    Abstract: Light from an object moving through an imaging system is collected, dispersed, and imaged onto a time delay integration (TDI) detector that is inclined relative to an axis of motion of the object, producing a pixilated output signal. In one embodiment, the movement of the image object over the TDI detector is asynchronous with the movement of the output signal producing an output signal that is a composite of the image of the object at varying focal point along the focal plane. In another embodiment, light from the object is periodically incident on the inclined TDI detector, producing a plurality of spaced apart images and corresponding output signals that propagate across the TDI detector. The inclined plane enables images of FISH probes or other components within an object to be produced at different focal points, so that the 3D spatial relationship between the FISH probes or components can be resolved.

    Abstract: Frequency domain velocity measurements and time domain velocity measurements are made using light from cells or other objects. An optical grating is used to modulate the light from an object so that it has a frequency proportional to the velocity of the object. Depending upon the embodiment, the pitch of the optical grating is uniform or varying. The modulated light is detected, producing an analog signal that is then digitally sampled. Time domain signal processing techniques are used to determine the velocity of the object from the digital samples. Preferably, the velocity measured is applied in determining a timing signal employed for synchronization of an image of the object and an detector signal in an optical analysis system that uses a time delay integration (TDI) detector to determine characteristics of the object in response to light from the object.

    Abstract: Multimodal/multispectral images of a population of cells are simultaneously collected (402). Photometric and/or morphometric features identifiable in the images (404) are used to separate the population of cells into a plurality of subpopulations. Where the population of cells includes diseased cells and healthy cells, the images can be separated into a healthy subpopulation, and a diseased subpopulation (408). Where the population of cells does not include diseased cells, one or more ratios of different cell types in patients not having a disease condition can be compared to the corresponding ratios in patients having the disease condition, enabling the disease condition to be detected. For example, blood cells can be separated into different types based on their images, and an increase in the number of lymphocytes, a phenomenon associated with chronic lymphocytic leukemia, can readily be detected.

    Abstract: A pair of optical gratings (126, 134) are used to modulate light from an object (102), and the modulated light from either optical is used to determine the velocity of the object. Each optical grating is offset from a reference focal point by the same distance, one grating being offset in a positive direction, the other in a negative direction. Signals produced in response to the modulated light can be processed to determine a direction in which a primary collection lens (110) should be moved in order to improve a focus of the imaging system on the object. The lens is moved incrementally in the direction so determined, and the process is repeated until an optimal focus is achieved. In a preferred embodiment, the signals are weighted, so that the optical grating disposed closest to the optimal focus position contributes the most to velocity detection.

    Abstract: Light from an object (152) moving through an imaging system (154) is collected, dispersed, and imaged onto a time delay integration (TDI) detector (148) that is inclined relative to an axis of motion of the object, producing a pixilated output signal. In one embodiment, the movement of the image object over the TDI detector (148) is asynchronous with the movement of the output signal producing an output signal that is a composite of the image of the object at varying focal point along the focal plane. In another embodiment, light from the object is periodically incident on the inclined TDI, producing a plurality of spaced apart images and corresponding output signals that propagate across the TDI detector (148).

    Abstract: A labeling method that labels an object or specific features of an object with labeled probes that provide a multiplexed signal that can be analyzed by spectral decomposition. This binary and higher encoding scheme can be employed to label components of biological cells. In each encoding scheme, labeled probes that selectively bind to a specific feature are required. The labeled probes include a binding element that binds to the feature, and at least one signaling component that generates a detectable signal, preferably a spectral signature. In one embodiment, adding multiple fluorescent dye molecules to each binding element provides the multiplexed signal. In another embodiment, adding only one signal compound to each binding element provides the multiplexed signal, such that some of the binding elements have a different signal compound added. The different signal compounds provide the multiplexed signal.
