I am trying to build a transient photocurrent/photovoltage setup and I was wondering what is the difference between current and voltage preamplifier? Here is a detailed desciption of my setup
I will be providing a a very short laser pulse (5ns) to a photodetector in either open circuit or short circuit conditions and measuring the photovoltage and photocurrent respectively through an oscilloscope by connecting the output of photodetector using a preamplifier and then oscilloscope.
Please let me know
