Although there are many different types of tools that are used in business, lasers are one that certainly should not be overlooked. After all, laser tools provide a higher degree of accuracy than standard tools and they can also often get jobs done much faster than other types of tools as well. This is true of laser cutters that are used in many industries and in the medical field as well as laser measuring devices that are used in manufacturing and industry as well. Here are a few of the uses of lasers in science and industry that touch our lives in many different ways.
One of the ways that lasers are used in science is in performing distance measurements over great lengths. For example, there was a time when it was only estimated how far it was from the earth to the moon but now, thanks to various laser tools, it is known how far it is to a very accurate degree. The astronauts placed a mirror on the moon which allowed the scientists that were on the earth to bounce a laser beam off of the mirror and send the reflection back to their laboratory. This permitted them to discover the distance from the Earth to the moon within a matter of inches. Since laser light travels at the speed of light, they were able to determine the length of time that it took for the laser to reflect off of the mirror back to their laboratory to determine a very accurate measurement of that distance. Of course, the distance from the earth to the Moon does change on almost a constant basis but having an accurate depiction of the distance allowed them to know how the earth and the moon interact in different ways.
Distances are also measured by lasers on a much smaller scale here on the earth. Surveyors, for example, make use of lasers and infrared light in order to determine distances from one point to another. The accuracy that is available is much greater than using the chains that were used to measure those distances just a few short years ago. There are quite a few variables which will make a difference in the calculations for the distances, including the temperature and even the humidity. The accuracy that is available, however, makes it possible for a lot of building projects to take place, including deep excavations, drilling wells, laying pipelines and erecting skyscrapers.
Lasers are also used in many other ways in industry as well as in science. This includes cutting, which can be done much more accurately and much more neatly than using standard tools which were used for that purpose a few decades ago. The type of cutting which can take place is also possible on a variety of different surfaces, including woods, metals, plastics, cloth and ceramics. The cutting can either take place in one direction across the surface of the material or it can be used for drilling holes into the material directly. This has allowed for more accurate and faster manufacturing of various products which we all use in our day-to-day lives.
