Video imaging of single molecule DNA replication

Almost all life is based on DNA being copied or replicated. Now for the first time, scientists have been able to watch the replication of a single DNA molecule, with some surprising findings. For one thing, there is a lot more randomness at work than has been thought.

Linear Fresnel Spectrometer Chip with Gradient Line Grating

NASA's Langley Research Center has built a very small spectrometer by integrating a differential linear Fresnel lens onto an imaging chip. NASA is using the lens/chip in a very small spectrometer that will be mounted on the tires of a rover to analyze soil on the Moon or Mars. The...

Machine Vision System

A number of instruments have been built to obtain range images — a two-dimensional array of numbers that gives the depth of a scene along many directions from a central point in the instrument. Instead of measuring the brightness of many points in a scene, as in a television camera, these instruments measure where each...

Lock-In Imaging System for Detecting Disturbances in Fluid

NASA's Langley Research Center has developed an aircraft-based turbulence and vortex detection system. Turbulence and vortices in the front-flight path are very dangerous for airplanes. Especially when an airplane is approaching the airfield to land, the altitude near the airfield is...

Curved Sensor Improves Image Quality Captured with Digital Cameras

In dark environments, it is often difficult to get a clear, high-quality image. To address this problem, a method was developed for spherically curving the flat image sensors found in digital cameras. The curved sensors could be used to create better cameras for surveillance,...

Algorithm Enables Five-Dimensional Imaging in Living Organisms

Researchers use fluorescent imaging to locate proteins and other molecules in cells and tissues by tagging the molecules with dyes that glow under certain kinds of light — the same principle behind “black light” images. Fluorescent imaging can help scientists and researchers...

Question of the Week : Imaging
Do you see augmented reality as a way of improving design processes?

A report last week concluded that the augmented reality (AR) market is expected to grow from $2.39 billion in 2016 to $61.39 billion by 2023. The research from the Hadapsar, India-based analyst firm MarketsandMarkets cites increasing demand for AR devices and applications in...

Sound-Off: How Do a Vehicle’s Imaging Sensors Filter Out Weather, Crosstalk?

A "Geiger-mode" lidar sensor sends out pulses at a high repetition rate (200 kHz), forming an image on the percent of pulses that return. The technology has been used by vehicle manufacturers to support collision avoidance, adaptive cruise control, and other Advanced...
