Remote sensing is an advanced technology to explore the space and acquire earth-space information, with its accurate, comprehensive and dynamic detection and observation ability, RS plays an key role in earth observation, national defense, aerospace and deep space exploration. The advancement of science and urgent demands in economy and other fields put forward higher requirements for RS. Firstly, some important theoretical issues need to be addressed, such as RS information theory, spectral imaging mechanism, electromagnetic radiation transmission model. Secondly, the resolution power of RS instruments and their ability to utilize information needs to be improved. Finally, more detailed and richer RS information is needed during application. Of all these requirements, higher resolution, spectrum resolution, time resolution and further applications of RS are extremely important. While quantum remote sensing (QRS) performs very well in these aspects. QRS study was began in March, 2000, the concept was proposed in early 2001, then QRS technology researches began. The paper firstly introduces its background, concept and research status, its differences and advantages.

At first this paper summarizes the current situation and historical development of the spectrum research, the difficulties and demand background. Then it introduces the research status of quantum spectrum and research ideas of energy distribution in quantum spectrum. We explain the concept of quantum spectrum, the difference between quantum spectrum and spectrum. We elaborate energy distribution in quantum spectrum from three aspects, which are representation, feature and mechanism of quantum spectrum energy distribution. Finally we describe the application of monochrome quantum spectrum about imaging and detection aspects and give an overview of the quantum spectrum. Based on above research results we continue to study and achieve the detection of multi-spectral imaging, which provide the technical basis for the application. We try access to an advanced stage of quantum spectrum study as soon as possible.
Since the author conducted researches on quantum remote sensing (QRS) in March 2000 and on quantum spectral imaging and quantum detection in June 2003, some difficulties occur. What’s the basic theory and how to realize the technical application of QRS passive imaging? What’s the basic theory of quantum spectral theory? How to apply quantum light field entanglement state during long-distance quantum detection into use? These question urged the author to research and reflect the basic theory of light quantum (photon) future technology. Therefore, in 2006, the author began to conduct relevant exploration, and proposed the key concept of lightstring theory. Besides, after referring to some theory in modern optics and physics, namely, the optical frequency comb and the string theory, he put forward to make light quantum concept concrete based on the nature of light in lightstring theory , and on which, he proposed the generation mechanism of string-light effect. The past ten years has witnessed some preliminary progress and there will be more discoveries and progress be made in the future. From the research requirements, the paper firstly elaborates the significance of light quantum future technology, as well as its research history and status with the emphasis on its progress. The main content includes the concept of lightstring, its research method and target. Finally, the future study plan is briefly introduced. The author tries to find a new way to study the light in nature, its generation mechanism and theoretical basis for its future technology.
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.
