Multi-tap macro-pixel based compressive ultra-high-speed CMOS image sensor

Abstract A burst-mode ultra-high-speed (UHS) CMOS image sensor based on a macro-pixel structure and multi-tap ultra-fast lateral electric field charge modulators (LEFMs) is proposed. This scheme has advantages such as a high frame rate determined only by the in-pixel charge transfer speed and image compression in the charge domain. In previous work, we developed a UHS CMOS image sensor based on multi-aperture optics. To improve the applicability and usability, the proposed method is used with ordinary single-aperture lenses. A prototype image sensor composed of an array of 2x2 subpixels each was implemented as a four-tap LEFM pixel was developed. It was confirmed that the shutter controller operated at 560MHz and time-resolved imaging was performed at 113M frames per second.
