MULTIPLEX ILLUMINATOR AND DEVICE READER FOR MICROCANTILEVER ARRAY

摘要

A device reader having a multiplex illuminator, the illuminator, and methods for reading deflection of a large number of microcantilevers are provided. The illuminator includes a micro-optical subassembly (illuminator) (101) for illuminating array (103) of cantilevers (103a) that includes a plurality of VCSELs (101a) for generating an array of electromagnetic beams (101b), and focuses the beams on the cantilevers (103a). Deflection of the cantilevers (103a) causes a change in angle of the beams reflected from the cantilevers (103a), which is recorded by an array (106) which includes a plurality of position sensitive devices (106a).
