Optics has many uses in the world. One of the many uses is in contact lenses which work the same way as glasses. For myopia or nearsightedness, the lenses diverge the light rays since they meet too early in the eye. For hyperopia or farsightedness, the lenses converge the light rays.
Fiber optic cables are starting to be used for marine biologists exploring the deep sea. Since electrical lighting in water is extremely dangerous, fiber optics provide a safe, clean and efficient way to create light.
Scientists are researching the use of magnets to steer light which can lead to a faster communications than fibre optics.
MIT researchers have developed a novel “photonic” chip that uses light instead of electricity — and consumes relatively little power in the process. The chip could be used to process massive neural networks millions of times more efficiently than today’s classical computers do.
Novel optical neural networks, which use optical phenomena to accelerate computation, can run much faster and more efficiently than their electrical counterparts.
MIT researchers describe a new photonic accelerator that uses more compact optical components and optical signal-processing techniques, to drastically reduce both power consumption and chip area. That allows the chip to scale to neural networks several orders of magnitude larger than its counterparts.
People don't often realize that optics surround them in their every day life. A lot of technology has been developed from using optics, including lasers. The powerful beam of light allows for various applications in the fields of science, research, and industry. Lasers can open up a treatment option for cancer patients, be used to scan barcodes, and even exists as printers. Understanding the optics behind these highly concentrated energy can help us use it for our interests.
This article talks about how optics relates to optometry and it use in the medical field. It is important to see how without optics, everyone would not know a reason why some people cannot see images clearly or why people wear glasses.
This article talks about how metasurfaces can perform tricks of light far beyond what traditional curved lenses can do. Engineers etch individual features, hundreds of times smaller than the width of a single human hair, onto these metasurfaces to create patterns that enable the surface as a whole to scatter light very precisely
This article talks about optical components designed to focus or diverge light. It also talks about how many industries use optics including life sciences, imaging, industries, or defense.
One of the most notable applications of optics is the digital camera, which can be found everywhere. They work by focusing light from the outside using a lens onto a sensor, similar to how our eyes focus light onto our retina. Images can be zoomed in and out by turning the lens, which moves it forward and back, changing the location of the focal point relative to the sensor. When a button is clicked, the camera records the red, green, and blue value of each pixel on the sensor and processes it into a digital image for you to share and enjoy.
Until now it seemed impossible to perform in-depth examinations of cell bonds without extracting tissue from living organisms. Photonic diagnostics optimizes screenings without subjecting the patient to an invasive procedure. Biophotonic methods enable transparent localization of affected areas: Optical Coherence Tomography uses laser radiation to determine material properties as the laser penetrates deep into human tissue layers and provides information on the progression of a medical condition through imaging. Even the smallest indications in the tissue can be detected with laser-based microscopy in connection with fluorescence technology, facilitating treatment at an early stage of progression. This also helps in avoiding unnecessary surgeries and associated risks.
Fiber Optics is when information is in a beam of light. Then the light is sent through a glass or plastic pipe. They are used in medicine to illuminate or create an image. It was developed in the 1950s so doctors could see inside the body without having to cut it open.
Sometimes in just cutting a sheet of metal barely greater than 5mm thick, it is not the best option to use expensive equipment. Carbon dioxide laser cutting, however, is very efficient in this case. They typically emit at wavelengths of 10.6μm, and cut more smoothly and efficiently than fibre lasers. They are pumped via electrical discharges. This goes to show how many large scale companies can use optics for measurements and precise cutting.
Reference (along with other cutting methods with optics):
While human eyes can only see the visible lights, the application of optics in technology has allowed us to see outside of that spectrum. A technology called thermal imaging, which can be used during firefighting, is able to detect infrared rays, invisible to human eyes, that come off of objects in the form of heat. The resultant image allows people to make out the outlines of objects based on how much energy they've given off, even when there is no visible light in the area.
