Abstract
The present disclosure relates to an optical apparatus for imaging and/or manipulating micro-objects in a microfluidic device, such as a light-actuated microfluidic (LAMF) device, and related systems and methods. The optical apparatus can comprise a structured light modulator, a first and a second tube lens, an objective lens, a dichroic beam splitter, and an image sensor. The structured light modulator can be configured to receive unstructured light beams and transmit structured light beams for illuminating micro-objects located within an enclosure of the microfluidic device and/or selectively activating one or more of a plurality of dielectrophoresis (DEP) electrodes of the microfluidic device. The image light beams received by the image sensor can be used to form an image of at least a portion of the microfluidic device.
