Optics

What is interesting is that he writes about how photography is a process of taking what we already see, it is based on selection not synthesis. We do not get to create what we want to see when taking photos of the world, is all about how we see it that makes a photo interesting, “the world itself is an artist of incomparable inventiveness,” (Szarkowski 3). So a photographer’s job is to see the art that the world has created and to capture it, to express what he has seen. This shows us that…

If you enjoy the sport of shooting with an AR-type rifle, Bushnell has a riflescope designed with you in mind. Their AR Optics 3-12x40 mm scopes are caliber-specific to give the most accurate performance for the ammunition you like to shoot. This particular model is engineered to give outstanding results with AR223 bullets. This Bushnell AR Optics scope is made of a black aluminum alloy with an anodized finish. It looks great on a gun, and the matte finish means that it will not catch the sun…

Many diverse emotions and physical feelings were involved during my contrived experience. Before simulating monocular vision due to Arteritic Anterior Ischemic Optic Neuropathy (NAAION), I did not anticipate the increased level of difficulty that certain normal activities of daily living (ADLs) and instrumental activities of daily living (IADLs) would have on my day. My experience consisted of an eye-patch covering up my left eye for 12 hours. Some of the activities I found to be the more…

is only natural that the great thinkers of antiquity were curious about the nature of vision, and inseparably, that of light itself. In the manner characteristic of ancient science, many common ideas about optics were “hit or miss”, so to speak. Certain Greek thinkers had hypotheses about optics which are more or less in line with modern principles, but many held firmly to ideas which are at odds with the current understanding of reality. I discuss extramission theory (a hallmark of Greek…

Fiber optic communication systems are light wave systems that employ optical fibers for transmitting information from one point to other through an optical fiber. The driving force behind the widespread use of fiber optic communications is the demand for economic, reliable transmission media that can transmit required information capacity. The transmission capacity of optical fibers has drastically improved over the years. Today, optical communications up to 100 gb/s for several kilometers have…

When a lens produces an image, the size of it corresponds to the focal length of the lens. The smaller the focal length, the smaller the image and the longer the focal length the bigger the image. How bright an image may be solely depends on the amount of light collected by the objective lens. How much light can be collected corresponds to the area of the objective lens. So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you…

Electron motion in atomic systems, which happens on timescales of attoseconds, is at the heart of all phenomena in nature (except for nuclear processes). Electron motion is responsible for the emission of light and photosynthesis in plants. Electron motion across biological molecules transports information in our nerves and is involved in processing this information in our brains. Moreover, the valence electrons are responsible for binding atoms to form molecules. The structural change of…

1. Doppler radar systems provide information about the movement and position of targets. They work by sending a beam of electromagnetic waves at a specific frequency, at a moving object. When a microwave bounces off the object, its wavelength shifts as the object moves (this is known as the Doppler effect). The radar detects the shift and calculates how fast the object is traveling, along with it's location. 2. Polarized sunglasses block reflected light (glare). Since polarized light waves…

A light microscope works like a telescope using glass lenses to reflect light, which magnifies images which are naked to the human eye such as cells and dust. The lens closest to your eye is called the eyepiece lens. This usually has a magnification of x10. Objective lenses are lenses of several different strengths which magnify the image. The stage is the place where the microscopic slide sits. This is held in place by the clips. The light source (can be a mirror or a bulb) projects light onto…

Crane’s description of the bar where Pete works subtly highlights the deceptiveness of this bar’s appearance. The words “imitation leather” depict the fake or misleading qualities of the bar. The “massiveness” of the “shining bar” is another deception of appearance as the “mirrors set in the face of the sideboard” make it look larger than actuality. The mirror also “multiplied” the number of “shimmering glasses” giving the feeling of elegance and high quality. However, the glasses were never…
