Bio-inspired Stereo Vision System with Silicon Retina Imagers

This paper presents a silicon retina-based stereo vision system, which is used for a pre-crash warning application for side impacts. We use silicon retina imagers for this task, because the advantages of the camera, derived from the human vision system, are high temporal resolution up to 1ms and the handling of various lighting conditions with a dynamic range of ∼120dB. A silicon retina deliver...

Machine vision for defect detection on silicon wafers

For several real-world problems, the mathematical methods of signal and image processing are most successful when they also incorporate the insight offered by the physics of the problem. Imaging systems are a particularly fertile ground for problems in this class because they deal specifically with the capture of physical scenes and with the reproduction of images on physical devices. Solutions...

Effect of Silicon Nanowire on Crystalline Silicon Solar Cell Characteristics

Nanowires (NWs) are recently used in several sensor or actuator devices to improve their ordered characteristics. Silicon nanowire (Si NW) is one of the most attractive one-dimensional nanostructures semiconductors because of its unique electrical and optical properties. In this paper, silicon nanowire (Si NW), is synthesized and characterized for application in photovoltaic device. Si NWs are ...
