A new imaging sensor with high resolution independent of the image sensorpsilas pixel size is presented. This sensor combines an integrated nanohole patterned in the first metal layer within each pixel and it can be fabricated in any standard submicron CMOS process. The final high resolution image requires a relative scanning motion between the sensor and the object under test; this relative motion...
We have implemented a new high resolution imaging system independent of the image sensorpsilas pixel size. This super-resolution is achieved by integrating a nano-aperture patterned in the first metal layer within the pixel using a standard CMOS process. The image sensorpsilas focal plane is scanned with a sub-micron step to obtain the super-resolution image. To experimentally verify the operation...
This paper presents a low cost but high resolution retinal image acquisition system of the human eye. The images acquired by a CMOS image sensor are communicated through the Universal Serial Bus (USB) interface to a personal computer for viewing and further processing. The image acquisition time was estimated to be 2.5 seconds. This system can also be used in telemedicine applications.
