Infrared Spectral Ranges For Imaging Application - 785 Words

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 images of simple biological samples such as onion cells to study a resolution and other potential functions of the home-built microscope. Introduction: An optical microscope is an instrument that allows us to view micrometer scale objects in a larger image. [Carl Zeiss] The microscope uses a compound lens which allows to get maximum magnification. The compound lens is made up of multiple lenses that have a common axis, allowing for a high magnification to be possible. The microscope consists of objective lens and eyepiece. The objective lens is a vital part of a microscope since the lens provides a few different variations of power for magnification, and the eyepiece magnification power helps multiply the objective lens power, which will create a large amount of magnification. However, a microscope image is limited by a lens material. Glass (fused silica) is only transparent to visible light and it cannot be used for infrared light. Recently, infrared imaging has been usedShow MoreRelatedThe Impact Of Food Quality On Food Industry912 Words   |  4 PagesMachine vision, as a novel non-destructive analyzing technology, has been widely studied and employed in various industries (Davies, 2012). It can be applied to inspect raw materials or products during manufacturing (Davies, 2013). Recently the applications of machine vision in food industry are increasing rapidly since the developments in camera technology and the processing power of computer hardware (Chen et al., 2013).

Raw spectral data processing was performed in order to minimize the differences between specular and diffuse reflectance due to cell size and shape, but also due to the varying thicknesses and densities of the bloodstains. This step was undertaken to ensure that minimum variation in measurement of stains of the same age occurs. Spectral feature selection by Fisher s weights was employed in order to obtain those spectral points most important and indicative ofRead MoreThe Principles Of Laser Doppler Flowmetry 21657 Words   |  7 PagesPrinciples Of Laser Doppler Flowmetry 2 Clinical Applications 4 Recent Developments 4 Glossary 5 Works Cited 6 â€Æ' Introduction and History Laser Doppler flowmetry, or LDF, is a unique way to measure the microcirculatory blood flow without a painful or invasive procedure. LDF uses the Doppler shift theory as a way to transmit the information, with the scattering of light coming from the laser by way of the red blood cells.
