A nanoprobe is an optical device developed by tapering an optical fiber to a tip measuring 100 nm = 1000 angstroms wide. Nanoprobes can be used in bioimaging to provide improved contrast and spatial resolution of cells and tissues. [1] Types of nanoprobes used for bioimaging include fluorescence, chemiluminescence, and photoacoustic imaging. [1]
The principle of operation is based on the temperature dependence of the bandgap of GaAs. The GaAs crystal fixed on the tip of the fibre will be transparent at a wavelength above 850 nm. The position of the band edge is temperature-dependent and is shifted about 0.4 nm/K. The light is directed via the optical fibre to the crystal, where it is ...
LiDAR system emits pulsed and continuous-wave lasers to acquire 3-D information. The laser scanner is the main component of LiDAR. Lasers with a wavelength of 550-600 nm are used on a ground-based system (handheld laser scanning and terrestrial laser scanning), whereas airborne systems use lasers with 1000-1600 nm wavelength.

According to the New York Times, here's exactly how to play Strands: Find theme words to fill the board. Theme words stay highlighted in blue when found.
The caesium-antimony photocathode had a dramatically improved quantum efficiency of 12% at 400 nm, and was used in the first commercially successful photomultipliers manufactured by RCA (i.e., the 931-type) both as a photocathode and as a secondary-emitting material for the dynodes. Different photocathodes provided differing spectral responses.
Seth Trimble scored 19 points and No. North Carolina held off upset-minded Georgia Tech for a 68-65 victory in the ACC opener for both teams Saturday. Trimble was 5 for 6 from the field and 8 for ...
