Disclosed is a head-up display device for a vehicle including at least one light source, a liquid crystal display, and at least one polarization converter disposed between the light source and the liquid crystal display and configured to convert unpolarized light generated by the light source into single linearly polarized light and to provide the single linearly polarized light to the liquid crystal display.

Head-up display device for vehicle

The present invention relates to an optical head for revealing near field through beams irradiated from a light source of a far field optical system, the optical head including: a flexible substrate made of a soft material and adapted to allow the optical head to be brought into close contact with a measured object and attached thereto even if the measured object has a curved or flat surface; and a near-field revelation part located between the measured object and the flexible substrate in such a manner as to have one side brought into contact with the flexible substrate and the other side detachably attached to the measured object and adapted to reveal the near field through the beams irradiated from the light source.

Dynamic optical head and imaging device using flexible nano film optical structure

A near field optical imaging device includes: a light source for radiating light of a far field optical system; and an optical head including thin film layer for formation of dynamic optical nano apertures, combined with a measured object in one piece to generate a near field by a beam radiated from the light source, in which the measured object can be scanned in a depth direction by adjusting a depth of the near field, and the depth of the near field is adjusted by modifying a shape of an opening of the thin film layer for formation of dynamic optical nano apertures by adjusting an amount of the light radiated from the light source.
