Dual-Comb Ranging Review

Zebin Zhu, Guanhao Wu

Engineering 2018, Volume 4, Issue 6,   Pages 772-778 doi: 10.1016/j.eng.2018.10.002

Abstract:

Absolute distance measurement is a fundamental technique in mobile and large-scale dimensional metrology. Dual-comb ranging is emerging as a powerful tool that exploits phase resolution and frequency accuracy for high-precision and fast-rate distance measurement. Using two coherent frequency combs, dual-comb ranging allows time and phase response to be measured rapidly. It breaks through the limitations related to the responsive bandwidth, ambiguity range, and dynamic measurement characteristics of conventional ranging tools. This review introduces dual-comb ranging and summarizes the key techniques for realizing this ranging tool. As optical frequency comb technology progresses, dualcomb ranging shows promise for various professional applications.

Strategic Study of CAE 2023, Volume 25, Issue 1,   Pages 142-154 doi: 10.15302/J-SSCAE-2023.07.001

Abstract:

Electronic detonators not only improve delay accuracy and the flexibility of initiation network design, but also realize the full lifecycle safety control of detonators from production to transportation, storage, and blasting operation. Therefore, electronic detonators are the key development direction of the civil explosive industry. This study summarized the development status of the electronic detonator initiation technology from the aspects of electronic detonators’ structure, application scenarios, intelligent level,blasting design theory, and failure mechanism. Our study indicates that electronic detonators will develop toward serialization and standardization, the electronic detonator initiation technology will develop toward more intelligence, the electronic detonator delay design theory will develop toward short delay, and the electronic detonator initiation network will develop toward a large scale. Based on engineering practices, we summarized the technological and application problems of electronic detonators, including frequent occurrence of misfire detonation, disconnection between detonation research and application, limited product types, and a defective standards system. Considering the demand of the civil explosive industry, we proposed the following key research directions: theories of precise delay-controlled blasting, integration of information technology with electronic detonator initiation, series of differentiated electronic detonator products, and standards systems of electronic detonators.

Keywords： electronic detonator     initiation technology     delay timing     design theory     standard system
