This paper describes the design and characterization of a 16x16-pixel image sensor, fabricated in a 0.35 um, 3.3 V CMOS technology for real time three dimensional measurements based on multiple-pulse indirect Time-of-Flight technique. Owing to an innovative fully differential pixel (FDP) architecture, which allows for the detection of very short and low intensity light pulses, the sensor array provides a range map from 2m to 9m with a precision of ¡Ó4.0% at 2m and ¡Ó1.7% at 9m. The pixel power consumption is 100 ƒÝW, whereas the overall power consumption of the chip is 47 mW in real time operation (30 fps).

This paper describes the design and characterization of a 16x16-pixel image sensor, fabricated in a 0.35 um, 3.3 V CMOS technology for real time three dimensional measurements based on multiple-pulse indirect Time-of-Flight technique. Owing to an innovative fully differential pixel (FDP) architecture, which allows for the detection of very short and low intensity light pulses, the sensor array provides a range map from 2m to 9m with a precision of ¡Ó4.0% at 2m and ¡Ó1.7% at 9m. The pixel power consumption is 100 ƒÝW, whereas the overall power consumption of the chip is 47 mW in real time operation (30 fps).File in questo prodotto:
