Abstract
Apparatus and methods for optical detection with improved read speed and/or signal-to-noise ratio. These apparatus and methods may involve among others moving an sample substrate (,) while simulataneously detecting light transmitted from one or more sample sites (,) on the substrate (,) by sequentially tracking the sample sites (,) as they move. A stage (,), movable in a first direction, supports the substrate (,). A detector (,) detects light emanating from an examination region (,) delimited by a detection initiation position (,) and a detection termination position (,). An optical relay structure (,) transmit light from the examination region (,) to the detector (,). A scanning mechanism (,) simultaneously moves the optical relay structure (,) and the substrate in the first direction. The optical relay structure (,) tracks the substrate (,) between the detection initiation position (,) and the detection termination position (,).
