摘要

Streak tube imaging lidar has been widely applied in target recognition and imaging because of its high accuracy and frame rate. Compressed ultrafast photography technique employs a digital micromirror device (DMD) and a streak camera. It is developed to satisfy the requirements of imaging of ultrafast processes. The concept of structure provides a new direction for three-dimensional (3-D) imaging. This paper studies the streak tube 3-D imaging system based on compressive sensing (CS) from the perspective of imaging system construction and image reconstruction algorithms. The system model is built, and mainly structures are introduced such as the fiber array and DMD. Two simulation experiments are organized. First, the stripe images of a simple target are obtained. In the process of reconstructing the intensity image and range image, the extraction methods of the measurement matrix required by the CS algorithm are given, respectively. The resulting images and variance curve show that the image quality increases with the number of measurements. The second experiment with a complex target is carried out. Two levels of distance interval are used to analyze the imaging effect in the simulation. It is found that the image resolution is directly related to the distance interval selection
