摘要：

A novel CCD sensor and associated camera, capable of operating in a burst mode at 100 million frames per second (Mfps) has been developed. This camera, referred to as "the Zenith camera" is combined with a fast pulse source of laser illumination to provide effective three-dimensional (313) volumetric imaging of objects contained within a highly back-scattering media. Each 16-frame burst establishes an image data-cube. The Zenith sensor is equipped with a custom micro-lens-array to overcome sensor fill factor limitations. Camera performance is evaluated to address and quantify a variety of parameters critical to the lidar application. This includes fundamental signal-to-noise performance, as well as temporal resolution effects such as image lac, occurring between adjacent frames within a data-cube. Image processing methods aimed at overcoming any residual image lag or other performance limitations are presented.
