    摘要: Aspects of the present invention encompass the collection of multispectral images from a population of objects, and the analysis of the collected images to measure at least one characteristic of the population, using photometric and/or morphometric features identifiable in the collection of images. In an exemplary application, the objects are biological cells. In a particularly preferred, but not limiting implementation, the plurality of images for each individual object are collected simultaneously. In an empirical study, the characteristic being measured involves the synapse between conjugated cells. The conjugated cells may represent a subpopulation of the overall population of objects that were imaged. In a particularly preferred, yet not limiting embodiment, the present invention enables the quantization of the redistribution of cellular molecules due to the conjugation of different biological cells. Significantly, such quantization is not feasible with standard microscopy and flow cytometry.

    摘要: An illumination system for increasing a light signal from an object passing through a reflection cavity. The reflection cavity is disposed between spaced-apart, opposed first and second surfaces disposed on opposite sides of a moving stream of objects. A light collection system is disposed substantially orthogonal to a plane passing through the surfaces and the stream so as to collect light that is scattered from or emitted by the objects as they pass through a field of view disposed between the first and second surfaces. A beam of light from a laser source is directed through the stream of moving objects in a direction nearly orthogonal to the stream (but slightly inclined) and lying in the plane that extends through the surfaces and the stream. Due to the reflection angle and the distance between the stream and the first surface, the point at which the light reflected from the first surface intersects the stream on a second pass is displaced from where it passed though the stream on its initial pass. The light is reflected back and forth between the surfaces a plurality of times, illuminating a different portion of the field of view with each pass until, having ranged over the field of view, the light exits the reflection cavity. The “recycling” of the light beam in this manner substantially improves the SNR of the detection system by increasing an average illumination intensity experienced by the objects in the stream.

    摘要: Light from an object such as a cell moving through an imaging system is collected and dispersed so that it can be imaged onto a detector. The light can be emitted from a luminous object or can be light from a light source that has been scattered or not absorbed by the object or can include a light emission by one or more probes within or on the object. Multiple objects passing through the imaging system can be imaged, producing both scatter images and dispersed images at different locations on one or more detectors. In one embodiment, the detector is divided into a plurality of zones so that each of a plurality of different images are spectrally dispersed onto a different zone of the detector.
