摘要： A method and system are provided for illuminating and imaging a biological sample using a brightfield microscope for the purpose of counting biological cells. The method comprises the steps of, by a processing device: a. positioning a sample to be viewed by way of an objective lens of the microscope, and on an x-y plane at an x-y position of a plurality of x-y positions, the sample comprising a plurality of biological cells; b. capturing and storing, using an image capturing apparatus, one or more focal image stacks, each said focal image stack comprising a plurality of focal images of the sample positioned at the x-y position, each of the focal images in the focal image stack being captured at a different focal position of a plurality of discrete focal positions within a focal range, the focal range being located on a z plane perpendicular to the x-y plane; c. processing the one or more focal image stacks using a cell localisation neural network, the cell localisation neural network outputting a list of one or more cell locations, each said cell location corresponding to a cell characteristic determined by the cell localisation neural network; d. determining, using the list of cell locations, one or more cell focal image stacks, each cell focal image stack being obtained from the one or more focal image stacks; and e. processing the one or more cell focal image stacks using an encoder neural network, the encoder neural network outputting a list of cell fingerprints, each said cell fingerprint corresponding to a cell of the plurality of biological cells; f. determining, using the list of cell locations and the list of cell fingerprints, a number of cells within the sample. The present disclosure aims to provide a quick, non-invasive and reliable mode of counting biological cells.

摘要： An example device may include a light source, an optical element, and, optionally, an encapsulant layer. A light beam generated by the light source may be received by the optical element and redirected towards an illumination target, such as an eye of a user. The optical element may include a material, for example, with a refractive index of at least approximately 2 at a wavelength of the light beam. The light source may be a semiconductor light source, such as a light-emitting diode or a laser. The optical element may be supported by an emissive surface of the light source. Refraction at an exit surface of the optical element, and/or within a metamaterial layer, may advantageously modify the beam properties, for example, in relation to illuminating a target. In some examples, the light source and optical element may be integrated into a monolithic light source module.
