How to interpret the Dynamic Range and Signal to Noise Ratio (SNR) in image sensor and industrial camera specifications

With machine vision applications, some of the most important specifications beyond resolution and frame speed to determine whether the camera meet the measurement requirements, are full well capacity, Signal to Noise Ratio (SNR), and dynamic range (DR) specifications.  Interpreting these values from specification sheets can be challenging though.  The full well capacity and SNR definitions…
