Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
1[mass noun] Deflection of radiation or particles through an angle of 180°.
- ‘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.’
- ‘Clear sky forcing is the direct backscatter of solar radiation in clear skies.’
- ‘This inversion technique takes into account atmospheric effects on the radiation and spatial variations in the surface emissivity and backscatter.’
- ‘They exhibit very low backscatter and absorption.’
- ‘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.’
- 1.1Radiation or particles that have been deflected in this way.
- ‘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.’
- ‘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.’
- ‘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.’
- ‘However, gel-independent backscatter would be the same for all positions of the probe relative to the gel.’
- ‘Ultrasonic backscatter does react to changes in structure, however it can not be linked to a determined hardness value using the indentation method.’
Light from a flashgun or other light source that is deflected directly into a lens.‘backscatter causes an underexposed picture with a blizzard effect’
- ‘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.’
- ‘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.’
- ‘The holy grail of acoustic swath mapping is to use backscatter more quantitatively; that is, to transform the image into estimates of seafloor properties.’
- ‘Thanks, that is interesting, I had thought that the flash backscatter was the worst aspect.’
- ‘Our one of a kind accessory kit provides an affordable solution for close-up shots and flash ‘backscatter’.’
Deflect (radiation or particles) through an angle of 180°‘the temperature of an optical fibre subtly affects how much light is backscattered’‘backscattered sound reaches the sonar receiver’

- ‘Incident solar energy is backscattered away from the earth and acts as a natural cooling mechanism for this area.’
- ‘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.’
- ‘Lidar uses a pulsating laser source and signals backscattered by molecules and particles are analysed using a specially designed telescope.’
- ‘Monazites were identified in thin section by their very bright backscattered electron images and verified by energy-dispersive spectrometry.’
