Abstract
In this work, we report a new SPR sensor configuration which enables a single-point detection strategy for 2D angular interrogated SPR sensor array. The single-point detection strategy for 2D SPR measurements is enabled by the cooperation of two digital micro-mirror devices (DMDs). Specifically, one DMD is used to conduct spatial scanning along the vertical direction of the sensor chip; and the other DMD is used to conduct spatial scanning along the horizontal direction. Thanks to the programmability of DMDs, arbitrary and instant access of interrogation angle and sensing site are achieved with no limitation in integration time. Besides, no mechanical scanning is required in the entire system. This configuration suffices a single-point detector for 2D angular interrogated SPR measurements that can be readily optimized for nearly ideal performance, increased sensing capacity without sacrificing the sensitivity.
