The speckle effects caused by the coherence of the laser light sources have restricted the performances of angular surface plasmon resonance (SPR) imaging sensors, which are widely used due to their wide linear rage, high refractive index (RI) resolution, and simple structure. In this work, we experimentally studied the influence of two common despeckle methods (laser with a rotating diffuser and an incoherent light-emitting diodes (LED) light source) on the RI resolution of an angular SPR imaging sensor. We found that the LED light source with a band-pass filter could not only eliminate the speckle effect completely but also provide better RI resolution than the other despeckle method. This low-cost speckle-free method has the potential to promote the development and the industrialization of angular SPR imaging sensors.
