And in Indirect Incidence, both the IR LED and Photo diode are placed in parallel (side by side), facing both in same direction. In that fashion, when a object is kept in front of IR pair, the IR light gets reflected by the object and gets absorbed by photodiode.
Photodiodes with a p-i-n structure are also used. Such photo-diodes have characteristics similar to those of p-n photodiodes, but their rise time is substantially smallerâas low as 10 â10 sec. Photodiodes are used, for example, in automated devices, laser technology, computer technology, and measurement technology.hen operating in the first mode, a photodiode is used as a photoconductive cell to control the electric current in a circuit in accordance with the variation in the intensity of the incident radiation.
