Review of Geostationary Interferometric Infrared Sounder

To measure the global atmospheric three-dimensional distribution and change of temperature and humidity is one of the key areas in atmospheric remote sensing detection; it is also a new research and development direction in the field of meteorological satellite application. As a main element of China second generation of geostationary meteorological satellite Fengyun 4 (FY-4), which was launched o...
Pulse shape of ultrashort intense laser reflected from a plasma mirror

The temporal profiles of high-power short-pulse lasers reflected from self-induced plasma mirrors (PMs) were measured with high temporal resolution in the sub-picosecond window. The leading front shape of the laser pulse is found to depend sensitively on the laser fluence on the PM surface. Spectral modulation plays a key role in pulse profile shaping. Our findings will extend our knowledge on pro...
Design of double-zone aspheric diffractive intraocular lens with extended depth of focus

Heterogeneously integrating III-V materials on silicon photonic integrated circuits has emerged as a promising approach to make advanced laser sources for optical communication and sensing applications. Tunable semiconductor lasers operating in the 2–2.5 μm range are of great interest for industrial and medical applications since many gases (e.g., CO2, CO, CH4) and biomolecules (such as blood gluc...
Experimental demonstration of underwater optical wireless power transfer using a laser diode

We experimentally demonstrate an underwater optical wireless power transfer (OWPT) using a laser diode (LD) as a power transmitter. We investigate the characteristics of a solar cell and a photodiode (PD) as a power receiver. We optimize the LD, the PD, and the solar cell to achieve the maximum transfer efficiency. The maximum transfer efficiency of the back-to-back OWPT is measured as 4.3% with t...

Asa main instrument onboard geostationary meteorological satellite FY-4, geostationaryinterferometric infrared sounder (GIIRS) is used to measure the infraredspectrum of the earth atmosphere. The spectrum is inverted by meteorolo...
COL Cover Story: Pulse shape of ultrashort intense laser reflected from a plasma mirror [10/10/2018]

The interaction of ultrashort intense laser with plasma could produce energetic particles (electrons, positrons, neutrons and ions) and ultrafast radiation sources from microwave to γ-ray. These novel secondary sources have prom...
COL Cover Story: Design of double-zone aspheric diffractive intraocular lens with extended depth of focus [13/09/2018]

The accommodation amplitude of the human eye usually decreases to less than 1 D after 50 years old, resulting in the inability of eyes to focus near object accurately. This dysfunction is called presbyopia, which makes it impossible ...
