5 INTENSITY CALCULATION MODE

Intensity = (Vo x Distance

) / (Area x Responsivity x R1)

Vo (volt) = VH - VL (based on the waveform displayed on oscilloscope)

Distance (cm) = distance between Photodiode and DUT (Device Under Test) = 30cm

Area (cm) = area of Photodiode = about 1cm

Responsivity (A/W) = 0.6034 A/W (the average responsivity over 850 through 900 nm)

R1 = 500 ohms

So Intensity can be expressed as :

Intensity = (Vo x 30

) / (1 x 0.6034 x 500) = Vo x 2.983 mW/sr

(Because the Area, Responsivity and R1 are all fixed values, the constant 2.983 will only be

changed when distance has been changed from 30cm.)
