Fiber Optics Essay

Quantum optics tells us that left (l)- and right (r)-circularly polarized (CP) photon conveys "integer" spin angular momentum, +ℏ and –ℏ, respectively, although photon is massless elemental particle. The nature of "integer" spin obeying Bose-Einstein statics makes plural spins confine in an ultrasmall temporalspace with the same quantum state, meanwhile, "half integer" spin like electron denies to share the same quantum state in a molecular space, well-known as Pauli exclusion principle. Intense

Two painters in history are known for their abilities to depict scenes in such realistic manners that you would never know they are actually producing paintings. These painters are named Johannes Vermeer and Albert Bierstadt. Both men came from different times and ethnic backgrounds. Dutchman, Johannes Vermeer was born in the year 1632 and passed away in 1675. Over his lifetime Vermeer used a style of painting that causing modern day historians and art lovers to struggle to figure out how he painted

Olivia Silvestri Due: 10/19/15 Using a Compound Microscope Lab Report E Period Abstract The purpose of this lab is to learn about the parts and uses of a compound microscope. It is also to learn how to properly use and take care of the microscope. This lab showed me what materials and parts of the microscope I should use when examining an object. Introduction The microscope was invented by a father

Catadioptric: Catadioptric telescopes are those that use both mirrors and lenses to produce an image. The most common or popular type of catadioptric telescope is the Schmidt-Cassegrain telescope. Schmidt-Cassegrain telescopes (SCT) are a catadioptric design, meaning they use both lenses and mirrors. SCTs are primarily reflecting telescopes, but they use a corrector lens to eliminate aberrations that would result from the mirror design alone. In an SCT the incoming light passes through the Schmidt

I am Qingjun Wang, currently a senior at Hunan University, majoring in Electronic Engineering. Began my journey into the field by studying in Physics and Microelectronics department of Hunan University, where physics ranks in the top 1% of ESI global discipline. Studying on this topic, which I am very much interested in, led me to excel in my program, earning me a GPA of 90.3 on a 100-point scale, which ranked me as the top student out of the 112 who are in my program. My life over the last three

Fantasy will always be more cherished than reality. Our imaginations give way to disappointment when it's time to buckle down and come back to the real world. However, for Nellie this is quite the opposite. In Anton Chekhov’s “The Looking Glass” character development, symbolism, and diction are used to communicate that reality upsets our expectations. Character Development is one of the most effective tools used to communicate the overall theme of The Looking Glass. Character Development is used

Key Advantages of the Keyence VHX-6000: • Advanced Focusing • Accurate Dimensional Measurements • Contamination Analysis in line with ISO 16232 Standards • 3D Display and Measurement The Keyence VHX-6000 microscope has been found to have many of the key aspects needed to analyse and quantify sub-surface defects on samples taken from the GKN traveller specimen. It has many advanced capabilities that lead it to producing sample images of exceptional quality. A key requirement in this task was

Abstract: Infrared imaging is widely used in biochemical sensing, medical diagnosis, and astronomy. In this summer High Scholar program, we will develop reflection microscopy working at wide infrared spectral ranges for imaging application. Reflection microscopy is based on gold coated parabolic mirrors which make the microscope accessible to visible, infrared, and even terahertz light without chromatic aberration. Here, we will design and build a reflection microscope, and obtain visible and infrared

2. Background on the mineralogical composition of petrified woods A diverse suite of minerals and phases have been found in petrified woods from all over the world. The common species found range from pure opal to pure quartz whereas others include calcite, dolomite, pyrite, goethite, phosphates (apatite), laumontite, uraninite, sphalerite and organics (Nowak et al., 2005). In coal deposits inundated by sea-water (Yossifova et al., 2011), the woods can be permineralized by quartz, plagioclase, muscovite

The ability to become young again, live forever, and to heal any wound has been discovered in 1991! Ron and Tom are archaeologists from Australia, and their latest mission is to retrieve the Crown of Life from the Tomb of Neferkheperuhersekheper located in Egypt. Whoever wears the Crown of Life will become young, never die, and heal you whenever you get hurt. Ron and Tom arrived at the entrance to the tomb. They put on their packs filled to the brim with their gear. The map showed that there were
