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.

At least one polarization filter is oriented vertically, and at least one polarization filter is oriented horizontally in relation to the usual position of the element.

Measured image values measured according to this method without a polarization filter are converted to measured image values measured with a polarization filter.

The light detecting arrangement (4) is equipped with a polarization filter (3).

At least two of said areas are associated with a luminous polarization filter.

The optical layer construction (1) can be designed as a circular polarization filter or alternatively as a linear polarization filter (1') and as a lambda quarter delay layer (1'').

Blocking is effected using electro-optic liquid crystal shutters each of which has a front linear polarizing filter with a defined axis of polarization.

Light-absorbing diaphragms are arranged under the tops of said films.

The optical filter has a configuration in which a polarization filter layer and a spectral filter layer are laminated in light transmission direction.

The effect filter (121) which gives some effect to an image pricked up by a camera is, for example, a colored filter or a polarizing filter.

The non-orthogonal polarizing filter reflects a recycled image back to the front surface.

A polarization filter (2) or spectral filter (3) is used for the selection of the radiation to be amplified.

̶ You mean I know how to use a polarizing filter.

A patterned polarization filter is preferably located in the optical path of the emitted light to improve the polarization ratio of the emitted light.

A polarization filter (8) is disposed on the front side of the liquid crystal cell (1-7), the path polarization direction thereof being parallel to the path-polarization direction of the polarizing converting film (9).
