To support automatic focus, the sensor is designed to maintain a designated setting even when the incidence angle changes, enabling users to take both close-ups and far away shots with user friendly features that are found on digital cameras.
A rotatable sample holder made from a piece of aluminium plate and a graduated dial enabled beam-beam transmittance measurements over a wide range of incidence angle.
An incidence angle of -30[degrees] was chosen as a compromise between the loss of contrast (at lower angles of incidence) and the loss of light from the bottom of the scratch (at higher angles of incidence).
scan using a fixed incidence angle just below the critical angle (GIXRD) measurements reflectometric (XRR) and X-ray scattering niskokatowego (SAXS) for single crystals and thin epitaxial layers ultacienkich and complex heterostructures and superlattices.
The studies show that the reflectivity of a surface is at its minimum when the incidence angle of the laser beam to the metal surface is close to 90[degrees].
However, IAC also depends on solar incidence angle, especially for shades having non-uniform geometry (e.
However, the 3D aileron simulations called for a more powerful system with three-core processor and 4 GB of RAM, in order to produce a result in an adequate period of time for each incidence angle considered.
Therefore, the magnitude of absorption depends on the incidence angle ([Beta]) and the extinction coefficient ([Lambda]).
NA is given by the formula NA = n x sin (theta), where n is the refractive index of the medium through which the exposure light passes, and (theta) the maximum incidence angle formed by the exposure light.
Smaller transistors utilize design features such as ultra-shallow junctions, pocket and halo implants, and these transistors are also significantly more sensitive to beam incidence angle.
This factor accounted for the effect of folding and the variation of incidence angle.
The measurements for experiment A, with all wind turbine models operating simultaneously, showed that at the incidence angle [theta] = [0.
