Methods and systems for a microscope system are provided. In one example, a method for image-based detection of the optical orientation for the microscope system includes acquiring a multitude of contrast samples of an object's field of view, determining a contrast distribution for a multitude of subdivided sub-areas of the field of view based on the multitude of contrast samples, and generating an angular deviation value based on a focus position derived from the contrast distribution for each of the multitude of subdivided sub-areas. In another example, the method further includes adjusting the microscope system based on the angular deviation value.

The present application provides a thermosetting liquid crystal composition having photo-orientation, which contains: a side chain type liquid crystal polymer (A) having a liquid crystal structural unit having a liquid crystal portion in a side chain and a non-liquid crystal structural unit having an alkylene group in a side chain; a copolymer (B) having a photo-orientation structural unit having a photo-orientation group in a side chain and a thermal crosslinking structural unit having a thermal crosslinking group in a side chain, and the photo-orientation structural unit not having a linear alkylene group between the photo-orientation group and a monomer unit; and a thermal crosslinking agent (C) bonded to the thermal crosslinking group of the thermal crosslinking structural unit.

The application provides a preparation method of a liquid crystal polarization holographic device, and the method comprises the step of forming a liquid crystal film on a substrate by vacuum evaporation. The step of vacuum evaporation comprises: liquefying and atomizing an evaporation material, then gasifying the evaporation material to obtain an evaporation material mixed gas; introducing the evaporation material mixed gas into a film plating cavity, so that the evaporation material mixed gas condenses on the substrate to form a liquid crystal film, and then irradiating the liquid crystal film with ultraviolet light for curing. The application adopts vacuum film plating, and the method does not need a solvent, can form a liquid crystal polarization holographic device based on optical orientation with a multi-layer structure and a continuous gradient structure, and eliminates the crosstalk problem between the multi-layer liquid crystal films.
