Because the pulse delay controller on the market has too many functions and is relatively expensive, our research group now wants to build a delay controller by ourselves, but we haven't systematically learned circuit knowledge before, i don't know where to start. could you please give me some advice or guidance? Or, could you please tell me the principle to creat time delay?
You can have a look at chapter 6 of
https://www.ti.com/lit/an/sbva061/sbva061.pdf?ts=1647865472437&ref_url=https%253A%252F%252Fwww.google.com%252F
which gives some basic descriptions and a low cost circuit.
As an alternative: check out

Building will be fun but time consuming. The simplest commercial pulse delay generators will start around 400$ (e.g. TTi TGP110 Pulse Generator).
Success!

These light pulses can be used to learn about the molecules with which they interact. Consequently, pulsed laser spectroscopy has become an important tool for investigating and characterizing electronic and nuclear structure of protein complexes. These spectroscopic techniques can either be performed in the time or frequency domain.
Please have a look at these delay lines: https://www.digikey.com/en/products/filter/clock-timing-delay-lines/688. Using them, variable delays in the ns scale can easily be generated.
For larger delays, a programmable delay generator can be implemented in almost any FPGA.
