TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
High-channel-count, high-precision, and high-throughput time-to-digital converters (TDC) are needed to support detector arrays used in deep-space optical communications (DSOC) link receivers being developed between Earth and deep-space solar-system exploration platforms for human and robotic activities in 2020 and beyond. Compared to current radio-frequency (RF) space communications, DSOC will provide 10- to 100-times more data returns for future advanced instruments, live high-definition video, telepresence, and human exploration beyond cislunar space. To be accepted operationally, the optical link must provide substantially greater data rates/data-return volumes than equivalent mass and power RF systems�and at lower cost per bit. Therefore, to prepare for these deep-space missions, substantial enhancement of the current NASA telecom-link capacity is needed. To satisfy NASA�s DSOC needs, a scalable high-precision (≤ 100 ps), high-throughput (> 100 Gbps) high-channel-count (≥ 256) time-to-digital advanced processor (HiTAP) architecture will be developed for use in single-photon-counting free-space optical communications systems and test beds. In Phase II, two fully functional systems integrating custom hardware, firmware, and software will be designed, fabricated, tested, and delivered to NASA.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
HiTAP will enable deep-space optical communications. NASA�s Space Communications and Navigation program office identified optical communications as an important technology for NASA missions, enabling enhanced volume and quality of data to be returned from the farthest reaches of space in preparation for future human deep-space exploration missions. Although several missions have validated optical communications from low-Earth and geostationary orbit, the unique challenges of deep-space optical links still require separate risk-retiring technology demonstrations before implementing inner-orbit communication. Many other NASA applications benefit from the innovation, such as reading out individual pixels of APD arrays, including single-photon avalanche-photodiode detectors and sensor signal-processing nodes. This makes it useful to NASA in systems for applications like LADAR autonomous navigation, docking and landing, space-based laser altimetry for studying the surface height of Earth and other planets from orbit, LIDAR instruments for atmospheric sciences, large-scale surveying / surveillance, bathymetry, and forestry.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
This innovation satisfies the general need for multichannel data processors supporting wideband (GBPS‐class) free-space optical-link FPAs and instruments requiring high-throughput time-of-flight instruments. The proposed innovation also has applications in these fields: free-space optical communications; 3D time-of-flight LADAR and LIDAR mapping systems; positron-emission tomography (PET) imaging in nuclear medicine; single-photon-emission computed tomography (SPECT) imaging in nuclear medicine; time-correlated single-photon-counting and fluorescence lifetime imaging microscopy in life sciences; collision avoidance, imaging, and adaptive cruise control in automotive applications; and data centers for high-throughput real-time data transfer and processing.
