It’s worth noting that a linear polarizer differs from a circular polarizer as it lacks an additional quarter-wave plane. The quarter-wave plane is added to circularly polarize linearly polarized light, making it compatible with auto-focus and exposure functions. However, using a linear polarizer can affect in-camera auto-focus and exposure accuracy since it filters light differently. When light becomes circularly polarized, it enables the use of these functions.

Tiffen 4 x 5.65″ Linear Polarizer Filter effectively diminishes reflections and glare by filtering polarized light resulting from non-metallic surface reflections. When sunlight reflects off air molecules, it becomes partially polarized, creating a hazy effect. A linear polarizer aligns and filters this polarized light perpendicular to the reflected light, leading to the absorption of a significant portion of this light. This leads to a noticeable reduction in glare and reflections from non-metallic surfaces and enhances the saturation of skies and foliage.

Feature papers represent the most advanced research with significant potential for high impact in the field. A Feature Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for future research directions and describes possible research applications.

Abstract: Hyperspectral (HS) images usually have high spectral resolution and low spatial resolution (LSR). However, multispectral (MS) images have high spatial resolution (HSR) and low spectral resolution. HS–MS image fusion technology can combine both advantages, which is beneficial for accurate feature classification. Nevertheless, heterogeneous sensors always have temporal differences between LSR-HS and HSR-MS images in the real cases, which means that the classical fusion methods cannot get effective results. For this problem, we present a fusion method via spectral unmixing and image mask. Considering the difference between the two images, we firstly extracted the endmembers and their corresponding positions from the invariant regions of LSR-HS images. Then we can get the endmembers of HSR-MS images based on the theory that HSR-MS images and LSR-HS images are the spectral and spatial degradation from HSR-HS images, respectively. The fusion image is obtained by two result matrices. Series experimental results on simulated and real datasets substantiated the effectiveness of our method both quantitatively and visually.

We recommend using the Tiffen 4 x 5.65″ Linear Polarizer filter when you’re not relying on in-camera exposure metering or autofocus. This non-coated filter offers an average light transmission of around 40%.

Tiffen filters are manufactured using ColorCore technology, a precise process involving the lamination of the filter substrate between two optical glass pieces, ground flat with exceptional precision (1/10,000th of an inch tolerance).
