Virtual Sensor Design

Sabine Süsstrunk, Roberto Costantini

We present a virtual digital camera sensor, whose aim is to simulate a real (physical) image capturing sensor.To accomplish this task, the virtual sensor operates in two steps. First, it accepts a physical description of agiven scene and simulates the enti ...

A CMOS 3D camera with millimetric depth resolution

Edoardo Charbon, Pierre-André Besse, Cristiano Niclass, Alexis Rochas

A 3D imager is presented capable of capturing the depth map of an arbitrary scene. Depth is measured by computing the time-of-flight of a ray of light as it leaves the source and is reflected by the objects in the scene. The round-trip time is converted to ...

Vehicle tracking using acoustic and video sensors

Volkan Cevher

In target tracking, fusing multi-modal sensor data under a power-performance trade-off is becoming increasingly important. Proper fusion of multiple modalities can help in achieving better tracking performance while decreasing the total power consumption. ...

First fully integrated 2-D array of single-photon detectors in standard CMOS technology

Theo Lasser, Radivoje Popovic, Alexis Rochas

A two-dimensional (2-D) array (4 by 8) of single-photon avalanche diodes integrated in an industrial complementary metal-oxide-semiconductor (CMOS) process is presented. Each pixel combines a photodiode biased above its breakdown voltage in the so-called G ...
