The high level of accumulated expertise by ULIS and CEA/LETI on uncooled microbolometers made from an amorphous silicon layer enables ULIS to develop 384 x 288 (1⁄4 VGA) IRFPA format with 25 μm pixel-pitch designed for low end application. This detector has kept all the innovations developed on the full TV format ROIC (detector configuration by serial link, low power consumption or wide electri...

This paper presents a resolution-reconfigurable wide-range resistive sensor readout interface for wireless multi-gas monitoring applications that displays results on a smartphone. Three types of sensing resolutions were selected to minimize processing power consumption, and a dual-mode front-end structure was proposed to support the detection of a variety of hazardous gases with wide range of c...

ABSTRACT Despite regulators’ allegations that digital technology giants misuse their market power to earn abnormal profits, there is a dearth of systematic work on (1) whether digital-tech firms in general, and tech particular, excess profits or (2) profitability, if any, due power. We use two alternative measures economic profitability addition accounting rate return (ARR): internal (IRR), whi...

Basing on the temperature dependent elastic model of underfill and the Anand’s viscoplastic model of indium bumps, A three-dimension finite element model is developed to simulate the structural stress and its distribution in 32×32 InSb infrared focal plane arrays integrated with microlens arrays. To learn the stress and its distribution for large format array in a short time, a small 8×8 InSb I...

The reticulated InSb pixel array was successfully employed in the design of large format InSb infrared focal plane arrays (IRFPAs) detector, to remove the thermal strain accumulated in InSb IRFPAs with the thermal shock test. In order to explore the deformation rules in the InSb IRFPAs with reticulated InSb pixel array, in light of the proposed equivalent modeling, a three-dimensional modeling ...

Imaging in the infrared wavelength range has been fundamental in scientific, military and surveillance applications. Currently, it is a crucial enabler of new industries such as autonomous mobility (for obstacle detection), augmented reality (for eye tracking) and biometrics. Ubiquitous deployment of infrared cameras (on a scale similar to visible cameras) is however prevented by high manufactu...
