Abstract
The disclosure provides a structured illumination imaging system that utilizes an image sensor (e.g., an active pixel sensor) in an active plane of a patterned sample to increase image resolution. The imaged sample may be patterned and/or aligned over an image sensor such that each light sensor (e.g., pixel) of the image sensor has a respective plurality of features formed and/or mounted above it. In response to illumination, each of the features may emit fluorescent light that is collected by a pixel of the image sensor. During imaging, each pixel of the image sensor may be spatially multiplexed using structured illumination such that only a subset (e.g., one or two) of the features aligned over the pixel are illuminated with structured light during an image read.
