What kind of AOM should be used for DAS systems?
So if you want to modulate a narrower pulse width, the rise time of your AOM must be matched. Otherwise it is theoretically impossible to modulate a narrower pulse width due to the AOM's rise time.
Distributed fiber optic acoustic sensing system tests different vibrations with PZT and restores the signals.

Video of a test of the effect of a DAS-reduced signal using a PZT to generate vibrations of different frequencies for excitation of an optical fiber.
how to make distributed fiber-optic sensors for vibration detection?
We provide all the hardware needed for cost-effective distributed distributed vibration sensing systems, including integrated modules, as well as components such as lasers, AOMs, and acquisition cards.
In addition to providing DVS/DAS modules, we also provide free after-sales technical support services, we have many years of research and development of the whole machine and a wealth of field experience, which is equivalent to have helped you solve the various difficulties in the process of DVS development and implementation in advance, saving you at least 1.5 time and energy.
