In the study of quantum remote sensing, quantum spectral imaging. Since the beginning of 2001, after three stages of basic theory, scientific experiment and key technology research, has made breakthrough progress and innovative results. With the deepening of the research work and needs, some basic theoretical issues and cutting-edge technical problems need to be explored and studied. This paper discusses wave-particle duality of light is one of the important content. In more than and 100 years, wave-particle duality of light as research has made important progress. But the wave-particle duality of light is like what? Wave-particle duality of light like mechanism is what? Has been the most intense debate on the issue of Optics and physicists. In this paper, the author firstly summarizes the wave-particle duality of light development history and present situation of the research study, describes the research ideas of wave-particle duality of light; on this basis, the author puts forward the application of lightstring concept focuses on the wave-particle duality of light phenomenological characteristic geometry shape and movement of the content; describes the wave-particle duality of light like generated string-light effect mechanism. To study the wave-particle duality of light like two, a profound understanding of wave-particle duality of light nature, put forward a new research method.

Abstract Scientific terms and concepts sometimes evolve so that their semantic meanings are changing, to better serve the purposes of their use in scientific practices. Acknowledging the importance of such a process provides a viewpoint on the role of wave-particle duality (WPD) in modern quantum optics and how it is connected to its historical role. The transformation of WPD into a quantitative and operationalised concept is approached here from the viewpoint of the role of WPD as a linguistic practice based on natural language in communicating about experiments and their results and designs. The perspective adopted is based on semantic change and variation of WPD as driven by its role as natural language expression in pursuing the epistemic and the pragmatic goals of the inquiry. This provides a perspective that connects the historical and contemporary roles of WPD through its pragmatic linguistic role. This perspective shifts the focus from philosophical realism-driven questions about WPD as related to the nature or behaviour of photons to questions of how that concept is used in practices of quantum optics research, for what purposes, and with what benefits.
