The primary challenge currently faced by bio-inspired polarized optical compasses lies in their poor environmental adaptability, resulting low heading angle accuracy under complex weather conditions, such as cloudy and overcast days well when obscured buildings. To enhance this paper first theoretically analyzes the impact of major atmospheric interference factors on polarization patterns. An analytical model is established to investigate influence multiple scattering patterns, simulation...
Polarization navigation has been an active research direction in fields due to its autonomy and robustness, especially global satellite system-denied environment. Most existing bionic polarization sensing schemes employed the linear polarizer as analyzer. However, quadrature error between two sets of mutually orthogonal polarizers is usually inevitable, which may cause sensor output distortion directly affect performance sensors. In this paper, inspired by special polarization-sensitive...
The polarization compass is an autonomous, long-endurance technique that intended for enhancing the environmental suitability of integrated navigation systems. Numerous research on based single Rayleigh scattering model. However, real atmosphere usually non-ideal and does not conform to ideal model would have a constant error in sky with certain partial cover. Compared single-scattering model, Hannay's multi-scattering equations provides better description pattern atmosphere. Thus, ellipse...
Recent interest in high-precision positioning stages with large travel ranges has sparked renewed attention to the development of voice coil motors (VCMs). Due their output force, VCMs can actuate more complicated flexure structures, eliminate rail friction, and improve speed. The VCM structure is both compact flexible; hence, it convenient design for a variety stage structures. Furthermore, combined other actuators are able achieve high precision. In this paper, we summarize principles...
The ceramic composites of Cu-doped La1−xCuxTiO3+δ (x=0.05, 0.15, 0.3, 0.5) were synthesized by conventional solid-state reaction. complex dielectric properties the investigated as a function temperature (77 K≤T≤320 K) and frequency (100 Hz≤f≤1 MHz) separately. In all composites, constants increase monotonously loss undulates with temperature. And it is clearly observed that extraordinarily high low-frequency constant (~104) appear at room in La0.5Cu0.5TiO3+δ, which ~100 times larger than...
Rationale: Precise diagnosis and effective therapy of the tumor microenvironment (TME) remains a challenge. Fluorescence tracers for monitoring primary tumors are currently reported; however, they face challenges in accurately delineating real-time during surgery, including interference from background insufficient accumulation imaging reagents at sites. Additionally, although natural product podophyllotoxin (PPT) had potent broad anti-tumor activity, poor target specificity high toxicity...
Atomic force microscopes are a key tool in nanotechnology that overcome the limitations of optical and provide imaging capabilities with nanoscale resolution. We have developed an atomic microscope uses inexpensive quartz tuning fork as micro cantilever. Because its ease operation open structure, it can be easily customized by students. Due to low costs, is possible every student course has access one setup, allowing all students obtain deep insights into understand principles microscopy.
Au ∕ Tb Mn O 3 ( TMO ) Y Ba 2 Cu 7 − x YBCO capacitors were fabricated on LaAlO3 (LAO) and SrTiO3 (STO) substrates under identical conditions. Dielectric properties measured in the temperature range from 20to350K. High dielectric constants single transition peaks found both films. The of film STO substrate larger than those LAO substrate; correspondingly, was higher that substrate. Although x-ray diffraction showed films had same epitaxial orientation, atom force microscopy revealed...
