    Abstract: The present disclosure provides computing device implemented methods, apparatuses, and computing device readable media for confocal imaging using astigmatism. Confocal imaging can include receiving an image of a portion of an object captured by a confocal imaging device having a particular astigmatic character, determining an image pattern associated with the image, and determining a distance between a focus plane of the confocal imaging device and the portion of the object based, at least in part, on information regarding the image pattern. Confocal imaging can also include receiving data representing an image pattern associated with an image of an object captured by a confocal imaging device having a particular astigmatic character and having an image sensor with a plurality of pixels, and determining a positional relationship between the object and a focus plane of the confocal imaging device based on a distribution of the diffraction pattern over a portion of the plurality of pixels.

    Abstract: An apparatus is described for measuring surface topography of a three-dimensional structure. In many embodiments, the apparatus is configured to focus each of a plurality of light beams to a respective fixed focal position relative to the apparatus. The apparatus measures a characteristic of each of a plurality of returned light beams that are generated by illuminating the three-dimensional structure with the light beams. The characteristic is measured for a plurality of different positions and/or orientations between the apparatus and the three-dimensional structure. Surface topography of the three-dimensional structure is determined based at least in part on the measured characteristic of the returned light beams for the plurality of different positions and/or orientations between the apparatus and the three-dimensional structure.
