High-resolution, real-time three-dimensional imaging using an innovative single lens system
The present innovation is a method and instrument to simultaneously generate a topographic profile of an object, surface or landscape.
Scanning LiDAR systems are most often used to simultaneously (i.e. in as short a time as possible) to achieve high spatial resolution and height (or depth) resolution over the maximum possible optical field of view. The disadvantage of the scanning system is the time it takes to scan, which prevents simultaneous image acquisition. This can be a problem for systems involving moving observers or objects, or both. Diffraction grating systems are also commonly used for threedimensional imaging. These systems are limited by the grating throughput efficiency, and create difficulty generating a large number of spots and spots with equal energy. Flash LiDAR systems with uniform light distribution are also used, but these systems suffer from adjacent pixel crosstalk, reduced system measurement efficiency and difficulty in giving equal intensity weighting to each pixel. The present innovation overcomes the shortfalls of previously used threedimensional imaging systems by employing a simple lens system.
