SPR curves measured in each of 16 image regions. Gold sensing surface was exposed to water and images were collected as the incident angle was scanned from <62 degrees to >65.5 degrees. Reflected intensity was normalized to the same measurement performed on a bare glass surface. During operation, incident angle is typically adjusted to a position on the curve close to the dotted line. Increases in refractive index cause the curve to move to the right, increasing the observed brightness.
