摘要: | This Letter presents an optical module with a holographic optical element (HOE) for the small-form-factor pickup head. The proposed module is mounted on a novel seesaw swivel-drive mechanism with unique features, including a rotary actuator for track-following; in addition, a seesaw arm nutates along a pivot for laser focusing. Additionally, the actuating force is increased within the limit of actuator size constraints by using a Halbach-magnet-array in biaxial voice coil motors. Experimental assessment of the holographic module and actuator reveals that the HOE module ensures the optical performance and stability of the system, together with a performance superior to a classic hinge-type swing arm actuator, as attributed to enhanced durability and higher robustness. |
