Hi,
I am currently designing a photo detector circuit which would give out a TTL pulse in response to a black or white image on a screen changing at 30Hz. Since I am an amateur at electronics I have been looking on the internet for ideas, and came across this particular circuit

But I am not able to decide if this could be of use to me. And also if the circuit is this simple.
Could anyone advice me on this ? Any suggestions on other possible circuits/ideas is also appreciated.
Thanks in advance.
