High resolution, high signal-to-noise ratio and high sensitivity have always been the goals and technical bottlenecks of detection, precision measurement and imaging. Quantum detection technology is one of the disruptive cutting-edge technologies in the world. Quantum information technology is introduced into the field of classical detection, hoping to solve the difficult technical bottleneck on the basis of classical physics. Compared with traditional detection methods, quantum detection has higher sensitivity, can receive weaker signals, requires lower transmission power, and has stronger anti-interference ability. In terms of precision measurement, the characteristics of quantum mechanics are used to make the measurement accuracy break through the classical physical limit, and then improve the measurement accuracy of the detection system. But with the development of remote sensing technology and people demand for long distance detection, we completed in the early completed close quantum detection, combined with remote sensing technology, the quantum squeezed light into the receiving system, using quantum phase-free amplification technology, make up for the low efficiency of the detector, make its imaging results close to the ideal detector. We designed a set of quantum squeezing light preparation, emission /receiving system, quantum enhancement module, quantum imaging system, balance homodyne detection system, data processing system, central control system in one of the remote quantum infrared detector, effective detection distance up to 100 meters, at the same time achieve high resolution imaging, the same environment and classical laser imaging resolution increased by 1 to2 times. In March 2000, Professor Siwen Bi conducted the exploration and research on quantum remote sensing. At the beginning of 2001, Professor Siwen Bi first put forward the concept of quantum remote sensing at home and abroad. In the past 20 years, through three stages of basic theoretical scientific experiments and key technologies, we have overcome many difficulties in theoretical research scientific experiments and key technologies ,and achieved breakthrough progress and innovative results, which have laid a key foundation for the follow-up quantum laser radar quantum remote sensing products.

High signal to noise ratio and high resolution have been the goal of remote sensing. Since the classical electromagnetic wave is influenced by the diffraction limit and quantum noise limit, increasing the resolution has been close to the limit of remote sensing, In this situation, in 14 years, the author through quantum remote sensing based theory, scientific experiment and the key technology research of the three phases, before the end of December 2014 completed the study of quantum remote sensing principle prototype. Quantum remote sensing prototype is based on the theory of quantum optics, which takes manipulation, preparation and control in quantum optical field as the experimental method. Through the experiment, the results obtained are the coherent light detection imaging resolution 2-3 times. Based on a large number of experimental studies, we completed the key technology of quantum remote sensing principle prototype, scheme design and principle prototype system. Through the test, the technical indicators of the principle prototype meet the requirements, which provide technical foundation for quantum remote sensing engineering principle prototype.
