Abstract:
A method involves receiving a test image of at least a portion of a test object which includes a test moiré pattern generated by superposing one or more reference gratings on one or more subject gratings. The method further involves analyzing one or more test beat lines in the test moiré pattern and calculating one or more test values based on the analysis of the one or more test beat lines. The one or more test values are a function of one or more rotational angles corresponding to the one or more subject gratings and a shape of at least the portion of the test object. The method also involves calculating one or more angular errors of the one or more subject gratings based on the one or more test values and one or more template values and sending a notification based on the one or more angular errors.
Abstract:
An optical imaging system includes a birefringent element, a light modulating element, and a polarizer element. The birefringent element is configured for decomposing un-polarized light into first linear polarized light and second linear polarized light under different refractive indexes to respectively form a first focal length and a second focal length in the optical imaging system. The light modulating element is configured for modulating a state of polarization of the first and second linear polarized light in response to control signals. The polarizer element is configured for filtering out one of the modulated first and second linear polarized light for creating a single image.
Abstract:
An image capture device includes an electro-optics arrangement having an arrangement of polarizers, polarization sensitive optical elements, and polarization modulating elements. First and second polarization sensitive optical elements are provided having an edge displaced relative to a plane normal to an optical axis of the electro-optics arrangement. A control system coupled to the electro-optics arrangement controls the application of voltages to the polarization modulating elements to control the polarization rotation of the light input to the polarization sensitive optical elements, such that the optical path length of the polarization sensitive optical elements is changed to provide for capture of the object images at each of the different focal planes. The first and second polarization sensitive optical elements generate lateral image shifts between respective object images captured at the different focal planes responsive to the polarization rotation of the light input thereto.
Abstract:
A multi-resolution lens system includes a relay lens configured to be directed toward a field-of-view (FOV) and receive a first plurality of image photons emanating from the FOV, a high-resolution lens positioned to receive a second plurality of image photons from the FOV and to pass the second plurality of image photons toward the relay lens, and a shutter device positioned to receive over an area thereof the image photons of the FOV that pass through the relay lens, and simultaneously receive overlaid on a portion of the area thereof the image photons from the portion of the FOV that pass through the high-resolution lens and toward the relay lens.
