摘要： An optical pickup head is provided, including a laser diode set, an optical element set and an optical signal detector. The laser diode set is a laser light source capable of emitting single wavelength, two wavelengths or three wavelengths laser lights. Optical element set includes a low reflectivity beam-splitter and an objective lens. The low reflectivity beam-splitter has an average reflectivity ranging from 10% to 30%. After reflected twice by low reflectivity beam-splitter, the light fed back from recording medium to the laser diode set is reduced to avoid laser noise problem. Moreover, with the optical signal detector having a tilt θ ranging from 3° to 15° to optical axis, the optical signal detector can directly reflect the incident laser light into a different direction so that the reflected light will reduce the feedback light to the laser diode set.

摘要： An optical pick with a reflective coating device is provided, including a laser diode (LD), an optical element, and a photo detector integrated circuit (PDIC). The LD emits 1-3 lights with different wavelengths but the same polarization orientation. The beam transmits the optical element set and focus on a recording media for data reading and writing. The beams are reflected by the recording media, through the optical element set, and detected by the PDIC for signal detection. The optical element set further includes a grating, a reflective coating device, and an objective lens. By using the reflective coating device to change the linear polarization orientation of the emitting light and the feedback light for 90° angle, the relative intensity noise caused by the feedback light in LD can be reduced.

摘要： A calibration apparatus and method for optical system assembly is provided, applicable to a finite conjugate optical system to determine the optimal image-forming positions of the light source and the focus object lens of the finite conjugate optical system. The apparatus includes an external light source, a low magnification image-forming optical system, an electrical control system and a monitor. When the parallel beam generated by the external light source is parallel to the optical axis of the finite conjugate optical system, the low magnification image-forming optical system is used to magnify the two focal spots formed by the external light source and the internal light source of the finite conjugate optical system to be calibrated. Finally, by adjusting the related position of the focus object lens or the internal light source of the finite conjugate optical system, the optimal relative positions between the light source and the focus object lens of the finite conjugate optical system can be found. The calibration apparatus of the present invention has the advantages of simple structure, easy assemble and setup, high precision assembly and low cost, as well as the capability to perform optimal calibration of the relative position of the focus object lens and the light source of each individual finite conjugate optical system.
