Measurement Of Speed Using Photoelectric Pickup

Speed measurement by photoelectric ( optical ) transducer is a convient method, since many type of photon devices are available. In present set up a photo diode is used as transducer. A photo diode ( in reverse bias mode ) is a device the resistance of which falls to great extent when it is exposed to light radiation.In actual we must describe the system before the transducer. A light emitting diode and a photo diode is mounted in such way that full radiated energy falls upon the diode.
