  • Phase ripple of spatial light modulators

    Phase ripple of spatial light modulators

    Phase ripple is quantified by measuring the variation in intensity of the 1st order diffracted spot as compared to the mean intensity while writing a blazed phase grating to the SLM. Modulators (SLMs) are uniquely designed for pure phase applications and incorporate analog data addressing with high refresh rates (1400 Hz). The 1024 x 1024 SLM is good for applications requiring high speed. Rapid and programmable shaping of light fields is central to modern microscopy [1–3], display technologies, optical communications and sensing [4–6], quantum engineering [7–14], and quan-tum information processing [15–24].

  • The function of the small busbar in the closing power supply

    The function of the small busbar in the closing power supply

    The bus bar system within the panel is the conductive structure responsible for routing and distributing this incoming power to all connected circuits. It acts as the backbone of the electrical system, allowing current to be safely and efficiently divided among the protective devices. The panel's primary function is safety, using circuit breakers to automatically interrupt the flow of electricity when a fault or overload condition is detected. Designing a substation involves not only the visible equipment and ratings but also the less apparent factors—operational. In Simple words, a bus-bar is a common connection point or a node for multiple incoming and outgoing circuits such as power lines or feeders.
