    摘要: The invention relates to a method and device for identifying luminescent molecules according to the fluorescence correlation spectroscopy method. The inventive method comprising the following steps: a) preparing a sample (12) containing luminescent molecules; b) illuminating the sample (12) using an optical excitation device (2,4,6,8) comprising at least one light source, at least one, in particular, diffractive optical element (7) for splitting light passing therethrough into multiple beams, and a focusing optics (8) for focusing multiple light beams passing therethrough into multiple confocal volume elements: c) capturing emission radiation from the multiple confocal volume elements by means of a locally resolving sensor matrix arrangement (20), whereby the sensor matrix arrangement is a sensor matrix, which is comprised of avalanche photodiodes AD is produced using IC technology, particularly CMOS technology, and is integrated in a sensor chip (20) with Greiger-mode wiring, and; d) processing the signals, which are provided by the avalanche photodiode matrix, by means of a signal processing and evaluation device preferably integrated in the sensor chip.

    摘要: A high-speed laser perfusion imaging instrument including a laser source, a detector, a signal-processing unit, data memory, and a screen to display results. A section of a sample surface is illuminated with laser light; reemitted light from the irradiated surface is collected by focusing optics on a 2D array of integrating photodetectors having elements that can be accessed individually or in a pre-defined selection of pixels at high speed. This 2D array measures intensity variations at each individual pixel. Average amplitude and mean frequency of the measured signal contain information about concentration and speed of moving blood cells. For real-time imaging, exposure time is used as a parameter to measure relative perfusion changes. These data are stored and processed with the signal-processing unit to deliver 2D flow maps of the illuminated sample section, and allow a simple overlay between a conventional image and processed flow maps.
