【摘要】：大长度测量仪检定工作一般在野外基线场上进行,耗时费力、强度高效率低、受环境影响严重等问题一直困扰计量检定人员。为改变这一落后作业模式,在手持激光测距仪室内检定装置研制成功的基础上,该文提出基于折光腔法与虚拟基线理论构造鉴相式大长度测量仪检定装置,拟将野外检定基线场完整搬入室内。利用费马原理设计的折光腔将长度1 000 m的光路压缩在数十米以内,利用光的反射定律推导出虚拟基线(室内大长度各段标准值)的计算方法,同时进一步提出检定装置的结构设计,技术参数及控制措施,并通过对系统潜在影响因素分析以论证该大长度室内检定装置的可行性。
[Abstract]:The verification work of large length measuring instrument is generally carried out in the field of baseline, which is time-consuming and laborious, high intensity and low efficiency, and seriously affected by the environment, etc. In order to change this backward operation mode, the metrology and verification personnel have been perplexed all the time. On the basis of the successful development of indoor verification device for hand-held laser rangefinder, this paper presents a phase discriminant large length measuring device based on refraction cavity method and virtual baseline theory. The field verification baseline field will be completely moved into the room. The refractive cavity designed by Fermat principle will compress the optical path of 1 000 m in length to less than 10 meters. Based on the reflection law of light, the calculation method of virtual baseline (the standard value of large indoor length) is deduced. At the same time, the structure design, technical parameters and control measures of the verification device are put forward. The feasibility of the large-length indoor verification device is demonstrated by analyzing the potential influencing factors of the system.
