Abstract: An identification medium, in which a pattern is clearly altered in observation through a right-handed circularly polarizing filter and observation through a left-handed circularly polarizing filter, is provided. The identification medium is formed by laminating a cholesteric liquid crystal layer, a ?/4 plate, and a linearly polarizing filter layer, in that order, from an observing side. The cholesteric liquid crystal layer is formed with a hologram and selectively reflects light. In an observation through a circularly polarizing filter that transmits the light reflected at the cholesteric liquid crystal layer, light reflected at a pattern printed layer is not perceived due to the function of a circularly polarizing layer. Images are clearly altered by switching a right-handed and a left-handed circularly polarizing filter.

Abstract: An identification medium is provided in which latent image having plural colors can be observed even when the identification medium is spaced away from a polarization filter. A cholesteric liquid crystal layer is provided as a specific polarization light reflection layer which reflects light having a specific polarized condition. An optical anisotropic layer having an optical anisotropy is provided at an upper position overlapping with the specific polarization light reflection layer. An image A fanned by an area having an optical anisotropy different from that of surroundings is formed at the optical anisotropic layer. When the identification medium is directly viewed, the influence of the optical anisotropy cannot be seen. When the identification medium is observed via a circular polarization filter, the image can be seen to have a specific color by the influence of the optical anisotropy.

Abstract: This invention provides an optical lens system in order from an object side to an image side comprising: a first lens element having a convex object-side surface; a negative second lens element having a concave object-side surface and a convex image-side surface; a positive third lens element having a convex object-side surface and a convex image-side surface; a plastic negative fourth lens element having a concave object-side surface and a convex image-side surface, with both the object-side and image-side surfaces thereof being aspheric. By such arrangement, the incident angle of off-axis light projected onto the sensor can be suppressed for improving the sensitivity of the sensor effectively. Also, a sufficient back focal length can be retained for disposing other optical elements (e.g., an IR-pass filter), and thereby the system can be more suitable for the infrared aspect of optical imaging systems.
