3d imaging system using electro-optic modulation for light
The granted patent US12066546B2 describes a 3D imaging system that integrates an intensity modulator with an angular acceptance equivalent to at least an f/3.5 lens. Central to this system is a Fabry-Perot cavity featuring two partially-reflective surfaces designed for high-contrast light transmission, achieving a reflectivity of at least 80%. The system incorporates an electro-optic material positioned within the cavity, allowing some incident light to pass through while maintaining a finesse that enhances angular acceptance. The design includes electrodes that generate an electric field within the electro-optic material, modulated by a voltage driver to temporally alter the light passing through. A light sensor captures the exiting light and converts it into electronic signals for further processing.
Additionally, the patent outlines various configurations and materials for the electro-optic component, including options such as potassium iodate, lithium niobate, and various polymers. The system can utilize transparent longitudinal or transverse electrodes, which may be segmented for enhanced performance. The processor subsystem linked to the light sensor is responsible for generating 3D image data based on the received signals and can also control the voltage driver for electric field modulation. The patent further details methods for capturing 3D data, emphasizing the role of the electro-optic material in modulating incident light and the subsequent generation of 3D data from the electronic signals produced by the sensor.
