LiDAR Technologies and Systems

2019-07-10
LiDAR is one of many active sensor technologies that uses electromagnetic radiation. Operating in the optical and infrared wavelengths, it is similar to more-familiar passive EO/IR sensor technology. It is also similar to radar in that it uses reflected electromagnetic radiation emitted by the sensor. LiDAR is commonly used for making high-resolution maps and has applications in geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping, and laser altimetry. It is also being used for control and navigation of some autonomous cars. The first part of LiDAR Technologies and Systems introduces LiDAR and its history, and then covers the LiDAR range equation and the link budget (how much signal a LiDAR must emit in order to get a certain number of reflected photons back), as well as the rich phenomenology of LiDAR, which results in a diverse array of LiDAR types.

Hundred

2013-01-01
Writing in 1901, the futurist H. G. Wells predicted not only the decline of railways but the rise of the “motor truck” – a term unfamiliar to most readers at that time. Wells foresaw “large carrier companies” with fleets of horseless vehicles “to carry goods in bulk or parcels.” At the turn of the 20th century, colossal railroad companies ruled long-distance “land locomotion.” And the prospect of commercial life without draft horses seemed about as likely as Martians invading Earth – a story Wells had published four years earlier. But only one year later, ironically in a horse barn near a Chicago tannery, an ex-bicycle maker named Magnus Hendrickson began assembling Wells’ vision. This would become a decades-long undertaking to divine, design, build, continuously improve and ultimately perfect what makes a truck a truck – not simply a bigger car. Along the way, Magnus and his sons founded The Hendrickson Motor Truck Company, which in 2013 celebrated 100 continuous years of operations.
