Moiré & False Colour

in the final image A third example of the difference in sharpness between the D800 and D800E The increased resolution of the D800E is slight An example of moiré and false colour can be seen in the kimono fabric in the image that was captured with the D800E Another example of the difference in sharpness between the D800 and D800E The increased

Measuring Die Tilt Using Shadow Moiré Optical Measurements

the final result is shown in Figure 10 Figure 10 Die Warpage Relative to Substrate Plane In this case the level of warpage of the die does raise interesting questions about how die tilt is calculated by other techniques If we only consider the four corners of the die, warpage can affect the measured angle First, die

Comparison of Advanced Package Warpage Measurement Metrologies

Shadow moire requires sample preparation where BGAs were removed and coated a layer of high temperature resistance white paint • Sample Preparation • Depending on sample condition, fringe contrast, shiny reflection and protrusion can add noise to the measurement Particular true for shadow moire and DFP technique

CORRELATION OF SOLDER JOINT RELIABILITY OF μPGA SOCKET TO

illustrate the Moire topography of the PCB surface under the emulated temperature profile This is the actual concave surface configuration of PCB under thermal process The PCB warpage is defined as the difference between the maximum to minimum z-axis height of the package along the diagonal line and is presented in units of mil per inch

NTIRE 2020 Challenge on Image Demoireing: Methods and Results

the participants received both moire and moire-free train-ing images of the dataset (2) Validation phase: the par-ticipants had the opportunity to test their solutions on the moire validation images and to receive immediate feedback by uploading their results to the server A validation leader-board was available (3) Final evaluation phase
