Considerations for Using Line Scan Cameras
When using line scan cameras, there are a few things to consider:
Movement speed synchronicity:The moving speed of the object or camera needs to match the shooting speed to ensure that the image is not distorted.
Light source settings:A stable and uniform light source needs to be provided to avoid uneven image brightness.
Data processing speed:Since high-resolution images are generated, sufficient processing power is required to handle large amounts of data.
Resolution and scanning speed:It needs to be selected according to the balance between the size of the object to be inspected and the speed of the production line.
Interface type:GigE Vision has cost advantages, and CoaXPress is suitable for high transmission requirements.
Spectral requirements:If you need to identify subtle color differences or infrared features, consider RGB or multispectral cameras.
Institutional installation:The line scanning system needs to move or rotate the platform synchronously to ensure the continuity of the scanning line.
Light source and lens selection suggestions
light source:Use linear LED light sources and choose diffuse, coaxial or oblique light sources based on surface reflection characteristics.
Lens:It is recommended to use a Telecentric lens to reduce geometric distortion; if the scan width is large, a dedicated Line Scan lens can be used.
Filter:Polarizing or narrowband filters can be installed for specific wavelength bands or reflective objects.
Comprehensive suggestions
If the application is a high-speed production line (such as steel strip, glass, semiconductor), it is recommended to choose Teledyne DALSA or Vieworks series; if the main purpose is general inspection, choose Basler or JAI brand.
