At HEO, we deliver commercial on-demand, resolved non-Earth imaging (NEI) and analytic services at scale to government, defense, and commercial customers using a growing constellation of in-space sensors.
图1不是随手拍的,而是遥感的一个新领域——非对地成像(Non-Earth Imaging,简称NEI),什么是NEI?有什么用途? 图1 资源三号卫星在太空中的实景图像(引自HEO) 非对地成像(NEI)是指使用天基传感器拍摄太空物体获取高分辨率图像,拍摄的对象包括其它卫星、空间站、太空碎片或小行星等,NEI也称为卫星到卫星成像(Satellit...
The radiant energy concentrator can operate efficiently with only single axis tracking of the Sun in part because the reflective sides form orthogonal acceptance angles corresponding to the annual and daily apparent passage of the Sun on Earth....
Concentration of sunlight to solar-surface levels using non-imaging optics. Nature 339 (6221), 198-200.Gleckman P, O'Gallagher J, Winston R. Concentration of sunlight to solar- surface levels using non-imaging optics. Nature 1989;339:198-200....
Entanglement has a capacity to enhance imaging procedures, but this remains unexplored for attosecond imaging. Here, we elucidate that possibility, addressing orbital angular momentum (OAM) entanglement in ultrafast processes. In the correlated process non-sequential double ionization (NSDI) we demonstrate...
Coral reefs are some of the most productive ecosystems on earth (see Table 8.3). Threats to the function and structure of coral reef ecosystems have been associated with wastewater discharges to major rivers that ultimately drain into oceans, carrying nutrients and microbial populations. More recently...

Frozen soils cover about 40%of the land surface on the earth and are responsible for the global energy balances affecting the climate.Measurement of the thermal properties of frozen soils during phase transition is important for analyzing the thermal transport process.Due to the involvement of phase...

but the crucial non-invasive DBS capability has not been validated so far. We first focused on validating the locus of TI stimulation using computational modeling and cadaver measurements. We followed this by performing simultaneous TI and functional magnetic resonance imaging (fMRI) experiments designed...
