Ultra-high speed imaging at megaframes per second with a megapixel CMOS image sensor.

11 November 2013

Abstract

Thanks to the continuous improvement in CMOS sensor design, pixel rates around or in excess of 10 Gpixel/sec are currently achieved by a few sensors (Figure 1). Recently a new approach [1], based on a bank of capacitive memories located on‐chip on the side of the pixel array, has gone beyond the limit of Tpixel/sec in burst mode. In this paper, we present a highly scalable approach that also achieves pixel rate in excess of 1012 pixel/sec.

Designed for generic use in ultra‐high speed imaging, this sensor, called Kirana [2], works by storing 180 consecutive frames in each pixel at a speed of up to 5 Mframe/sec. This approach is similar to that found in some existing CCD sensors [3][4]. Here we will present the imager design and its performance, while technical details of the CCD‐in‐CMOS technology are more thoroughly discussed in [5].
