This circuit is designed to detect very weak light pulses lasting 1uS. It uses a tuned
LC feedback network to provide high sensitivity while giving high ambient light
immunity. A post voltage amplifier is included with a gain of about X20. The circuit
is described in more detail in the receiver section of my
Handbook
of Optical Through the Air Communications. Note: The LF357 op amp is no
longer available, this circuit is for reference only.
