An overlay metrology system may receive overlay data for in-die overlay targets within various fields on a skew training sample from one or more overlay metrology tools, wherein the in-die overlay targets within the fields have a range programmed overlay offsets, wherein the fields are fabricated with a range of programmed skew offsets. The system may further generate asymmetric target signals for the in-die overlay targets using an asymmetric function providing a value of zero when physical overlay is zero and a sign indicative of a direction of physical overlay. The system may further generate corrected overlay offsets for the in-die overlay targets on the asymmetric target signals, generate self-calibrated overlay offsets for the in-die overlay targets based on the programmed overlay offsets and the corrected overlay offsets, generate a trained overlay recipe, and generate overlay measurements for in-die overlay targets on additional samples using the trained overlay recipe.

A system for characterizing at least one particle from a fluid sample is disclosed. The system includes a filter disposed upstream of an outlet, and a luminaire configured to illuminate the at least one particle at an oblique angle. An imaging device is configured to capture and process images of the illuminated at least one particle as it rests on the filter for characterizing the at least one particle. A system for characterizing at least one particle using bright field illumination is also disclosed. A method for characterizing particulates in a fluid sample using at least one of oblique angle and bright field illumination is also disclosed.

The techniques disclosed herein detect sensor misalignments in a display device by the use of sensors operating under different modalities. In some configurations, a near-to-eye display device can include a number of sensors that can be used to track movement of the device relative to a surrounding environment. The device can utilize multiple sensors operating under multiple modalities. For each sensor, there is a set of intrinsic and extrinsic properties that are calibrated. The device is also configured to determine refined estimations of the intrinsic and extrinsic properties at runtime. The refined estimations of the intrinsic and extrinsic properties can then be used to derive knowledge on how the device has deformed over time. The device can then use the refined estimations of the intrinsic and extrinsic properties and/or any other resulting data that quantifies any deformations of the device to make adjustments to rendered images at runtime.
