    Abstract: A handheld wand comprises a probe at a distal end of the elongate handheld wand. The probe includes a light projector and a light field camera. The light projector includes a light source and a pattern generator configured to generate a light pattern. The light field camera includes a light field camera sensor, the light field camera sensor comprising an image sensor comprising an array of sensor pixels, and an array of micro-lenses disposed in front of the image sensor such that each micro-lens is disposed over a sub-array of the array of sensor pixels.

    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.
