3 Applications of Optics You Should be Aware of

This article enlists the application of optics below.

Image forming

The applications here are classified in three groups, the image forming applications, non image forming applications and the hologram deemed as an optical element. It is inevitable that these groups align to the basic use of the process instead of particular holographic tactics. The first group has those applications that uses image formation when normal coherent or coherent image formation are not enough. It is not enough to replace a normal image being processed by the means of holographic technique unless there are some benefits to it. The needed record can be gained more easily or more correctly. Applications included here are the holographic microscopy, particle size analysis, high speed photography, data storage and retrieval like displays, image formation by a random medium and non optical holography like acoustic holography.

Non image forming

The second group involves those applications that are not image forming. One of the exciting applications here is to nondestructive testing of the materials. For instance, testing of tires is done for the flaw detection or debonds that are present between the plies of the tire. Hence, the department of the interferometry is extended to new classes of objects. In a similar but separate development, there has been a huge success for interference microscopy.

Optical elements

This entails the building of perfect and particular gratings and application of holographic filters in optical data processing. Holography can be modified by including a separate reference beam so that the light being diffracted by the object in the microscope can interfere with the light coming from reference beam. You can increase the depth of field with this recording process. Then the image is produced when the hologram is lightened up by a coherent beam. The application of holography to particle size analysis is the very first modern day application. This can also be deemed as microscopy. As the particles are in motion, an instant hologram is made. This uses the pulsed ruby laser technique. The hologram created between the light diffracted by the particles and the coherent background light that permeates directly via the sample. When it comes to reconstruction, a chain of stationary images are created that can be examined. Hence, transient event is transformed into a stationery image for evaluation.
