Device and method for performing lens-free imaging

摘要

The invention relates to an imaging device (1) comprising a photonic integrated circuit (2). This photonic integrated circuit comprises an integrated waveguide (4) for guiding a light signal (5), a light coupler (8) optically coupled to the integrated waveguide (4) and adapted for directing the light signal (5) out of the plane of the waveguide (4) as a light beam (9), and a microfluidic channel (98) for containing an object (12) immersed in a fluid medium. The microfluidic channel is configured to enable, in operation of the device, illumination of the object by the light beam. The integrated circuit further comprises at least one imaging detector (11) positioned for imaging the object (12) illuminated by the light beam (9). The invention also relates to a corresponding method for imaging.
