This means that, from the threshold triangle width w (in m) and the distance between test pattern and the camera D (in m) the smallest discernable detail ωc (in arcmin) is calculated as follows:
Il s &apos; ensuit qu &apos; à partir de la largeur seuil du triangle w (m) et de la distance entre le motif d &apos; essai et la caméra D (m), le plus petit détail discernable ωc (arc-min) est calculé comme suit:
