«The high detection efficiency and low dark count rate of the SNSPD means that the weak signal from the backscattered light can be detected with a high signal - to - noise ratio,» said Xia.
In nano - FTIR, a sharp metalized tip is illuminated with a broadband infrared laser beam, and the backscattered light is analyzed with a specially designed Fourier transform spectrometer.
As the temperature changes down the length of the borehole, the light travels at slightly different speeds, and the color of the backscattered light changes slightly as well.
The frequencies of the backscattered light are measured by an optical receiver and those signals are processed to determine temperatures.
To measure temperatures along the cable's length, the team sends pulses of light down the fiber and observes how the fiber backscatters the light, returning it in the direction from which it came.

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.
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 glider used optical and acoustic backscatter — techniques similar to radar in which sound or light is bounced off of surroundings and analyzed upon return — to survey the water for sediment particles of two different sizes (0.4 and 0.1 millimeter) commonly used in models.
