Description

The image is a graphical representation of a laser-interferometer, which is used to measure the distance between two points. The interferometer consists of a light source, a beam splitter, and a detector. The light source emits a laser beam, which is split into two beams by the beam splitter. The two beams are then reflected off a mirror and recombined by the beam splitter. The detector measures the intensity of the recombined light, which is proportional to the distance between the two points. The graph shows the distance between two points as a function of time. The distance is plotted on the x-axis, and the time is plotted on the y-axis. The graph is labeled with various points of interest, such as the laser-interferometer, the beam splitter, and the detector. The graph also includes a curve that represents the distance between the two points as a function of time.
