Abstract:
An imaging flow cytometry apparatus and method which allows registering multiple locations across a cell, and/or across multiple flow channels, in parallel using radio-frequency-tagged emission (FIRE) coupled with a parallel optical detection scheme toward increasing analysis throughput. An optical source is modulated by multiple RF frequencies to produce an optical interrogation beam having a spatially distributed beat frequency. This beam is directed to one or more focused streams of cells whose responsive fluorescence, in different frequencies, is registered in parallel by an optical detector.

Abstract:
Systems and methods for digital pathology in accordance with embodiments of the invention obtain a whole slide image of a microscope slide that includes a registration mark, wherein the registration mark is associated with a coordinate system. The method inputs the whole slide image into a region identification (RI) model to extract features of the whole slide image and generate feature vectors for the extracted features, detects a presence of a region of interest (ROI) based on the feature vectors, determines a set of coordinates of the ROI in the coordinate system, and translates a microscope stage of a microscope holding the microscope slide to a position corresponding to the coordinates of the ROI. The method captures a field of view (FOV) image with the microscope and inputs the FOV image into a grading model to determine a pathology score that indicates a likelihood of a presence of a disease.

Abstract:
Apparatus and/or method for performing single-shot network analysis of electrical, electronic and electro-optical elements (e.g., components, circuits, modules, sub-systems and/or systems) on a device, or devices, under test (DUT). A pulsed optical source is directed through a first dispersion element to an modulator, while a delayed version of the pulsed optical source is directed to the DUT (pulsed optical source converted to electrical signal if DUT has electrical input), whose electrical output is fed to the modulator whose modulated optical pulse output is stretched through a second optical dispersion element, then converted to an electrical signal and processed to provide analysis and/or display of DUT response.

Abstract:
A feature-selective compression method and system are described which uses a transformation causing feature-selective stretching of the image being compressed. As a result, additional samples are allocated to sharp features where they are needed, and less to coarse features where they are redundant. The method can be applied to still and video images, whether they are monochrome or color images or 3D images, and operates in open-loop fashion and does not require prior knowledge of the image. The method can be applied by itself or combined with other types of compression (i.e., JPEG, WebP) to further compress the image.
Abstract:
An apparatus and method for ultrafast real-time optical imaging that can be used for imaging dynamic events such as microfluidics or laser surgery is provided. The apparatus and methods encode spatial information from a sample into a back reflection of a two-dimensional spectral brush that is generated with a two-dimensional disperser and a light source that is mapped in to the time domain with a temporal disperser. The temporal waveform is preferably captured by an optical detector, converted to an electrical signal that is digitized and processed to provide two dimensional and three dimensional images. The produced signals can be optically or electronically amplified. Detection may be improved with correlation matching against a database in the time domain or the spatial domain. Embodiments for endoscopy, microscopy and simultaneous imaging and laser ablation with a single fiber are illustrated.
