    Pyroelectric Detectors

    Pyroelectric detectors Pyroelectric Infrared Detectors (PIR)convert the changes in incoming infrared light to electric signals. Pyroelectric materials are characterized by having spontaneous electric polarization, which is altered by temperature changes as infrared light illuminates the elements. Since our sensor series uses this effect they can be used at ambient temperature even in the presence of thermal noise. By choosing appropriate IR receiving electrodes

    Film Form Analysis

    Film Form and Analysis Cinematography Cinematography describes the process by which a film strip is exposed to light to create an image. It encompasses many factors: the camera’s distance from the action, camera angle and direction, type of lens, camera movement, and lighting, among others. The art of cinematography also includes mise-en-scène—the arrangement of objects and movements in the frame. Shot Types The amount of visual information included in the image depends on the distance of the

At a more macrostructural level, the grains become markedly elongated in the direction of working and heavily distorted. This distortion is evident from a bending of annealing twins and from unevenness in etching caused by local strain inhomogeneities. While the increased hardness and strength that result from the working operation can be important, it is often necessary to return

    What Is Photo Journalism and Its Effect to the Community

    THE APERTURE is referred to the lens diaphragm opening inside a photographic lens. The size of the diaphragm opening in a camera lens regulates amount of light passes through onto the film inside the camera the moment when the shutter is pressed in camera opens during an exposure process. The size of an aperture in a lens can either be a fixed or the most popular form in an adjustable type (like an SLR camera). Aperture size is usually calibrated in f-numbers or f-stops. i.e. those little

    Optical Distortion Inc

    Optical Distortion, Inc. (ODI) is the world’s first company to introduce contact lenses for chickens. These lenses offer farmers a unique cost saving opportunity and are more humane and efficient than the current de-beaking method. ODI, with help from New World Plastics has developed this commercially viable technology to reduce cannibalism by inducing astigmatism. With a patent holding off competition for at least three years, ODI needs to decide how to price contact lenses to ensure high adoption

    Iron Solutions: Developing New Algal Growth Media for Increased Iron Uptake

    requirement, minimizes the loss of inorganic carbon through escaping CO2. The cells were grown in four different media (iron free, 30uM FeEDTA, 10um ferrous sulfate, and a combination of the two). The growth of the N oculata. was primarily measured using optical density testing during the logarithmic growth phase. After one week of growth the highest biomass density, 0.86, observed in the culture grown in 30uM ferric EDTA, was more than 2.5 times the lowest, 0.333, which was found in the culture containing

This new format has arrived with the advent of Blu-ray Disc, the only format that offers a considerable increase in storage capacity with its 25 to 50 GB data capacity. This allows for the next big application of optical media: the distribution and recording of High Definition video in the highest possible quality. In fact, no other proposed format can offer the data capacity of Blu-ray Disc, and no other format will allow for the same high video quality and interactive
