Study of solid-state microchip laser feedback technology in remote vibration measurement
The technology of laser feedback has ultra high sensitivity and great advantages in vibration measurement. Based on laser feedback theory and technologies, method of remote vibration measurement with laser feedback technologies was studied and presented. The remote vibration measurement system based on microchip solid-state laser feedback was built, the structure and working principles of each parts of the system were studied in detail. The vibration signals of different frequencies in experiments were measured and restored. The working distance of vibration measurement was improved to 25 meters, realizing non-contact measurement of remote vibration. The application of laser feedback technology was expanded. The experimental system has superior performance and large range of amplitudes and frequencies in vibration measurement, and it can be applied in various occasions and can meet various target measurement requirements.
