How to Realize Optical Path Closed-loop Control in Laser Stabilization System

Laser stabilization systems can be used to counteract or correct optical path changes caused by external vibrations or other factors, which plays a vital role in imaging, optical communication and other applications. The most common approach is to use electrical feedback loops, such as the PI or PID type. Electro-optical modulator can be used to control power, and the servo system bandwidth is very high. Reasonable design of feedback circuit is very important to achieve effective noise suppression in a large bandwidth range...

CoreMorrow Piezo Mirror Mount/Mirror Adjustment Mount by Stick-Slip Principle

With the development and progress of piezo application technology, piezo products are used in more and more experimental environments. Mirror adjustment mounts are very common in many laboratories. Traditional optical adjustment mounts use manual adjustment of threaded screws to adjust the deflection angle of the mount, and the appearance is similar to the figure below. Although the price and cost are low, there are many adverse effects, such as the inconvenient operation and the low precision....

Approaching Piezo - CoreMorrow Piezo Objective Scanner

The name of piezo objective scanner is actually derived from the combination of its driving principle and application purpose. "Piezo" refers to its driving principle, that is to use piezo ceramics as driving source to generate movement. And "objective scanner" is its application purpose, to adjust the movement with the carrying lens. But in general, the piezo objective scanner itself does not contain any lens, it can carry different types of lens according to the actual use requirements. Piezo objective scanner is also called piezo objective driver...
