  2. Zeta Reticuli - Wikipedia

    en.wikipedia.org/wiki/Zeta_Reticuli

    Zeta Reticuli, Latinized from ζ Reticuli, is a wide binary star system in the southern constellation of Reticulum.From the southern hemisphere the pair can be seen with the naked eye as a double star in very dark skies.

    en.wikipedia.org/wiki/Reticulum

    Reticulum is a small, faint constellation in the southern sky.Its name is Latin for a small net, or reticle—a net of crosshairs at the focus of a telescope eyepiece that is used to measure star positions. [2]

  5. Z-pinch - Wikipedia

    en.wikipedia.org/wiki/Z-pinch

    In fusion power research, the Z-pinch (zeta pinch) is a type of plasma confinement system that uses an electric current in the plasma to generate a magnetic field that compresses it (see pinch). These systems were originally referred to simply as pinch or Bennett pinch (after Willard Harrison Bennett ), but the introduction of the θ-pinch ...

  6. Z-scan technique - Wikipedia

    en.wikipedia.org/wiki/Z-scan_technique

    In nonlinear optics z-scan technique is used to measure the non-linear index n 2 (Kerr nonlinearity) and the non-linear absorption coefficient Δα via the "closed" and "open" methods, respectively. As nonlinear absorption can affect the measurement of the non-linear index, the open method is typically used in conjunction with the closed method ...

  7. ZScreen - Wikipedia

    en.wikipedia.org/wiki/ZScreen

    ZScreen is a push-pull electro-optical liquid crystal modulator that is placed immediately in front of the projector lens or computer screen to alternately polarize the light from each video frame.

  8. Photomask - Wikipedia

    en.wikipedia.org/wiki/Photomask

    In semiconductor manufacturing, a mask is sometimes called a reticle. [1] [2] In photolithography, several masks are used in turn, each one reproducing a layer of the completed design, and together known as a mask set. A curvilinear photomask has patterns with curves, which is a departure from conventional photomasks which only have patterns ...

  9. Argument (complex analysis) - Wikipedia

    en.wikipedia.org/wiki/Argument_(complex_analysis)

    Figure 1. This Argand diagram represents the complex number lying on a plane.For each point on the plane, arg is the function which returns the angle . In mathematics (particularly in complex analysis), the argument of a complex number z, denoted arg(z), is the angle between the positive real axis and the line joining the origin and z, represented as a point in the complex plane, shown as in ...
