Abstract

We present a 720 192dToF sensor with a 2,880-channel modular survival histogram TDC (shTDC) array. The shTDC supports non-destructive accumulation while concentrating depth on active bins, reducing memory by 75% with precision comparable to one-step hTDC. Modular hTDCs enable multi-range and multi-resolution imaging to 69.6 m, while double histogram sampling cancels pixel-to-shTDC offsets. The prototype achieves 0.13% precision and 0.12% accuracy.
