Design and Realization of a Lensless CMOS Image Sensor for Light Source Tracking

Localization of a light source in the space requires capturing its light intensity and angle information. However, conventional CMOS image sensors can only capture light intensity and wavelength. These sensors need to be augmented with an optical extension such as an aperture or a lens in order to capture the angle information. The use of...

Time-of-Flight 3D Imaging based on a SPAD-TDC Pixel Array in Standard 65 nm CMOS Technology

The interest in high performance three-dimensional (3D) imaging has grown in recent years due to immense demand in engineering, science, medicine and entertainment domains. The driving goals of state-of-the-art 3D imagers are high sensitivity to light and fine depth resolution at long range. Furthermore, high level of integration is desirable to...
