In this work, injector tests were performed under various working conditions using a schlieren diagnostic system. Additionally, the parameter dependence of beam characteristics was investigated to optimize the supersonic molecular beam’s (SMB) characteristics and improve its fueling performance. The results show that the length of the zone of silence and the divergence angle of the beam is affected by system conditions and injector characteristic parameters. Besides, this paper provides the quantitative change law of the beam characteristic parameters. Furthermore, comparisons between the ordinary round-hole injector and the self-developed integrated injector reveal that the self-developed integrated injector outperforms the ordinary round-hole injector in terms of effective beam injection distance and beam aggregation performance. Therefore, this study creates a database and a reference for supersonic molecular beam injector design and beam optimization on various devices.","PeriodicalId":37925,"journal":{"name":"Zhongguo Kexue Jishu Kexue/Scientia Sinica Technologica","volume":"72 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134951133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The three-wavelength array beam illumination combined with Fresnel prism cone scanning mode is used to realize the rapid multiwavelength three-dimensional imaging of the airborne platform. This study introduces the details of a three-wavelength laser light source module, Fresnel prism beam scanning module, multiwavelength coaxial transceiver optical system, and linear and single-photon composite detection, acquisition, data processing, and so on, based on the system’s operating concept. The multiwavelength laser common aperture transceiver, synchronous acquisition, processing, and storage assure the integrity and consistency of spectral and spatial geometric data in space and time and then provide data support for multiwavelength data fusion and land-water integrated detection. To test and assess the performance of an airborne three-wavelength LiDAR, a system static test was performed first, followed by a static ranging test on a 3.6 km target was completed. The ground dynamic test was then performed, and the system’s software and hardware were tested. The imaging data were basically consistent with that of commercial LiDAR. Finally, the airborne flight test was performed, and the three-wavelength 3D imaging was completed in cities, industrial areas, hills, reservoirs, and other areas. The land-water integrated detection and the fusion of three-wavelength linear and single-photon data in spectral and spatial dimensions are preliminarily realized.","PeriodicalId":37925,"journal":{"name":"Zhongguo Kexue Jishu Kexue/Scientia Sinica Technologica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44054916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
