Gemba Walks are often done in a layered manner. At the lowest layer, the Department Manager does a daily walk, and an hourly associate presents the data. At these daily walks, it is common for the local maintenance mechanics, engineers, and QC technicians to participate.
LIDAR is similar to the radar commonly used to track everything from airplanes in flight to thunderstorms. But instead of bouncing radio waves off its target, LIDAR uses short pulses of laser light. Some of that light reflects off of tiny particles in the atmosphere and back to a telescope aligned with the laser.
LIDAR sensors are capable of receiving multiple returns, some up to five returns per pulse. This means that a 30-KHz sensor (30,000 pulses per second) must be capable of recording up to 150,000 returns per second. The first return recorded by a LIDAR sensor is the first thing hit by a laser pulse.This could be a treetop, roof, ground point, or a bird in flight. When a laser pulse hits a soft target (e.g., a forest canopy), the first return represents the top of that feature.he first return recorded by a LIDAR sensor is the first thing hit by a laser pulse.
