| Description | We proposed data recording on biological tissues and prostheses for personal identification. The data recording was
performed by femtosecond laser processing with small thermal damage, a clear edge of recording point, and high data capacity. Because the biological tissues and the prostheses have unexpected movements and individual threedimensional shapes, the laser processing system was required to perform the recording with an adaptability and a high-throughput. The adaptability was implemented with a target surface detection system composed of an image sensor with a high-frame rate, a guide laser, and a piezoelectric transducer stage. The high-throughput was realized by parallel laser processing based on a computer-generated hologram displayed on a spatial light modulator. We demonstrate the data recording on dental prostheses. We also demonstrate parallel processing of glass using the holographic femtosecond laser processing. |
