This paper presents an investigation of the responsivity of a time-delay integration (TDI) charge-coupled device that employs anti-blooming clocking and uses a varying number of TDI stages. The influence of charge blooming caused by unused TDI stages

A one-dimensional analytical model of charge transfer in charge-coupled devices, which describes the spatial-temporal behavior of the charge carrier density in a potential well, is presented. The general solution of this model considers the transfer

Single-Photon Avalanche Diode (SPAD)-based ’Light Detection And Ranging’ (LiDAR) systems often use the first photon measurement principle to acquire ranging information. While those systems provide accurate distance measurements, they can easily
A fast and reliable three dimensional monitoring of the environment is indispensable for robotics, automation engineering or autonomous driving. For these applications LiDAR is a key sensor technology. Normally a light source in the near infrared ran

LiDAR is a key sensor technology for future driving. For autonomous vehicles a fast and reliable three dimensional monitoring of the environment is essential for managing a wide variety of common traffic situations. Since these kinds of systems use t
Indirect time-of-flight (TOF) measurement with single-photon avalanche diodes (SPADs) is performed by counting incident photons in several time windows. Since SPADs exhibit dead time not all incident photons can be counted within a given time window.

This communication addresses the range accuracy of SPAD-based time-of-flight (TOF) sensors that employ laser pulse modulation. Two basic approaches are considered: indirect and direct TOF. We investigate confidence intervals and derive formulas for s

High ambient illumination reduces the range and target detection reliability in light-based 3D sensors. Raising the optical power of the artificial illumination source to overcome the influence of high ambient light is often not possible for systems
