The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Furthermore, the terms "first," "second," and the like are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.
It should also be noted that, unless expressly stated or limited otherwise, the terms "disposed" and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
The application of the panoramic beam comprises the aspects of panoramic laser fuze detection, photoelectric slip rings and the like. For the detection of the laser fuse in the panoramic view, the common beam layout mode mainly comprises a multi-radiation scheme, a partition scanning scheme and a synchronous scanning scheme, wherein the optical axis of the beam emitted by each scheme can be vertical to the elastic axis or form a certain included angle, so that a disc-shaped or conical beam detection field is formed.
For example, in a multi-radiation scheme, the number of receivers and the number of lasers are equal, the fields of view are matched, the emission windows and the reception windows are uniformly distributed around the projectile body, a plurality of radial narrow light beams jointly form a detection field, and the emission light beams and the reception fields of view have strong directionality. The mode has low requirement on the transmitting power of the laser, so that the mode is more applied to small air-to-air missiles.
The zoning scheme is composed of several fan-shaped beams to form a detection field, and the number of the receivers is equal to that of the lasers and the field of view is matched. Compared with the multi-radiation scheme, the partition scheme has higher requirements on the average power of the laser, and the detectable minimum target size is smaller.
The subarea scanning scheme is in a subarea view field, only the laser scans to form a detection field, and the detectors receive the detection field in subareas, so that all power emitted by the laser can be effectively utilized, and the acting distance is enlarged.
The transmitting and receiving system of the synchronous scanning scheme synchronously scans, detects and receives. The synchronous scanning scheme concentrates the full power of the laser into a narrow beam, reducing background noise due to reduced receive field of view. The key point of synchronous scanning is that a receiving field and a transmitting field are required to be matched synchronously, the structure is complex, a special high-speed rotating scanning system and a small-sized high-power laser are required to be manufactured, a longer acting distance and a higher distance resolution can be realized, and the laser collision avoidance warning device is more applied to a no-load laser radar, such as a helicopter laser collision avoidance warning device.
When the photoelectric slip ring is applied, the electrical connection of the rotating end and the fixed end of the photoelectric slip ring, such as power supply and signals, is transmitted through the conductive slip ring. However, long-term friction between the conductive slip ring contact and the ring body can cause performance degradation, low reliability and poor anti-electromagnetic interference capability. Therefore, optical fiber slip rings are also often used instead of conductive slip rings. The optical fiber slip ring is formed by additionally arranging an optical fiber rotary connector in a traditional conductive slip ring and flexibly connecting through a mechanical plugging mechanism, an optical fiber collimator, a DOVE prism, a miniature precision shaft system and a mechanical connecting and adjusting mechanism are selected in the optical fiber slip ring, and the optical fiber slip ring transmits signals through optical fibers, so that the optical fiber slip ring is high in confidentiality, small in electromagnetic interference and convenient for long-distance transmission; the generated dust is less, and the service life is long; the volume is small and the weight is light; the loss is small (<1.0dB), the rotation rate is high (1000rpm), but the manufacturing cost of the optical fiber slip ring is very high, the power supply capacity is not available, the energy transfer function of the conductive slip ring is still needed, and the shafting between the multi-channel optical fiber slip rings needs to ensure precise alignment, so that the reliability of information transmission is seriously influenced when the abrasion of gears for a long time influences the optical fiber transceiving alignment.
In order to solve the problem that a panoramic system integrating transceiving is not available in the prior art, the embodiment of the application provides a panoramic light detection device, which adopts an optical ring beam mode to realize transceiving different apertures and channel separation integration, can realize the panoramic light beam application integrating transceiving, and provides an application scheme integrating non-contact slip ring transceiving and panoramic laser radar detection transceiving.
