Camera Interfaces and Bandwidth
The interface decides whether the data can be moved in time. Insufficient bandwidth does not appear as a slugg…

Wavelength, Polarisation and Filters
Lighting is often treated as an illumination problem — brighter is surely clearer. It is the opposite. The job…

Choosing a Telecentric Lens
A standard lens forms a perspective image: bring the part closer and it gets bigger on the sensor. That is com…

Accuracy Conversion
The usual mistake is to start from the camera: "twenty megapixels ought to be enough." The chain runs the othe…

Alarm Fatigue: Why the Floor Turns the System Off
Many visual SOP systems are not beaten by technical problems — they are muted by the floor. Once alarm fatigue…

Traceability Granularity
Piece-level traceability is treated as the ambition and batch-level as the compromise, which is backwards. In …
