Constant Power lenses, automatic apertures, parallel sample illumination with quantitative indication of convergence angle, size of illuminated area, and electron dose at specimen.
The TEM features a quad lens condenser system that independently controls electron beam intensity (spot size) and convergence angle.
As the convergence angle range of SF CORDIC is [0,[pi]/8], where [pi]/8 = 0392699 is represented as 16'b0001 1001 0010 0010, we only need deal with the 13 least significant bits of the angle.
The Barrow VOR/DME RWY 25 approach shows grid courses ("040[degrees] G") and a notice, "Grid courses are true polar courses and convergence angle factor shall not be applied.
In a conventional two-camera, 3D rig system, the convergence angle is changed by moving the lens and the entire camera.
In this mechanism, distance is computed by measuring the convergence angle formed by the lines-of-sight from ommatidia of the left and right eyes (Baldus 1926; Barros-Pita & Maldonado 1970; Wehner 1981; Bauer 1981, 1985; Kral 1999; Kral et al.

The MIT algorithm combines several measures of the environment, including lateral separation, longitudinal separation, other aircraft velocity, convergence angle, and other aircraft heading rate.
The effect of the SEMs finite depth of field was modeled by varying the convergence angle of the incident electron beam.
In this paper, these complications are avoided by discussing the SAR fundamentals in terms of the end-to-end convergence angle of the radiation transmitted to and received from the target, since this term determines the SAR focusing action, while rotational ISAR is discussed in terms of its phase excursion.
The key parameters that determine the shape of the secondary are its entrance diameter, the convergence angle of the light at the focus of the primary, and the refractive index of the material from which the secondary is fabricated.
17), reported that entrance pressure drop tends to be independent of convergence angle at high flow rates while at lower flow rates the pressure drop decreases with convergence angle.
