... to the deteriorating heliostats optical performance, balancing the deviations and preventing the degradation. The enhanced aiming strategy took into account heliostat aberrations to aim for strategy optimization after adopting the indicated parameters. As seen in Fig. 5.16(b) , the resulting flux distribution had...

.... The work reported in ( Roy et al., 2018 ) demonstrates flat metasurface lens on a steerable mirror which can correct aberrations. Contact profilometry and atomic force microscopy using optical readout are popular in micro- and nano-imaging. The profiler probe tip is attached to a cantilever...

... and Santos (2014a , 2004b) describe modifications to optics equipment that can be made to support visually impaired students. Specifically, the authors describe how ray tracing diagrams can be created via magnets representing the ray, optical axis, object, and image, and a magnetic board to support...

... in the next presentations. For example, what is Popper's attitude to verisimilitude? ²⁵ In an introductory calculus-based course on optics and modern physics, the changing historical attitudes toward the nature of light were explored. Various developments connected with light are presented...

... introduced by optical aberrations ( Dickinson et al., 2018 ). In the case of MoS₂ flakes fabricated by chemical vapor deposition methods, the morphological difference between Mo-zigzag and S-zigzag triangles was used to identify the crystal orientation using optical images ( Van Der Zande...

..., sample, and detector to be precisely moved with respect to each other. The various x-ray optics that we will look at later in this chapter are also mounted at set positions on the goniometer upon two arms, defining the incident side (from source to specimen, often called θ for historical reasons...

... were Wunderjahren, with discoveries in both optics and gravitation, and steps toward the invention of calculus. Returning to Cambridge in 1667, he was elected a Fellow of Trinity College, a position limited to only a few, and one of great prestige. In 1669, he became a Lucasian Professor of Mathematics...

... trickier and difficult to analyze for complex systems such as microscopes and telescopes. Complex systems employ several optical elements that need to be considered and corresponding aberrations may need to be incorporated. In addition, a situation may arise when one of the optical elements in a complex...

..., it distorts and blurs the outer parts of images. This spherical aberration could be mitigated by an aperture stop to block marginal rays at the edge of the imaging lens. To enlarge the field of view and improve the spatial resolution, one needs to design the curvatures of interfaces among optical elements...
