Three-dimensional imaging system with configurable light pulse divergence
The patent application (Publication Number: US20240031549A1) describes a method for three-dimensional imaging with high dynamic range. The method involves emitting a light pulse with a predetermined divergence to illuminate a scene, receiving a portion of the reflected or scattered light pulse, modulating the intensity of the received light pulse over time, and recording first and second images using focal plane arrays (FPAs) with filters. These images are then used to generate a three-dimensional image.
Furthermore, the method includes additional steps such as selecting information from pixels in the FPAs based on a stored map of the filter, calculating time of flight measurements for the light pulse, and utilizing filters with different levels of attenuation or sensitivities. The generated three-dimensional image benefits from increased dynamic range and resolution due to the use of filters in the FPAs. Overall, this method offers a comprehensive approach to three-dimensional imaging with high dynamic range, leveraging the capabilities of FPAs and filters to enhance the quality and accuracy of the final image.
