High Dynamic Range Uniaxial Force/Torque Sensor Using Metal Foil and Semiconductor Strain Gauge

High dynamic range hybrid pixel sensor

A new readout imaging system with enhanced dynamic range (DR) and low power consumption is presented. The DR is enhanced by using feedback to control the integration time of the sensor. The feedback is implemented within an in-pixel-level ADC. The power consumption is reduced by switching the bias circuit off when it is not needed for the system, this readout circuit is used for a hybrid sensor...

Large Strain Range Dynamic Testing at High and Medium Strain Rates, Using a Common Scale SHPB

A High Dynamic Range CMOS APS Image Sensor

In this paper, a new visible image sensor with 110 dB intrascene dynamic range is reported. The sensor captures four linear response images with different sensitivities simultaneously at 60 frames per second (fps). A real time fusion and dynamic range compression (DRC) algorithm, which is implemented by an FPGA, is also presented. This algorithm can generate a high dynamic range image from the ...

Quantitative Study of High Dynamic Range Image Sensor Architectures

Analysis of dynamic-range (DR) and signal-to-noise-ratio (SNR) for high fidelity, high-dynamic-range (HDR) image sensor architectures is presented. Four architectures are considered: (i) time-to-saturation, (ii) multiplecapture, (iii) asynchronous self-reset with multiple capture, and (iv) synchronous self-reset with residue readout. The analysis takes into account circuit nonidealities such as...

High dynamic range electric field sensor for electromagnetic pulse detection.

We design a high dynamic range electric field sensor based on domain inverted electro-optic (E-O) polymer Y-fed directional coupler for electromagnetic wave detection. This electrode-less, all optical, wideband electrical field sensor is fabricated using standard processing for E-O polymer photonic devices. Experimental results demonstrate effective detection of electric field from 16.7V/m to 7...
