A photo diode consists of a p - n junction coated with
translucant film . The light (radiation) is allowed to fall upon
its surface, across the junction. The junction is made reverse - biased
with an e.m.f source. A reverse current flows nearly linearly
with the intensity of light flux.the reverse - biased current flows
through diode is linear function of light intensity, thus to measure
the light intensity level, this current is passed through a precision
fixed resistance R. The reverse current devlope propotional voltage
across the R, which is than amplified to desired level by an amplifier.
