Annotation: We developed a system for measuring nano scale movements of micro and macro objects based on an adaptive holographic interferometer. The measuring system based on an adaptive interferometer allows the stable registration and measuring movements of micro-and macro-objects in the range of 1.7 to 266 nm at speeds of tens of nm / s to a few μm / s.
