, systems and methods for modulating returned light for acquisition of 3D data from a scene are described. A 3D imaging system includes a Fabry-Perot cavity having a first partially-reflective surface for receiving incident light and a second partially-reflective surface from which light exits. An electro-optic material is located within the Fabry-Perot cavity between the first and second partially-reflective surfaces. Transparent longitudinal electrodes or transverse electrodes produce an electric field within the electro-optic material. A voltage driver is configured to modulate, as a function of time, the electric field within the electro-optic material so that the incident light passing through the electro-optic material is modulated according to a modulation waveform. A light sensor receives modulated light that exits the second partially-reflective surface of the Fabry-Perot cavity and converts the light into electronic signals. Three-dimensional (3D) information regarding a scene-of-interest may be obtained from the electronic signals.
