How to use the output of the optical flow module
An Optical Flow setup requires a downward facing camera and a downward facing distance sensor (preferably a LiDAR). These can be combined in a single product, such as the Ark Flow and Holybro H-Flo.

Installation loss of jumper wires tested with optical power meter
The one-jumper reference method is your go-to technique for accurately testing fiber optic links that terminate in connectors at both ends. It's recognized by industry standards like TIA-568 as the most precise way to measure the loss of the installed cable plant. You'll be testing the entire cable plant, including the loss from. In order to test the fibers in a fiber optic cable with a power meter and source or with an OTDR, one needs to establish test conditions. The test conditions should be similar to how the actual cable plant will be used when communications equipment is connected (see drawing below. more This video explains how to use a one test jumper method using the Tempo Communications Optical Power. This Applications Engineering Note (AEN 135) explains and recommends standard measurement methods for characterizing optical fiber system performance.

The Role of the Optical Flow Positioning and Obstacle Avoidance Module
The optical flow vectors can help us to separate the motion caused by camera motion from the motion caused by incoming objects without relying on training data. This paper describes the development of an optical flow-based airborne obstacle detection algorithm to avoid mid-air collisions. The image obtained from a monocular camera is first split into two horizontal and vertical half planes.

Fixed Optical Flow Module
Optical Flow uses a downward facing camera and a downward facing distance sensor for velocity estimation. It can be used to determine speed when navigating without GNSS — in buildings, undergr.
