«The detection of landmines by neutron backscattering: Exploring the limits of the technique.»

The frequencies of the backscattered light are measured by an optical receiver and those signals are processed to determine temperatures.

The process is monitored by means of, for example, electron backscatter diffraction (EBSD); a technique that makes it possible to «reveal» the structure in the patterns.

For example, the sensor transmits its data to the handheld reader passively, by backscattering some of the incoming energy.

In the team's demonstrations, the total power consumption of the backscatter system was 11 microwatts, which could be easily supplied by a tiny coin - cell battery for a couple of years, or powered using tiny solar cells.

Although backscatter and millimeter wave scanners might have given screeners cause to be suspicious of an underwear bomb, neither are used in all airports, and passengers concerned about exposure to radiation can often opt to instead be frisked by security personnel.]

When this value was multiplied by the mean layer thickness and aggregation area estimated from the ADCP backscatter data, we estimated a total biomass of 2.0 million tons with krill comprising an estimated 88.4 % of the total acoustic backscatter.

A team at Disney Research is looking at harnessing a technique called ultra-wideband (UWB) ambient backscatter, which would allow IoT devices to save power and ditch their radio transmitters by piggybacking their communications on the multitude of FM and cellular signals already in the air.

[11] Because the COP seeps are characterized by large visible gas bubble plumes they can be detected and mapped by sonar backscatter.

You can prove this by looking at thick clouds about to rain — they're darker because increased droplet size means more direct backscattering, less light diffusely scattered.»

Whilst plausible, it's wrong because light transmission is controlled by two factors: «shielding» [enhanced backscattering until geometrical information is lost]; isotropic scattering.

Following major volcanic eruptions, it is necessary to avoid corruption of the backscattered signal caused by enhanced aerosols.

Satellite instruments provide global maps of surface UV irradiance by combining backscattered radiance measurements with radiative transfer models.

The model consists of two components whose refractive indices resemble those of detritus - minerallike and planktonlike particles, whose size distributions are constrained by underwater light linear polarization signatures, and whose mixing ratios change as a function of particulate backscattering efficiency.

The strength of the backscattered signal is determined by the strength of temperature inhomogeneities with size on the order of 10 centimeters (cm).

The ceilometer (CEIL) is a remote - sensing instrument that measures cloud height, vertical visibility, and potential backscatter signals by aerosols.

So Ira, if you really are sincere about wanting to know where the 33K difference comes from, you could start by calculating the Mie backscatter cross section of a 10um dielectric sphere, and I would suggest calculating it with a 9.25 um or 10.59 um em wave incident on it.
