| Abstract(in English) | For 3D Imaging laser detection and ranging (LADAR) systems that obtain the real-time 3D range image, the time-of-flight (TOF) method is widely used. We have developed the 3D Imaging LADAR system using analog Read-Out Integrated Circuits (ROIC) array devices to detect TOF and intensity amplitude of received pulse signal from targets. The characteristic variation of array elements causes the dispersion of the LADAR coverage and the range error. This paper presents the 64 linear array ROIC which can suppress the characteristic variation of array elements by using the calibration functions with Digital to analog Converter (DAC). The developed ROIC which fabricated by 0.1811m SiGe-BiCMOS process consists of analog peak detector arrays and high precision time to amplitude converter (TAC) arrays. It is achieved that the measured variation of sensitivity of the peak detector is less than 1 % and the measured characteristic variation of TAC is under 0.3% using calibration with DAC. Installing this ROIC, we realized 256 x 256 pixels range imaging with an on-line frame rate of more than 30 Hz. |
