Quality inspection applications for electronic manufacturers.
An imaging technique that is not so common in machine vision is Line Scan Imaging. Instead of using an area or a matrix sensor, a line sensor has a linear sensor array capturing a single row of pixels.
Using a Laser Profile Scanner, we can inspect solder pins on a PCB in 3 Dimensions. You can easily detect defects such as open solders, shorts and over / under solder on a pin.
