Current range-gated imaging methods based on triangular or trapezoidal models face significant limitations in terms of the accuracy and precision of three-dimensional (3D) reconstruction. Here, we establish a range-gated 3D super-resolution image reconstruction method based on a Gaussian-range-intensity...
SINTEF and its EU partners developed an imaging system that minimizes the effects of backscatter in turbid environments—conditions that would be impenetrable with a traditional underwater camera.
2) range gated imaging 距离选通成像 1. Compared with traditional scanning laser active imaging technology,range gated imagingowns some special advantages, such as miniaturization, high frame frequency, high field of view, and so on. 首先,根据研究课题的应用背景与需求,分析比较了不同体制的激光成像技...
We have investigated the effect of size parameter of the scatterer on the image quality obtained with polarization-based range-gated imaging in birefringent turbid medium.Both linearly and circularly polarized light were utilized for imaging. The simulated results indicate that the improvement of ...

Modern thermal imaging solutions simply aren't up to the job. That's why companies are now turning to Obzerv Technologies Inc. - the team behind the cutting-edge range-gating technology that is set to transform the industry. The company's innovative long-gated cameras are ideal for a wide ...
In this paper, we proposed an adjacent frame difference (AFD) method to reconstruct 3-dimension (3D) images for range-gated flash imaging Lidars. In this novel method, the range information of the target is obtained by thresholding the intensity difference between two adjacent frames from the in...
