Post O scope of signal from gold or diamond

Come on don't laugh i had to ask the question you see the diagram.
A PHOTO TRANSISTOR I had to ask the question.
Now please don't make me laugh at the PHOTO TRANSISTOR SENSOR.:lo l::lo l::lo l:

Laugh, but you don't know why this implementation. This be very happy me!

Laugh, but you don't know why this implementation. This be very happy me!

Ok now let us get back to this LRL stuff.
What is it that hte photo transistor is picking up.
I would like to test this

OK, was simple. Oscilloscope capture the signal and appears a luminous point in the screen. The phototransistor sense this point.

There are two types of electronic LRL: 1. For buried for long time items. 2. In the air or not buried item or buried for short time. The oscilloscope was used for to show this second in air detection type. In the past the second type was common used, not deppendent of phenomenon of long buried items. But as used radio today degenerate impracticable regarding all types of interference, except in closed inland.

What type the signal is being generated?
Is the signal comming from the target ?

I was looking at the LRL and now i see the Photo transistor is being used as a pickup on the scope but what is the detector part is picking up.
also why not up the gain on the scope to see the change in voltage.
Why the photo transistor?

As the detector was not much stages and as the point is in the screen, the more rapidly at hand was a phototransistor and a beep generator (this is common in electronic LRL. And usual in workbench).

Was a type of point.

I use the terminology "signal" just for to refer the umbalance in circuit. No signal was generated by the target in air.
