WebJun 1, 2024 · Any lateral misalignment can be expressed in terms of lateral shift along the x-axis and the y-axis, which are the mutually perpendicular horizontal and vertical axes, both being perpendicular to the optical axis. Any misalignment along the x-axis and the y-axis manifests as a drop in intensity along the respective axes. WebDirect sunlight absorption by trace gases can be used to quantify them and investigate atmospheric chemistry.
