INTRODUCTION
LIGHT SOURCES
This demonstration board makes it easy to explore the operation of a photodiode
application. Items discussed in this chapter include:
• Light Sources
• Using the Signal Analysis PC Program for this Board
• Stand-Alone Board Set-up
Different types of light sources have different characteristics. DC-powered light sources
have a constant output intensity. AC-powered light sources have an output intensity
that varies with time around an average value.
A battery power light source will have minimal fluctuations in light intensity. A
battery-powered flashlight or LED array are good DC light sources.
Incandescent light bulbs and flourescent lights powered by the mains (e.g., 120 VAC at
60 Hz) are typical AC light sources.
When making light intensity measurements, other light sources in the environment may
need to be blocked to achieve better measurement accuracy. Place a box over the light
source, the demo board and on top of the bench to keep out ambient light; see
Figure 3-1.

See “Chapter 2. Using the PICkit™ Signal Analysis PC Application” of the “Signal
Analysis PICtail Daughter Board User’s Guide” (DS51476) for details on displaying
measured results. The possible formats include: oscilloscope, FFT, histogram and
strip-chart.
The measured results can then be interpreted as illuminance; see AN951, “Amplifying
High Impedance Sensors – Photodiode Example” (DS00951).
