Technical field: The utility model belongs to the technical field of photoelectric detection, and relates to an improvement of the optical dynamic target of the photoelectric theodolite dynamic precision detection equipment.

Background technology: With the rapid development of missile guidance technology and sensing technology, new requirements are constantly put forward for the measurement accuracy of shooting range tracking and measurement equipment. On the one hand, the measurement accuracy is getting higher and higher. For different target characteristics, various sensor measurement technologies such as visible and infrared are used. Therefore, the infield detection is required to adapt to the needs of various sensor measurement technologies, and to perform high-precision detection on several sensors working in different spectral bands at the same time. At present, the target used in China is shown in Figure 1, which is the supporting equipment for the infield detection of theodolite TV measurement accuracy, that is, the optical dynamic target. A light pipe 1 and a reflector 4 are arranged at both ends of its rotating arm 5, and the parallel light beam emitted by the light pipe 1, after being reflected by the reflector 4, represents the light beam from an infinitely distant target. The optical dynamic target is driven by the motor 3, and the rotating arm 5 rotates around the rotary axis 2, so that the trajectory enveloped by the outgoing light beam of the mirror 4 is a light cone, and the outgoing light beam is the generatrix of the light cone. Use this light beam to guide the theodolite 6 for tracking Measurement. Changing the rotation speed of the motor 3 can realize the requirements of different speeds and accelerations. The half cone angle α of the light cone is usually above 15 degrees. Since the light pipe is fixed on the rotating arm, it is difficult to expand other light sources, and there is a problem that multiple light sources cannot be used to measure multi-band sensors at the same time. This is one of the problems that have plagued scientific research workers in recent years.

Summary of the invention: In order to solve the problem that multiple light sources cannot measure multi-band sensors at the same time, the utility model adopts the technology of separating the light source from the rotating body as shown in Figure 2, which consists of a light pipe 1, a dichroic mirror 2, and several dichroic mirrors 3 , rotary shaft 4, several light pipes 5, reflector 6, reflector 7, reflector 8, pivoting arm 9, motor 10, workbench 11, gear 12, encoder 13, counterweight 14 composition. Light pipe 1, dichroic mirror 2, several dichroic mirrors 3, several light pipes 5, reflector 6 are fixedly installed on workbench 11, and dichroic mirror 2 is placed in front of the light hole of light pipe 1. Several dichroic mirrors 3 are placed between the dichroic mirror 2 and the reflector 6, and the reflector 6 and the several dichroic mirrors 3 are respectively placed in front of the light holes of several light pipes 5 placed side by side. 2. The optical axes of several dichroic mirrors 3 and reflective mirrors 6 combined light beams coincide with the axis of the rotary shaft 4. Dichroic mirrors 2 and reflective mirrors 7 are respectively arranged on the sides of the rotary shaft 4. The reflective mirrors 7 are fixed on In the middle part of the rotating arm 9, the center of the reflective surface of the reflector 7 coincides with the axis of the rotating shaft 4, an encoder 13 is housed on the rotating shaft 4, the reflecting mirror 8 is fixedly connected with one end of the rotating arm 9, and the other end of the rotating arm 9 is placed There are 14 counterweights.

Working process of the present utility model: when light pipe 1 and several light pipes 5 work, dichroic mirror 2, several dichroic mirrors 3 and reflector 6 receive light beams from light pipe 1 and several light pipes 5, adjust respectively Dichroic mirror 2, several dichroic mirrors 3 and reflecting mirror 6 make their light beams synthesize and coincide with the center of rotation axis 4, make reflecting mirror 7, reflecting mirror 8 receive combined light beam and reflect to form reflected light beam, then the utility model The television tracking dynamic target guides theodolite 15 to work.

The utility model adopts a combination method of different light pipes: when the theodolite requires multi-band sensors to work at the same time, the light pipes can be combined in various ways, which solves the problem that multiple light sources cannot be used to measure multi-band sensors at the same time. The utility model can be used for a single sensor It can also be used for the measurement of multiple sensors such as visible and infrared.
