General view of the device


Optical unit of the device.


The device is designed for the measurements of front to back scattering coefficient of coats and reflecting details in a wide range of light angles.

 Possible applications:

  • Measurements of reflectivity of paint coats, reflecting materials, road paints. Back scattering coefficient can be measured at various light angles with an accuracy better than 5%.

  • To measure size and reflectivity of glass spheres used in reflecting paint coats or abrasives. Spheres sizes: 40 - 1000 microns. Size measurements accuracy 1 - 10 %. Reflectivity measurements accuracy 5%.

 Measurement methods: 

  • Measurement and analysis of scattered light indicatrix.

  • Measurement of a single particle back scattering.

Development status:

Prototypes of the diagnostic devices have been designed, manufactured and tested.

Collaboration offers:

Joint patenting, development and manufacturing.

 Competitive advantages.

There is no devices measuring back scattering of a single particle. Small sized prototype is available.
