A new dual-microcomb method enables chip-scale devices to measure distances with nanometer accuracy, paving the way for advances in nanotechnology and photonics. (Nanowerk News) Optical frequency ...

As a choice for an entry level project into image and data processing, one of the possible options was to use camera devices to measure distance of surfaces. As a trial project to be carried out on a ...

This project primarily consists of four units: Microchip Technology’s SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact ...

Detection distance is an important and common auxiliary variable measured during avian point count surveys. Distance data are used to determine the area sampled and to model the detection process ...

Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...

A satellite positioning system that receives a radio wave from an artificial satellite and specifies a position on the ground,GPSIf you are using it, you may find that sometimes errors occur. Also, ...

Sometimes astronomy is like real estate — what’s important is location, location, location. Astronomers have resolved a major problem in their understanding of a class of stars that undergo regular ...
