Simulation results indicated that this method could generate a temperature gradient up to 40 °C between the two polymer sides, leading to rapid folding. The proposed method suitably folded components remotely, particularly for optically blocked or wrapped materials. Other applications of size ...
The rays from the object reach the FZP array through the lenses and BS. Then, the rays reflected from the FZP passes through the BS and the camera lens to create an image on a CCD imager. The lens array was used to capture images from different parts of the object at various angles ...
array of micro-lenses on the array of LEDs, wherein a width of each micro-lens of the array of micro-lenses may be greater than a width of each LED of the array of LEDs. In some embodiments, the light source may include dielectric material regions surrounding each LED of the array of...

6c). A finite element simulation was performed to show the electric field distribution in a cavity as a reference (Fig. 6c, more details in Supplementary Note 5). Fig. 6: Free-space coupling map of fundamental and higher-order modes. Data were acquired using a ×20 objective lens (NA...
We developed a novel micro-droplet array system, which is based on the distinct three dimensional mesh screen structure and sintering and oxidation induced thermal-fluid performance. Mesh screen was sintered on a copper substrate by bonding the two compo
