  2. Someapplications • Barcodereader • Consists of a light source instead of sound, a lens and a light sensor translating optical impulses into electrical ones. • Technology • Laser scanners • CCD readers (charge-coupleddevice) • Camera-based readers • Omni-directional barcode scanners • Cell phone cameras

  3. OCT - OpticalCoherenceTomography Is an optical signal acquisition and processing method. Micrometer-resolution 1 – 15 μm 3D high-resolution images:retina, coronary arteries… Industrial applications: Non Destructive Testing(NDT)

  4. Materials Silicon Suitable for electronic, mechanical, thermal, and optical integration Can sustain harsh (mechanical) handling conditions Crystalline: mechanical properties are uniform across wafer lots Structure:Crystalline, Polycrystalline-polysilicon, amorphous Conductivity: Semiconductor Metals Aluminum Gold, Titanium, Tungsten Platinumand Palladium

  5. Polymers Ceramics
