Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.

Only a tiny sliver of the Universe’s light can be seen by human eyes. But today we’re catching glimpses of the invisible ...

trace gas sensor is demonstrated here for the first time combining laboratory calibration with real-world sample analysis in field. A calibration range of 100–1000 ppb analyte/N 2 was developed and ...

A real-time object detection and distance measurement system using the HC-SR04 ultrasonic sensor, developed in Embedded C for the LPC1768 microcontroller using Keil μVision.

A Volvo EX90's lidar sensor was caught on video damaging a ... It works by firing pulses of laser light (often in the near-infrared spectrum) and measuring the time it takes for them to bounce ...

Abstract: We describe a method for accurately estimating the topology of sensor networks from time-series data collected from infrared proximity sensors. Our method is a hybrid combining two different ...

Among all possible solutions, onboard sensors have several advantages, in terms of ease of deployment and calibration, and absence of occlusions. In this paper, we present a prototype of a distributed ...
