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.

Multiplexing of an active sensor detector using structured illumination

Light detection devices and related methods are provided. The devices may comprise a reaction structure for containing a reaction solution with a relatively high or low pH and a plurality of reaction sites that generate light emissions. The devices may comprise a device base comprising a plurality of light sensors, device circuitry coupled to the light sensors, and a plurality of light guides that block excitation light but permit the light emissions to pass to a light sensor. The device base may also include a shield layer extending about each light guide between each light guide and the device circuitry, and a protection layer that is chemically inert with respect to the reaction solution extending about each light guide between each light guide and the shield layer. The protection layer prevents reaction solution that passes through the reaction structure and the light guide from interacting with the device circuitry.
