Imaging lidar for space and industrial applications

A new time-of-flight-based imaging lidar was designed to carry out measurements in the 5 to 100-m range. The concept of the device, along with an illustration of the design of a time-to-digital converter for parallel time interval measurements and a presentation of our sensor breadboard is described. Test results showing sensor performance are also presented and discussed. This lidar can be used for shape and profile measurements in space and industrial applications.
