概要

• 論文の詳細を見る

• A new focus error detecting method for an optical disk drive has been developed using a holographic optical element (HOE). The groove pattern on the HOE was designed using the ray-tracing and least-squares-fitting methods to attain a symmetric beam profile. It has been proven successfully that this method of focus error detection is insensitive to wavelength fluctuations, objective lens shifts, and tracking grooves.
