WebNegative aspects to mention are: 1) Process speed slowly 2) Part handling – the component needs to be placed into a rotary axis 3) Rotation of the part is not always pos- sible These disadvantages have been the main reasons why laser plastic welding projects were difficult to be realized in the past. Webresponse is a function of the input irradiance level. We can only perform LSI analysis for a restricted range of input irradiances. Another linearity consideration is that coherent optical systems (optical processors) are linear in electric field (V/cm), while incoherent systems (imaging systems) are linear in irradiance (W/cm2). We will deal ...
