In one aspect, embodiments disclosed herein relate to a lens-free imaging system. The lens-free imaging system includes: an image sampler, a radiation source, a mask disposed between the image sampler and a scene, and an image sampler processor. The image sampler processor obtains signals from the image sampler that is exposed, through the mask, to radiation scattered by the scene which is illuminated by the radiation source. The image sampler processor then estimates an image of the scene based on the signals from the image sampler, processed using a transfer function that relates the signals and the scene.

摘要:
High-definition particle detection during centrifugation of a pharmaceutical liquid is provided. Centrifugation of fluid containers drives particles to the interior surface of the container if the particles are denser than the fluid and to the middle of the container if the particles are less dense than the fluid. The imager can then be focused directly on the particle itself for rapid identification without the need for computing complex particle trajectories. If the centrifugation of the container is carried out at an angle to the axis of symmetry of the container, particles can be driven to a single line on the interior surface of the container by the centrifugal force, making the identification of the particles even more straightforward than in two dimensions. The particle imager can also be attached to the rotating container to prevent blurring of the particle image due to the relative motion of the container and imager.

Provided is a medical imaging device comprising: a color separation prism that has a dichroic film configured to split light into first light belonging to a visible light wavelength band and second light belonging to a fluorescence wavelength band; a fluorescence image sensor that is provided at an output side of the color separation prism and that is configured to image at least part of the second light belonging to the fluorescence wavelength band separated by the dichroic film; a visible light image sensor that is provided at the output side of the color separation prism and that is configured to image at least part of the first light belonging to the visible light wavelength band separated by the dichroic film; and a bandpass filter that is disposed between the color separation prism and the fluorescence image sensor, wherein the fluorescence image sensor and the visible light image sensor are arranged such that an optical path difference between an optical path length of a fluorescence optical path for the second light imaged on the fluorescence image sensor via the color separation prism and an optical path length of a visible light optical path for the first light imaged on the visible light image sensor via the color separation prism corresponds to an amount of a shift between a fluorescence imaging position and a visible light imaging position, the shift being generated by an imaging lens positioned at an input side of the color separation prism, and wherein the fluorescence imaging position is an imaging position of filtered second light, which results from passing the second light through the bandpass filter, such that the amount of shift is based on the filtered second light.

A system for operating an electrokinetic device includes a support configured to hold and operatively couple with the electrokinetic device, an integrated electrical signal generation subsystem configured to apply a biasing voltage across a pair of electrodes in the electrokinetic device, and a light modulating subsystem configured to emit structured light onto the electrokinetic device. The system can further include a thermally controlled flow controller, and/or be configured to measure impedance across the electrokinetic device. The system can be a light microscope, including an optical train. The system can further include a light pipe, which can be part of the light modulating system, and which can be configured to supply light of substantially uniform intensity to the light modulating system or directly to the optical train.

The invention relates to an imaging optical system (40) which is used to analyze a lithography mask within a metrology system. Said lithography mask can be arranged in an object field (3) of the imaging optical system. Said object field (3) is defined by two object field coordinates (x, y) which are mutually perpendicular. The imaging optical system (40) comprises an aperture diaphragm (42), the aspect ratio thereof in the direction of both object field coordinates is different by 1. As a result, an imaging optical system which can be used to analyze lithography masks which are designed for projection lithography by means of an anamorphotic projection optical system is obtained.
