    Abstract: The general approach to finding the form factor of a compound particle and a system of particles in the Ray-leigh-Gans-Debye (RGD) approximation is considered. The rotational-translational properties of light scattering amplitude in the RGD approximation are formulated. Using such properties, the analytical expressions for the amplitude of light sc...

    Abstract: New relationships of displacement signal using four and only two opposite sectors on quadrant photodiode are derived. Sensitivity of position sensitive devices with quadrant photodiode is analyzed. The sensitivity is bigger for (1+1) than (2+2) configuration, for equal parameters. This is an important parameter in designing of command and control d... Show More
