Teledyne offers a complete range of Time Delay Integration (TDI) image sensor solutions from Earth observation land scanning using traditional CCD technologies through to next generation remote sensing CMOS TDI platform product families and hyperspectral and multispectral solutions.
Teledyne offers standard and customized packaging options and designs optimized for radiation hardness and extreme environments enabling cost-effective small satellite optical payload design.
Whilst improvement in CMOS Image Sensors (CIS) for space applications are allowing this technology to expand into the space domain TDI applications until now have been a challenge for CMOS due to its intrinsic operating mode. Charges are directly converted into voltage at the output of each pixel. In order to overcome this limitation, the standard approach consists of moving to digital summation whereby voltages are converted into digital values which are summed up as the scene is moving through the TDI array. Teledyne Imaging, building on its unmatched heritage in CCD TDI designs, offers charge-domain CMOS TDI, combining the noiseless summation advantages of CCD structures with the massively parallel on-chip analog-to-digital conversion of CMOS. The result: devices with the sensitivity and dynamic range of CCD with the speed and throughput of CMOS...built with our decades of experience in space-qualified designs.
