摘要： The invention describes a laser sensor module (100) for particle size detection. The laser sensor module (100) comprises at least one first laser (110), at least one first detector (120), at least one electrical driver (130) and at least one evaluator (140). The first laser (110) is adapted to emit first laser light in reaction to signals provided by the at least one driver (130). The at least one first detector (120) is adapted to determine a first self -mixing interference signal (30) of an optical wave within a first laser cavity of the first laser (110). The first self-mixing interference signal (30) is caused by first reflected laser light reentering the first laser cavity, the first reflected laser light being reflected by a particle receiving at least a part of the first laser light. The evaluator (140) is adapted to determine a size of the particle by determining a first relative distance between the particle and the first laser (110) by means of the first self-mixing interference signal (30) and by determining a first amplitude information by means of the first self-mixing interference signal (30). The invention is further related to a corresponding method of determining a particle size.

摘要： Apparatus and methods for detecting, characterizing, and compensating motion-related error of moving micro-entities are described. Motion-related error may occur in streams of moving micro-entities, and may represent a deviation in and expected arrival time or an uncertainty in position of a micro-entity within the stream. Motion-related error of micro-entities is observed in a flow cytometer, e.g., as pulse jitter, and is found to have a functional dependence on a parameter of the system. The pulse jitter can be compensated, according to one embodiment, by adjusting data acquisition observation windows. For the flow cytometer, a reduction of pulse jitter can improve measurement accuracy, resolution of doublets, system throughput, and enable an increase in an interrogation region for probing the micro-entities.

摘要： Particular embodiments of the inventive technology relate to 'off-axis detector' technology that employs a third detector 23 exhibiting a flow orthogonal axis 43 as defined by its EMR collection angle, where such axis is from 30 degrees to 60 degrees from an intended, flow orthogonal, cell cross section long axis alignment line 13, in addition to employing a fourth detector 24 exhibiting a flow orthogonal axis 44 as defined by its collection angle, where such axis is orthogonal to the flow orthogonal, third detector axis 43. Particular embodiments of the inventive technology relate to 'axially spaced illumination' technology featuring more than one cell illumination site, where, other than the most upflow illumination site (e.g., 121), all illumination site(s) are downflow of at least one other illumination site. Particular embodiments of the inventive technology may feature aspects of both technologies.

摘要： Methods, storage mediums, and systems for correlating pulses generated from multiple interrogation regions in a flow cytometer to particular particles flowing through the flow cytometer are provided. Embodiments of the methods, storage mediums, and systems include configurations for calibrating a flow cytometer using a calibration particle having a unique signature to determine a time-of-flight for particles flowing through the flow cytometer. Based on the calculated time-of-flight and relative positions of interrogation regions corresponding to collectors of the flow cytometer, the methods, storage mediums, and systems may further include configurations for associating other signal pulses to particles of one or more different particle sets.

摘要： The present invention relates to a method and apparatus which can provide rapid scanning of large specimens (14) to detect and determine positions of objects having specific characteristics. The apparatus may, further, be adapted to store information associated with the positions of the detected objects and to retrieve this position information so that an oparator may locate a particular type of target object or objects in the specimen for detailed inspection and analysis subsequent to the scanning. The position information may be stored in a volatile or non-volatile memory device provided therefore in a preferred embodiment of the invention. The specimen may be provided on a solid support, such as a circular disc (13) which may be rotatably mounted about an axis (17) of a frame of the apparatus. The objects can be cells or microorganisms of a particular rare type, i.e. they may be present in a very low density in the specimen.
