Shooting and triggering system for ultra-high-speed cameras in brittle materials research

Abstract

The invention discloses a shooting trigger system suitable for an ultra-high-speed camera in the research of brittle materials, including a conductive sheet a, a conductive sheet b, and an ultra-high-speed camera; the conductive sheet a and the conductive sheet b are connected with a copper-silver conductive coating, and the copper-silver conductive coating The conductive sheet a is connected to the central copper wire of the coaxial cable, the conductive sheet b is connected to the mesh conductive layer wire of the coaxial cable, the connection between the conductive sheet a and the central copper wire of the coaxial cable, and the conductive sheet b The connection with the mesh conductive layer wire of the coaxial cable is fixed with a staple to form two fracture trigger sensors; the ultra-high-speed camera is connected with two BNC connectors of the coaxial cable; the central copper wire of the coaxial cable and the mesh of the coaxial cable The conductive layer wires are respectively connected to two coaxial cable BNC connectors through coaxial cables. The shooting trigger system of the present invention solves the problem in the prior art that the shooting of an ultra-high-speed camera is triggered by artificial triggers and wires.

Description

technical field [0001] The invention belongs to the technical field of shooting trigger systems, and in particular relates to a shooting trigger system suitable for ultra-high-speed cameras in the research of brittle materials. Background technique [0002] As far as the prior art is concerned, ultra-high-speed cameras have the characteristics of fast shooting speed and short continuous shooting time. Taking the Kirana 01M ultra-high-speed camera as an example, its minimum shooting rate is 1,000 frames per second, and its maximum rate is 1 million frames per second. It can continuously shoot 180 photos at the highest and minimum shooting rates, and the time-consuming corresponds to 0.18 seconds, and 0.00018 seconds, at this speed, it is almost impossible to manually trigger the camera to capture the image of the moment of crack cracking, so it is necessary to develop a set of ultra-high-speed camera shooting trigger system suitable for the shooting rate of 1000 pictures per ...
