    摘要： A method for the quantitative representation of the blood flow in a tissue or vascular region is based on the signal of a contrast agent injected into the blood. In the method, several individual images of the signal emitted by the tissue or vascular region are recorded at successive points in time and are stored. Based on the respective signal, a quantity characteristic for the blood flow and a quantity characteristic for the position of the blood vessels are determined for image areas of individual images. These quantities are represented superimposed for the respective image areas such that both the blood flow quantity and the position of the fine blood vessels become clearly visible in the representation and can be differentiated from the tissue.

    摘要： A coherence microscope has a divider (3) that divides light emitted by a light source (1) into measurement light, which is supplied to and reflected by a specimen (13), and reference light. A superimposition device (25, 31) superimposes the measurement light reflected by the specimen (13) with the reference light. A short sensor array (41) detects the light resulting from the superimposition and permits a read-out rate of at least about 60 kHz. The superimposition device has an emission device (25, 31) for emitting the measurement light and the reference light arranged to effect extensive irradiation of the sensor array (41) with superimposed light. The ratio of distances covered by the measurement light and the reference light from the emission device (25, 31) to impingement points on the sensor array (41) varies in the portion of the sensor array (41) that is irradiated with superimposed light.

    摘要： An image sensor and a circuitry associated with the image sensor is used for recording a series of fluorescence images. The image sensor comprises a plurality of pixels for accumulating charges generated by incident radiation, and the circuitry converts the charges accumulated in the pixels into binary numbers. A gain of the circuitry is adjustable. The gain is set to a suitable maximum value at the beginning of a recording procedure. The gain is reduced if it is determined during the recording procedure that one or more brightness values of the recorded image exceed a suitably chosen maximum brightness value.
