Problems solved by technology

Among them, the GPS system is widely used, and it is a global, continuous real-time, high-precision navigation method, but its navigation information is controlled by people, so the signal is easily interfered, attacked or even destroyed; the geomagnetic compass is simple in structure, small in size and light in weight, but Its accuracy is low; the inertial gyroscope is free from interference and has strong concealment, but there is a cumulative error in long-term use

Abstract

The invention discloses a biomimetic direction analyzer. The biomimetic direction analyzer comprises a direction information acquisition device and a data processing module. The direction information acquisition device is used for detecting skylight polarization characteristics and converting an optical signal into an electric signal. The data processing module receives the electric signal transmitted through the direction information acquisition device and computes and processes the electric signal so that direction information is acquired. In the biomimetic direction analyzer, all nano-gratings and photosensitive pixel arrays which are located below the nano-gratings and are corresponding to the nano-gratings form a polarization-sensitive unit and the polarization-sensitive unit realizes incident skylight polarized detection and photoelectric conversion. Through use of a stable distribution way of a sky visible light polarization state in air, the direction information acquisition device and the data processing module, direction information is deduced and calculated.

Description

technical field [0001] The invention relates to the field of direction analysis devices, in particular to a bionic direction analyzer. Background technique [0002] Biologists have discovered that after billions of years of evolution, a variety of insects have evolved the ability to perceive the polarization of sky light and use it for navigation, which can help them complete behaviors such as foraging and homing. Biomorphological experiments have shown that some special ommatidia in the dorsal rim area (DRA) of the compound eyes of insects with polarization navigation ability are very sensitive to polarized light. These special ommatidia are arranged regularly, and the spatial arrangement of the microvilli in the nerve sensory rods has certain characteristics. It is these special ommatidia that sense the polarization properties of sky light and use it for navigation. [0003] The current direction analysis system mainly includes GPS, geomagnetic compass, inertial gyroscop...
