Pedestal p-GaN/InGaN/n-GaN nanorods have been fabricated on n-type Si (111) substrates by properly reducing the growth temperature of p-GaN surface layer. Continuous layers were formed top region accelerated lateral growth, while keeping underlying nanostructures and physical properties InGaN n-GaN intact, making it feasible for large-scale vertical integration. Growth layer at 500 °C followed annealing 600–800 improved crystal structures overall electrical luminescence pedestal nanorods.
Land surface temperature (LST) is a key parameter and plays an important role in hydrology, ecology, environment, biogeochemistry. It difficult for the existing satellites to acquire global LST with spatial temporal consistency. The Moon-based Earth observation platform long life, large coverage can observe continuously Earth, obtain global-scale LST. At present, various approaches retrieving from passive microwave remote sensing data have been developed satellite small constant viewing...
For a camera with automatic gain control, two images high and low optical can be output at the same exposure time. Due to small value, most of target details are hidden in dark pixels for image, brightness saturation usually appears image luminance areas. To obtain essential information from dual images, generation method dynamic range based on was developed. The is composed five parts, including enhancement detail, establishment Laplacian pyramid, selection fusion operator, reconstruction...
For the scientific complementary metal-oxide-semiconductor detector with dual gain control function, two images can be output simultaneously at any exposure time. The low image has small pixel brightness value, and most of illumination regions are usually black pixel. However, high in may saturated overexposed. To obtain a detailed for different illumination, dynamic range fusion method base on grayscale was developed. First Laplacian pyramid established; then performed according to weight...
In the infrared detection of small targets, blind pixels greatly interfere with accuracy target. Therefore, way how to correctly detect and eliminate is great importance. this paper, an in-orbit real-time pixel method that combines time-domain noise imaging sensor characteristics non-uniform correction coefficients proposed. Firstly, according working condition remote sensing camera, data reference source under high low temperature circumstances acquired, which exceeds threshold are marked...
With the development of space technology, spacecraft are serving more and exploration missions. The cameras on become an important data source for monitoring motion status spacecraft, as well landing takeoff processes at extraterrestrial bodies. However, less sensitive to rapid changes in external light environment cannot quickly adapt rapidly changing scenes, resulting slightly poorer imaging quality default camera parameter settings. In order obtain a better on-star effect, automatic...
As a unique natural satellite of the Earth, Moon has always attracted much attention, and one subject interest is establishment an Earth observation platform on Moon. Compared with existing spaceborne airborne platforms, Moon-based would have advantage ability to obtain global large-scale data. At present, study observations in theory, so it necessary use simulation methods understand performance platform. In this study, method for imaging thermal infrared band developed process. The...
Increasing attention is being paid to the monitoring of global change, and remote sensing an important means for acquiring observation data. Due limitations orbital altitude, technological level, platform stability design life artificial satellites, spaceborne Earth platforms cannot quickly obtain The Moon-based (MEO) has unique advantages, including a wide range, short revisit period, large viewing angle spatial resolution; thus, it provides new method obtaining At present, MEO not yet...
Pre-flight radiometric calibration is critical to ensure that sensors can demonstrate they meet their design performance specification. However, following launch it this verified and in particular the accuracy validated or if necessary corrected. As Earth observation data becomes widely used increasingly important from each satellite sensor be relied upon short longer term any potential biases between removed. This post-launch calibration/validation thus recognized as a key activity by all...
