Abstract
An improved DNA sequencing system comprising a DNA sample holder residing on a stacked BSI global shutter image sensor illuminated by a pulsed laser for fluorescent illumination detection. The pulsed laser has on and off periods wherein during the laser on period a Fluorophore tag attached to a DNA sample is excited to produce fluorescence emission while the imaging system captures no illumination and during the off period the global shutter imaging system captures persistent fluorescent emission from the DNA sample and reads out an imaging signal.
