Sensor resolution is the number of pixels in the camera sensor divided by the physical size of an object in the Field-of-View (FOV) of the scene. Imaging Gauge™ divides the number of pixels between corners of the SFR feature by the physical size of the SFR feature to calculate the Sensor Resolution.
For example, if an image is captured with N = 500 pixels between corners of the slanted-edge feature, the following Sensor Resolution measurements would be reported, depending on the physical target size.
The image on the left was captured at 50 dpi while the unacceptable image on the right was captured at 20 dpi.
The Sensor Resolution upper and lower specification limits can be set in the Sensor Resolution tab. An upper limit on Sensor Resolution is intended to limit file size, if necessary.
