Definition of backscatter in English: backscatternounˈbakskatəˈbakˌskadər mass nounPhysics 1Deflection of radiation or particles through an angle of 180°. Example sentencesExamples - When backscatter is isotropic in the studied plane, the ratio of intensities of backscatter at any pair of angular positions of the detection axis of the probe will be unity.
- They exhibit very low backscatter and absorption.
- Clear sky forcing is the direct backscatter of solar radiation in clear skies.
- Different solutions have therefore been published: using the magnetic and magnetic-electrical characteristics of this layer, using the sound velocity of ultrasonic waves, and using the backscatter of ultra-sonic waves.
- This inversion technique takes into account atmospheric effects on the radiation and spatial variations in the surface emissivity and backscatter.
- 1.1 Radiation or particles that have been deflected through an angle of 180°.
Example sentencesExamples - However, gel-independent backscatter would be the same for all positions of the probe relative to the gel.
- Today satellites such as ESA's Envisat routinely scan the Earth with radar signals, building up highly detailed surface images - even through clouds and local darkness - out of reflected radar backscatter.
- Ultrasonic backscatter does react to changes in structure, however it can not be linked to a determined hardness value using the indentation method.
- A lens filter of appropriate laser wavelength may be used over the top of an endoscope viewing port to protect the eye from laser backscatter.
- Colors are derived from side scan backscatter data, with warmer colors (red and yellow) indicating high backscatter, and cooler colors (blue and purple) indicating low backscatter.
- 1.2Photography Light from a flashgun or other light source that is deflected directly into a lens.
backscatter causes an underexposed picture with a blizzard effect Example sentencesExamples - You will also be able to judge the water clarity - too much backscatter - forget the flash (if you're able to) and go to available light.
- Thanks, that is interesting, I had thought that the flash backscatter was the worst aspect.
- The holy grail of acoustic swath mapping is to use backscatter more quantitatively; that is, to transform the image into estimates of seafloor properties.
- Our one of a kind accessory kit provides an affordable solution for close-up shots and flash ‘backscatter’.
- The speed and flash/backscatter were sometimes issues, but just buy a fast 512MB card and shoot repeatedly, and you'll wonder why some spend so much more.

- Plan B would flood the stratosphere with billions of tiny metal-coated balloons, ‘optical chaff’ to backscatter the sun's rays.
- The sound is backscattered from the sea bed according to the topography, sediment type, and small-scale bottom roughness.
- Monazites were identified in thin section by their very bright backscattered electron images and verified by energy-dispersive spectrometry.
- Incident solar energy is backscattered away from the earth and acts as a natural cooling mechanism for this area.
