An optical imaging film includes: a focusing layer, having two or more focusing structures; and a graphic layer, having two or more sub-graphics, and at least part of the sub-graphics are configured as a partial pattern of a preset graphic. The focusing layer is adapted to the graphic layer, and the focusing structures are provided corresponding to the sub-graphics, such that the optical imaging film presents an image of the preset graphic with a magnifying effect. The graphic layer of the optical imaging film includes a plurality of sub-graphics, and each of the plurality of the sub-graphics interacts with the corresponding focusing structure to form an image with a magnifying effect. Therefore, the sub-graphic is relatively large, thereby increasing the size of the images. That is, the optical imaging film can increase the magnification of the preset graphic.

The present invention proposes a method for producing an authenticable moiré shape that simultaneously moves and shows a beating effect. The method relies on a combination of the 1D or the 2D moiré and the level line moiré. When tilting a compound showing such a moiré, the moiré shape moves, its intensity levels change significantly but its shape remains the same and is recognizable. Embodiments comprise a base layer made of patterned metallic tiny shapes and a revealing layer made of a 1D array of cylindrical lenslets or of a 2D array of spherical or aspherical lenslets.

The technology disclosed relates to structured illumination microscopy (SIM). In particular, the technology disclosed relates to capturing and processing, in real time, numerous image tiles across a large image plane, dividing them into subtiles, efficiently processing the subtiles, and producing enhanced resolution images from the subtiles. The enhanced resolution images can be combined into enhanced images and can be used in subsequent analysis steps. The technology disclosed includes logic to reduce computing resources required to produce an enhanced resolution image from structured illumination of a target. A method is described for producing an enhanced resolution image from images of a target captured under structured illumination. This method applies one or more transformations to non-redundant data and then recovers redundant data from the non-redundant data after the transformations.

Methods and systems for imaging a sample using fluorescence microscopy. High resolution lenses can be used for light sheet microscopy by tilting the excitation beam relative to the imaging optical axis. The excitation beam can be tilted using mirrors, instead of lenses, to generate the tilted illumination sheet. In some examples, a light path starts at a top downward-facing cone of light as it emerges from an optic fiber; a first off-axis parabolic mirror collimates in the x-axis, while a second off-axis parabolic mirror collimates in the y-axis, followed by the photomask to create four primary light sheets, which are then focused by a third off-axis parabolic mirror. As the four primary light sheets converge they create an interference pattern at an objective lens.

A metrology system and metrology methods are disclosed. The metrology system includes an illumination sub-system, a collection sub-system, a detector, and a controller. The controller is configured to receive an image of an overlay target on a sample, determine an apparent overlay between two working zones along a measurement direction based on the image, and calculate an overlay between the two sample layers by dividing the apparent overlay by a Moiré gain to compensate for Moiré interference.
