Mathematics of Lenses and Optical Glass

– Missing figures PROPERTIES OF LENSES, OPTICAL GLASS Composition Glass is a solid, structureless and amorphous. There are two main group classification of optical glass: 1. Crown, and 2. Flint (has a high content of lead oxide) Chemicals are combined to produce new glass types. These new glass types are used to benefit other different types of cameras (such as high-speed minature cameras, black/white cameras, etc). Properties The most important optical characteristics of a glass are its refractive index and its degree of dispersion….  

Effects of Google Glass on Society

– In February of 2013, Google announced project Glass. Glass is a wearable computer with an optical head-mounted display so the wearer can see everything without moving their head. There is no screen on Glass, it uses a small mirror prism to bounce information directly into the wearer’s right eye. To transmit sound to the wearer, Glass vibrates the skull which then transfers sound to the inner ear so that the persons normal hearing abilities are not impaired. For ease of use there is a small touch-pad on the outside surface of the device, around the ear area….  

Optical Sensors

– Introduction- An optical sensor is a device that converts light rays into electronic signals. It measures the physical quantity of light and translates it into a form read by the instrument. One of the features of an optical sensor is its ability to measure the changes from one or more light beams. This change is mostly based on the alteration of the light’s intensity. Optical sensors can work either on single point method or through a distribution of points. The major importance to the proper use of an optical sensor is that it retains certain facets of measured properties….  

Worker Health and Safety in Bangladesh

– Workers Health and Safety Not only do the United States Companies have obligations to workers who produce apparel they market. More importantly, these Americans businesses have authority to correct unlawful violations. In addition, customers rely on merchants’ good will and standing when evaluating the makers of their products. For example, according to Sherman (2013), those global clothing buyers, mainly the United States companies, have a job to execute guaranteeing security of Bangladesh’s apparel workers”….  

Optical Fiber Sensors

– … 2012) and environment(Mothersill&Seymour 2014), but also can damage the electronic devices(Wang et al. 2014). The source of these ionizing radiations are from radioactive materials, x-ray tubes, particle accelerators such as ion beams, nuclear weapons and reactors, cosmic rays from space and from natural rocks and minerals. Exposure of extremely high energy electromagnetic radiation such as x-ray can lead to failure in silicon sensors(Klanner et al. 2013). The increasing radiation induced attenuation can lead to permanent damage of optical fiber(Kovacevic et al….
