The luminous intensity or direct ratio in source, the square distance with the face to the light source that are illuminated are inversely proportional.And receiving terminal is using photosensitive three
Pole pipe, volume also very little, can be approximated to be a point, it is possible to regard vertical irradiation as, so the illumination E of receiving terminal with send
The luminous intensity I relationships at end are：
In formula d be transmitting terminal at a distance from receiving terminal, as LED is at a distance from optical receiver apparatus in the present invention.
Receiving terminal can be considered ideal point, and by transmitting terminal vertical irradiation, therefore reception power and receiving terminal illumination are directly proportional, if
Proportionality coefficient is β, and reception power is Pr, then receiving power and receiving terminal illumination has following relationship：
Pr=β E (4)
The emitter output current of receiving terminal phototriode and light receiving power PrIt is directly proportional, if proportionality coefficient is γ,
Related with the photosensitive material of phototriode and amplification coefficient, measuring circuit output voltage is U, then output voltage and light-receiving work(
Rate meets：
U=γ PrR (5)
Simultaneous formula (1), (2), (3), (4), (5) obtain the quantitative pass of final output voltage and transmission, receiving terminal distance
System, i.e.,：
For formula (6), when LED, phototriode model are selected, and drive circuit power is constant, molecular moiety is
