Figure 1.3.1 RDI and MRDI Responsivity Curve 1.4 Image Sensor Pixel level processing image sensors are based on the principle that photons induced by charge at the pixel site should be converted to, as nearly as possible, a noise-free signal at the pixel site. The application of this principle produces the lowest possible noise and also allows signal control at each pixel. As is true in other sensors, photons induce charge which is collected on a capacitor at the photo site. In a p

SECTION 2 Camera Hardware Interface 2.1 Installation Overview Before you integrate your camera into your system you should first determine some basic operating parameters such as what resolution you need. Do you know the speed of the object that your camera will be inspecting? One additional point you want to keep in mind is your lighting requirement. One major item that you should identify early on in developing your system is the source of your EXSYNC control signal ( framegr

SECTION 3 Camera Control TM 3.1 Quick Start with the Camera Link Interface Follow your Frame Grabber manufacturer’s instructions when inserting the frame grabber card into your PC. Be sure that you install the correct configuration software that matches the camera that you are using. At this point your camera should already be connected to the DC power supply, and connected to the frame grabber in your PC. Your frame grabber will see our camera and start communicating almost immed
