Abstract

The invention relates to a transmitting module of a correlated imaging laser radar. The transmitting module is characterized in that the transmitting module comprises a speckle light source, an imaging system, a data memory and a synchronous controller, wherein the speckle light source and the imaging system are fixed on a same base. The transmitting module disclosed by the invention has the characteristics of high pulse transmitting speed, high utilization rate of light energy, capability of effectively reducing ghosting strength of a reference light field, and the like.

Description

technical field [0001] The invention relates to an associated imaging laser radar, in particular to a transmitting module of an associated imaging laser radar. Background technique [0002] Correlative imaging (including ghost imaging and compressed sensing) is a new imaging regime. It uses the fluctuation of the light field to encode the target, and only uses a detector without spatial resolution to receive multiple target reflection signals, and a clear image of the target can be obtained through the correlation algorithm. [0003] Zhao Shengmei from Nanjing University of Posts and Telecommunications's master thesis "Research on Thermal Light Ghost Imaging and Compressed Sensing Application" introduced the ghost imaging algorithm in detail, David L. Donoho's article "Compressed Sensing", IEEE Transactions on Information Theory, V52, NO. 4, 2006. The formulation and proof of compressive sensing algorithms are described in detail. [0004] Applying correlative imaging to l...
