An image pickup device is put on the side of the transparent member the same as that of a light source and takes reflected light including regular reflection from an interface between an adhered object on the other surface of the transparent member and air. Assuming an incident angle of the emitted light on the transparent member when the light reflected in regular reflection by the other surface of the transparent member is incident on the image pickup lens being θ s, an incident angle of a typical light beam of the emitted light falls within θ s - 30 deg through θ s and an incident angle of a main element of the emitted light is less than θ s.

摘要： An optical element transmits incident light having a particular polarization direction mainly by 0-order transmission and diffracts incident light having a perpendicular polarization direction. The optical element includes a periodic structure having a period equal to or greater than the wavelength of the incident light. The periodic structure includes first and second subwavelength concave-convex structures formed perpendicularly adjacent to each other in each period of the periodic structure.

摘要： An optical pickup device is disclosed. In the optical pickup device, S-polarized light is input to a polarization filter from a DVD light source or a CD light source. Since the polarization filter transmits through the S- polarized light and diffracts P-polarized light, the S-polarized light is transmitted through the polarization filter. The S-polarized light is converted into three beams by being diffracted by a diffraction element. The three beams reflected at a polarization beam splitter are converted into circularly polarized light by a 1/4 wavelength plate via a collimate lens, and the circularly polarized light is condensed on an optical recording medium via an objective lens. Light reflected from the optical recording medium is converted into linear P-polarized light by the 1/4 wavelength plate via the objective lens. Substantially almost all P-polarized light is transmitted through the polarization beam splitter. A slight amount of the returning light travels to the side of the light source.
摘要翻译：公开了一种光学拾取装置。在光拾取装置中，S偏振光从DVD光源或CD光源输入到偏振滤光器。由于偏振滤波器透过S偏振光并衍射P偏振光，所以S偏振光透射通过偏振滤光器。通过被衍射元件衍射，将S偏振光转换成三个光束。在偏振分束器处反射的三束光经由准直透镜被1/4波长板转换为圆偏振光，圆偏振光经由物镜在光记录媒体上聚光。从光记录介质反射的光经由物镜被1/4波长板转换为线性P偏振光。基本上几乎所有的P偏振光透射通过偏振分束器。少量的返回光行进到光源的一侧。

摘要： A disclosed optical pickup includes an aberration correction unit with a phase shifter surface. On the phase shifter surface, rectangular or staircase- like steps are formed in a concentric manner around an optical axial center, in certain regions where a light beam passes through. The steps have different heights in the optical axial direction. A light beam having a wavelength of 405 nm is directly transmitted through the steps so that a phase difference is applied for correcting spherical aberration that occurs on a first optical recording medium. A light beam that passes through an annular region without any steps is focused on a second optical recording medium. A light beam that passes through an outside region is focused by an object lens on the second optical recording medium, and is not focused on the first optical recording medium.
