Abstract

We experimentally demonstrate a simple, effective and intelligent scheme to obtain image monitoring of femtosecond laser processing of biological hard tissues. A simple mobile phone camera is adopted for imaging of different processing status of biological hard tissue. Subsequently, an automatic recognition method based deep learning is proposed to recognize the relationship between the optical images and manufacturing effect for the fast parameter optimization of laser processing. Correspondingly, the laser processing parameter could be well controlled to obtain qualified laser processing of biological hard tissue. These results indicate an efficient and accurate image monitoring route for intelligent femtosecond laser processing of biological
