interferometers (VSI) measure the surface height of smooth to moderately rough surfaces, providing nanometre vertical resolution, regardless of the numerical aperture, to make use of all available magnifications to profile shape features.
One of the reasons why their system uses fewer lasers per unit--it could be one, it could be four--is because the laser is directed in a raster pattern so that there is horizontal and vertical scanning
. (The InnovizOne has a field of view of 125 x 25 degrees.)
According to Panasonic, existing LiDAR products used in advanced driver assist systems (ADAS) or autonomous vehicles suffer from the problem of having a vertical scanning
angle that is fixed and too narrow.
First, the focused laser beam scans the target structure vertically upward and the laser beam steps horizontally leftward after vertical scanning
. Then the laser beam scans vertically downward as shown in Figure 1.
looks up and helps to analyze storm tops, gradients and cell buildup activity at higher altitudes.
Humminbird also offers a vertical scanning
system called Down Imaging.
Other useful features include an automated scanning mount that enables full 260 degree horizontal and 120 degree vertical scanning
, so the systems response does not depend on path length.
Using a new focus-variation vertical scanning
microscope, the researchers could see extensive surface detail like never before.
With cameras and monitors, several versions of HD are in use and are described by horizontal lines of resolution and the type of vertical scanning
This result is in agreement with the prediction from the optical geometry and thus supports the possibility of a phototaxis mechanism based on a simultaneous comparison of two receptor signals during sideways scanning but not vertical scanning
. However, the optical geometry and behavior also agree with a mechanism involving a pooled-receptor signal during both sideways and vertical scanning
To maximise the efficiency of the scan and reduce the optical pathway, OBM is using a complex optical system combining a Bravais lens system (US Patent 5966252, 1999) which has a negative power, two holographic optical elements, a telephoto Fourier transform, a demagnifying transform lens and a vertical scanning
