difference between the infrared camera and a CCD camera in the system of closed circuit television?
Hello! Can anyone help find explanations in the CCD camera and infrared camera. I have to prepare a report on this project, please
IR = infrared of spectrum light (color). There are two infrared bands used to obtain images. Near-IR is just outside the area of color, we can see. People use the NIR to take interesting photos and can be used to view an unlit area, as perceived by man, which is illuminated by near-infrared light (Man can not see the light source close infrared). This has been used in nature photography and surveillance. thermal-IR spectral band, where the heat is emitted. Thermal-IR is beyond our capacity video. This requires an image sensor and special lenses. Thermal IR camera image of the heat radiating from surfaces. These cameras usually start at $ 10,000 for systems at low prices. CCD = charge coupled device, a type of image sensor used in cameras. CCD sensors can detect light in the near UV to near infrared. sensors CCD can not be used for infrared thermal imaging. Filters are usually placed in front of the sensor to block UV rays and visible and IR spectrum is detected. There are a lot information in the spectra of light and CCD image sensors on the Web.
