    摘要: A manufacturing method and system are disclosed for illuminating a target. A light controller has a plurality of pixels, and light is projected from at least a first light source to the light controller, wherein the light from the first light source is incident on the light controller at a first angle. The pixels are controlled to establish illumination characteristics for first and second optical paths between the light controller and the target.

    摘要: An optical system for computing a height of a target on a surface includes a light projector for projecting light. The light passes through a patterned reticle and a projector lens so as to illuminate the target with an image of the pattern. The light is projected telecentrically between the reticle and the projector lens, and a camera is positioned along a receive optical path. The camera receives an image of the target through a receive lens. The target and the pattern move at least three times with respect to each other, and the camera acquires an image of the object at each of at least three positions.

    摘要: A computer implemented software device for estimating background tilt and offset is disclosed to preferably be adaptable to an optical measurement instrument wherein the estimated parameters are resolved to generate a reference plane to be subtracted from a height map of a phase profile. A set of histograms of heights is used to develop a merit function. A two-dimensional high speed iterative search is used to optimize the merit function to generate a reference plane coincident with the spatial tilt of the phase profile. The invention enables real-time measurement of substrate height for preferred use in high-speed image processing operations relating to circuit-board production lines.

    摘要: An automated system includes improved height sensing. In one aspect, a on-head camera performs the dual functions of fiducial imaging and height sensing using an auxiliary off-axis light source and triangulation. In another aspect, an on-head height sensor is positioned to measure height at a location that is not beneath any nozzles. The sensor provides height information at a plurality of locations over the board, and a height map of the board is created. In yet another aspect of the invention, the above features are combined to provide an on-head camera that images fiducials and measures height at a plurality of locations such that a height map is created.
