Solar spectral irradiance (SSI) is a key parameter to study the composition, temperature, and dynamics of the Sun over time. An accurate SSI model leads to a better understanding of solar activity.
Micro-LED display technology is considered to be the next generation display technology. However, its large-scale commercialization still faces the challenge of immature technology and high cost. One of the challenges is how to realize the full color of Micro-LED.
Space telescopes are developing toward deep space exploration and maneuver to change orbit, with increasing demands on imaging quality, however, they experience changing and complex thermal environments.
The spatial heterodyne spectrometer (SHS) is a modern type (i.e., without moving parts) of the spatial modulation Fourier transform spectrometer, which is widely used in trace components in the fields including mineralogical, chemical warfare agents, atmosphere and interstellar emission observation.
Active laser detection technique based on cat-eye effect has the advantages of long detection distance and high orientation precision. The reflected light intensity of the cat-eye system is 2–4 orders of magnitude higher than the general diffuse reflection intensity. Thus, laser active detection technology based on the cat-eye effect may realize accurate aiming and directional confrontation. However, few studies focus on the influence of a multi-band laser with a large incident angle on the echo distribution.
Lead halide perovskite nanocrystals have established the special consideration of scholars in the last few years due to their cutting-edge nonlinear optical properties and progress in unpretentious synthetic procedures. These materials have efficient applications in various optoelectronic devices. Th enhancement of nonlinear optical properties of the perovskites can be influenced by doping of transition metal ions.
