[0021] Example 1
[0022] A photoelectric composite test sensor. The sensor is composed of an electric probe and a laser speed probe. The electric probe is composed of a conductive wire and a polymer film. The conductive wire is uniformly cured in two layers by an adhesive. Between the hot-melt polymer adhesive films, the number of conductive filaments is evenly distributed on the circumference ≥ 2, and the conductive filaments are exposed outside the polymer adhesive film, and the outer surface of the conductive filaments is coated with insulating paint. The electric probe is evenly coated on the surface of the laser speed measuring probe. The laser speed measuring probe includes an optical fiber probe and a speed measuring fiber. The optical fiber probe is arranged on the top of the speed measuring fiber, and the end surface of the electric probe is higher than the optical fiber. On the end face of the probe, the tail of the speed measuring fiber is connected with the optical m...

[0023] Example 2
[0024] A method for preparing a photoelectric composite test sensor. The sensor includes two parts: an electric probe (conductive wire, polymer film) and a laser speed probe (optical probe, speed measuring fiber), such as figure 1 Shown. In the process of sensor production, use special tooling and fixtures to evenly distribute conductive wires (number ≥2 to ensure reliability) through adhesives and cure them between two layers of hot-melt polymer film. The cured electrical The probe has the characteristics of high electrical insulation, corrosion resistance, and good thermal stability. Subsequently, with the special reel and shaping process, the polymer film containing the conductive wire is evenly coated on the surface of the optical fiber probe, and the outer surface of the conductive wire exposed outside the polymer film is coated with insulating paint. In order to avoid the influence of the optical fiber probe on the electrical probe test, make sure that t...

[0025] Example 3
[0026] Taking the application of the photoelectric composite test sensor in the detonation loading experiment of the metal flyer as an example, the method of use is further explained.
[0027] Such as figure 2 As shown, the experimental device is composed of a detonator, a booster column, a plane wave lens, an explosive, and a metal flying piece. At a certain distance from the metal flying piece, the photoelectric composite test probe is fixed with a bracket and the probe is facing the metal flying piece. The speed measuring fiber and electric probe lead of the composite probe are respectively connected to the optical measuring system and the electric measuring system. In the detonation experiment, a detonator was used to detonate the plane wave lens, which was transmitted to the cylindrical explosive synchronously, generating a plane detonation wave, and driving the metal flying piece to the composite probe. When the detonator detonates, both the electrical m...
