… employs a beam of modulated monochromatic light to carry information from transmitter to receiver. The light spectrum spans a tremendous range in the electromagnetic spectrum, extending from the region of 10 terahertz (104 gigahertz) to 1 million terahertz (109 gigahertz). This frequency range essentially covers the spectrum from far infrared…

In the Fizeau-Laurent system, monochromatic light (light of a single colour) is passed through a pinhole and illuminates a reference plane and a workpiece directly below it. The light beam is perpendicular to the workpiece. By maintaining a slight angle between the surface of the workpiece and the surface…
