Measuring Average Power
Although the Pyroelectric sensors are designed for energy measurement, they can be used to
measure average power as well using the formula:
Average Power = Average Energy X Frequency
where the energy and frequency of the pulses have been measured by StarBright.
Note:
StarBright use when measuring power is the same as when measuring energy and has been
described in full in section
Operation of StarBright with Pyroelectric and Photodiode Energy
To measure average power:
1.

Average power will be displayed as a function of “Energy x Frequency” on the screen as well as
the laser’s frequency.
