- 論文の詳細を見る
We have developed Blu-ray disc (BD)/digital versatile disc (DVD) compatible technology employing a polarization-free wavefront correction element. The polarization-free wavefront correction elements have high diffraction efficiencies for both BD and DVD. Also, this element has a large decentering tolerance for the objective lens. The effectiveness of this element was confirmed by examining wavefront aberrations for DVD and readout signal waveforms for both BD and DVD.
