Here, we present a logarithmic CMOS imager for emissivity-compensated thermography, having thermally-stable and optimized inorganic multilayer integrated filters and a pixel cell containing a subthreshold load transistor with optimized device layout, providing VGA resolution, 40fps, a measuring temperature range of 600 degC to 3000 degC, and a temperature resolution of ~5 degC.
An image-based technique with high measurement rate has been proposed to measure the distance between two moving vehicles. By combining several near-infrared (NIR) LED markers mounted on the forward vehicle with an NIR-filtered CMOS camera mounted on the backward vehicle, one can clearly recognize the marker shape and positions without any adjusting the focus lens of camera, and hence he can extremely...
