    Abstract: An optical pickup for correcting an astigmatic difference of a light by using a collimating lens arranged at an angle with respect to the thickness direction of an active layer of a light source and parallel to the width direction of the active layer, for collimating the light emitted from the light source, is provided. The collimating lens is arranged between an edge emitting laser diode having an active layer and a beam splitter, and corrects the astigmatic difference of the light emitted from the edge emitting laser diode. Therefore, a compact optical pickup can be achieved since additional optical elements for correcting the astigmatic difference of the laser beam are not required.

    Abstract: A method for monitoring an ion implanter includes positioning a substrate behind an interceptor for intercepting a portion of an ion beam to be irradiated toward the substrate, irradiating a first ion beam toward the substrate to form a first shadow on the substrate, rotating the substrate about a central axis of the substrate, irradiating a second ion beam toward the substrate to form a second shadow on the substrate, and measuring a dosage of ions implanted into the substrate to monitor whether the rotation of the substrate has been normally performed. Preferably, a dosage of ions implanted into the substrate is calculated from a thermal wave value of the substrate and whether the rotation of the substrate has been normally performed is monitored by comparing the thermal wave value corresponding to the first shadow with a reference thermal wave value.

    Abstract: A method of recording holographic information includes recording a hologram mark and a homogeneous mark in a holographic data storage medium with a volume to alternatively locate the hologram mark and the homogeneous mark. The hologram mark has a varied refractive index distribution due to constructive/destructive interferences between two light beams and indicates information, while the homogeneous mark has a more uniform refractive index distribution than the hologram mark.
