Here’s a design circuit for light pulse receiver
circuit that is used to detect very weak light pulses lasting 1uS. In the figure at below is a figure to
show the schematic diagram circuit;
This circuit 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.
