PPT-Light, Color and Imaging

Light The Electromagnetic Spectrum E h n Light Color When light impinges on a surface lots of things can happen e of the atoms absorb some of the photons Followed by possible vibrational relaxations in excited states.

Also. , the character of surfaces created by the response of vision to wavelengths of reflected light.. When Light Strikes an Object. When light strikes an object, the light can be . A. bsorbed (. take it in. ). R. eflected (. bounce off/scatter. ). T. ransmitted (. carrying it/moving it. ). Materials can be classified as. Color. Color is:. A property of light. Visible when light is emitted or reflected. Determined by the wavelength of light. The three properties of color are hue, value and saturation.. Hue. refers to the pure state of a color; it is the name we give a color, such as red or blue.. Properties of Light. When light strikes an object it is:. Reflected. Properties of Light. When light strikes an object it is:. Reflected. Transmitted . Properties of Light. When light strikes an object it is:. How do humans sense light? . Provide an example “stimulus-sensor-coordinator-effector-response” framework using human eyes as the color sensor.. Give some examples of color sensors in engineering systems.. 1Many different types of light microscopesare available each with their own strengths and limitationsA main tenant of good microscopy is to select the right tool microscope for the job at handPlease c Camera Camera window Half mirror Light irradiationOptical axis of the camera lensStructual diagram Image when mountedon the Light Unit Application ExamplesInspecting electronic parts on the PCB Imagin Adrenal glands can be affected by a variety of lesions. Adrenal lesions can either be primary, of adrenal origin, or secondary to other pathologies. Primary adrenal lesions can further be either of cortical or medullary origin. Functioning adrenal lesions can also give clues to the histologic diagnosis and direct workup. Over the years, various imaging techniques have been developed that have increased diagnostic accuracy and helped in better characterization of adrenal lesions non-invasively. In the first part of the two part series, we review adrenal imaging techniques and adrenal cortical tumors such as adenomas, adrenocortical tumors, adrenal hyperplasia and oncocytomas. Why do we see what we see?. Color. The property possessed by an . object. of producing different sensations on the . eye. as a result of the way the object reflects or transmits . light. .. Light. transmission. Light = straight path. . absorbs energy as its electrons. move from a low to a high energy level.. An atom:. emits light when an electron moves from a high to a low energy level..  .  . Learning Goals. Black is the absence of light.. This font is black because no light is shining here. . The light shines all around it making white. . Mixing colors. By mixing different colors you can create new colors.. INTD 302. ASSOC PROF DR NOOR HANITA ABDUL MAJID.
