Re: Part II: Understanding & Using Sensors in Machine-Vision Systems

NO RATINGS
Q. What of the effect of the medium on the light path.....refraction, dispersion attenuation?...... on effectiveness of the sensor.

With vision sensing a great question. In non industrial applications such as automotive these all can play a limiting role of the effectiveness of the sensor. In fact, to overcome the limitations two different sensing techniques are often used for vehicles that need to sense traffic for warning systems. vision and radar or lidar are the choices fro these applications. In industrial, I would expect that the variations in the operating enviroment would ahve to be considered under extrme cicumstnaces. I have seen little about them causing a non functioning system.
