Shearing type linear trace laser detection system

Abstract

The invention relates to a shearing type linear trace laser detection system. Instrument components of the shearing type linear trace laser detection system are arranged on a shock absorption table, so that a necessary stabilizing condition for precision measurement is guaranteed; due to the translation, the rotation and the lifting of a multifunctional objective table, quick adjustment and positioning on the space position of a supporting body on the objective table are realized; an electric control angle displacement table can implement that an inclination angle of one plane on the electric control angle displacement table within + / - 15 degrees in any direction can be adjusted; a microscope device is mainly used for amplifying a tiny trace on a section and transmitting the tiny trace to a computer for displaying; the feature of the tiny trace on the section is detected and extracted by controlling a high-precision laser displacement sensor and a precision electric sliding table. The invention provides the shearing type linear trace laser detection system; by the combination of a high-precision laser distance measurement technology and ingenious optical imaging, high-precision detection on the trace on the section is realized. The shearing type linear trace laser detection system is suitable for laser detection on a shearing type linear trace.

Description

technical field [0001] The invention relates to a laser detection system for shearing linear traces, which belongs to the technical field of police equipment innovation. Background technique [0002] With the rapid development of my country's high-speed railways, various cases of cutting and stealing communication cables and piercing ground wires along the railway lines are on the rise year by year. Such crimes pose a great hidden danger to the safety of high-speed railway transportation and are the key targets of railway public security agencies. The linear traces caused by shearing tools are the most common traces in the cases of piracy along the railway. They are not easily damaged, difficult to disguise, high in occurrence rate, and good in appraisal value. It is of great significance to confirm the suspect. For the comparison and inspection of linear traces, tool trace experts at home and abroad mostly use the microscope to observe the linear traces artificially to com...

Problems solved by technology

For the comparison and inspection of linear traces, tool trace experts at home and abroad mostly use the microscope to observe the linear traces artificially to compare the linear traces, so as to judge the degree of coincidence between the thick and continuous lines on the broken surface of the cable (mark bearing body). Huge workload and high subjectivity, often cannot be used as evidence in court
