The phase modulation device includes a phase modulation element which includes a plurality of electrodes, and modulates the phase of the light flux in accordance with a voltage applied to each electrode, and a control circuit which controls the voltage to be applied to each electrode. The control circuit controls the voltage to be applied to each electrode in such a manner that the light flux is imparted with a phase modulation amount in accordance with a phase modulation profile having a polarity opposite to the polarity of a phase distribution to be determined according to a relational equation representing a relationship between a numerical aperture of the objective lens and a ratio between third-order spherical aberration and fifth-order spherical aberration.

摘要： A polarization conversion element includes a phase reversal element and a polarization plane rotation element including a liquid crystal layer. The liquid crystal layer has a plurality of regions disposed along circumferential direction with the intersection point of the polarization plane rotation element and the optical axis as the center with alignment directions different from each other. When electric voltage in accordance with the wavelength of linear polarization incident on the polarization plane rotation element is applied, each region rotates the polarization plane of the polarization component transmitted by each region, and thereby converts linear polarization to radial polarization. The phase reversal element reverses, among the first and the second annular portions alternately disposed along the radial direction with the optical axis as the center, the phase of light incident on the first annular portion relative to the phase of light incident on the second annular portion.

摘要： The present invention is directed to the provision of a liquid crystal device constructed by sealing a liquid crystal material between substrates, wherein provisions are made to prevent reflections at the sealing, thereby achieving excellent transparency. The liquid crystal device includes a first substrate disposed on a viewing side, a second substrate disposed opposite the first substrate, a sealing member disposed between the first substrate and the second substrate, a liquid crystal layer provided between the first substrate and the second substrate and sealed by the sealing member, and a muslin structure or moth-eye structure placed between the first substrate and the sealing member. The muslin structure or moth-eye structure serves to form a smooth refractive index gradient between the sealing member and the first transparent substrate, thereby enhancing the transparency of the liquid crystal device.
