#Euro-Indo collaboration develops new photodetector Photodetectors that analyse scattered light in the ultraviolet (UV) range of the spectrum are used often in situations where the rapid detection of hazardous biological
The detector is used then to extract the optical fingerprint from the scattered light. A large number of photodetectors, with very narrow bandwidths, is necessary so as to simultaneously detect as many different substances as possible.

Instead some of the light from the laser scatters and the path length increases because of this multiple scattering#something scientists refer to as the aman effect. his scattered light is emitted then from the powder in a strong diffuse form that is visually similar to a bright LED light.

and far more stably via the interaction between the illuminating light and the vibrating chemical bonds in the diamond lattice structure which results in scattered light at a different colour.

By continuously observing the scattered light individual molecules are seen moving in and out of the tiny gaps between the mirrors.

Scattered light usually reduces the resolution of conventional optical microscopes. The UT-researchers however found a simple and efficient way to actively use scattered light to improve the resolution of images.
It is like the fog has cleared, according to the first author Hasan Yilmaz. The smallest detail a traditional optical microscope can reveal is about half the wavelength of green light
NEW METHOD Randomly scattered laser light appears as a finely grained speckle pattern as a result of interference of many scattered light paths.
The high resolution picture is taken using scattered light! The speckle illumination method is surface-specific and robust to environmental noise.

or two different objects, based on the intensity of scattered light. The scattered light is detected by a common photodiode,
and the signals are digitized, analyzed and used to calculate the positions of the samples. Crucially, the JILA team verified the stability of the technique by using the two lasers to make two separate, independent measurements of a single sample.

By detecting the wavefront of light emitted from the guide star they can determine an optimum phase pattern that allows scattered light moving along different paths to focus at the targeted location.

but they are nonlinear devices requiring filtering of the scattered light. BSIT on the other hand is a linear nonreciprocal mechanism.
