    Chapter1 Basic introduction 1.1 Introduction Nowadays, in globalization era there are always the foundation of the new technologies features every year. Automatic temperature control system become the most popular features which rapidly gaining its popularity due to its importance to certain applications. This system utilizes in a room that lack of air conditioning system such as in room. The system is designed that is supposed to monitor the temperature inside a room. The automatic system required

  • Advantages And Disadvantages Of Polarizer

    Polarizer A polarizer polarizes the light beam before the light beam interacts with the sample. Compensator A rotating compensator induces phase retardations of a polarization state of the light beam where in the range of wavelengths and the compensator are selected such that at least a first phase retardation value is induced that is within a primary range of effective retardations of substantially 135° to 225°, and at least a second phase retardation value is induced that is outside of the primary

  • Polarization of X-Rays

    1331 Words  | 5 Pages

    Polarization of X-rays was first demonstrated by Barkla. He was performing experiments on the secondary X-ray radiation phenomena (C. G. Barkla 1905). He used a block of graphite that scatters the primary X-ray beam from an X-ray tube. The scattered intensity of the X-ray beam was measured in two mutually perpendicular directions. He denoted the scattered intensity in a parallel direction to the tube axis I_pand the one scattered at right angles I_s. The degree of polarization for X-rays emitted

    commercially. He conceived the idea of two plates that would absorb the light waves that were not wanted and transmit those that were. He then succeeded in aligning millions of microscopic iodine crystals in one direction, thus creating the first polarizer. Land presented a paper on his discovery at a physics colloquium (meeting) at Harvard in February 1932. In June, he left the university, one semester short of a degree, and never returned. Invents "Polaroid" With a Harvard graduate student named

    sources are observed through an optical telescope. Which of the following colours for the sources would best allow their images to be resolved? A. B. C. D. Blue Green Red Yellow 17. Unpolarized light of intensity I0 is transmitted through a polarizer which has a transmission axis at an angle θ to the vertical. The

  • The Effect Of A Light Ray Reflecting

    962 Words  | 4 Pages

    This lab is made up of four different parts. In the first part we will examine the effects of a light ray reflecting at different angles of incident from a convex, flat, and convex mirror. In the second part a light ray will be refracted through a rhombus prism at different angles of incidence. We will measure the angles using a protractor. For the third experiment we will examine the indices of colors as light is refracted through the rhombus. Lastly, we will use polar lens to examine Brewster’s

    camera filters in their toolbox, even though most digital cameras in the market feature white balance control. One of the most important filters in digital photography is the polarizer that works by filtering out glare from shiny objects. The filter also makes the images more saturated and visibly vibrant. This type of polarizer is especially useful in landscape photography. The other popular types of filters include Diffusion filters, Neutral Density filters and Ultra Violet rays reduction filters

    in his or her toolbox even though most digital cameras feature built in white balance. One of the most important filters in digital photography is the polarizer that works by filtering glare out of shiny objects by reducing haze and darkening the skies. The filter also helps make the images more saturated and visibly vibrant. This type of polarizer is especially useful in landscape photography. The other types of filters include Diffusion Filters, Neutral Density filters and Ultra Violet rays reduction

  • Chirality – Isolation of Limonene from Citrus Fruits Essay

    2087 Words  | 9 Pages

    Chirality – Isolation of Limonene from Citrus Fruits Introduction: Terpenes are a large and varied class of hydrocarbons produced by a wide variety of plants. Many essential oils belong to the terpene class. They are made up of two or more five carbon units that are called isoprenes. Limonene is a terpene that can be separated from orange peels almost 100% in the (R)-(+)-limonene form. Other citrus fruits like lemons, grapefruits, limes, and tangerines contain the compound as well. The

    plates. Consequently, to detect spectral interference, and to trace the relative delay between the pulses in different channels, a small fraction (~2.5%) of the broadband beam was directed through a Glan-Thomson polarizer to the entrance of a fiber spectrometer. Because the Glan-Thomson polarizer projects S-and P-polarized components of adjacent channels on the same axis, and adjusts their relative amplitude depending on its angle, it can enable their spectral interference. Spectral fringes were recorded
