1. An arrangement for optical reading out the information from a matrix-type substrate having a multiplicity of individual samples, which represent metrically ordered pixels on the substrate and emit a radiation which is characteristically influenced by an individual sample substance, comprising:

  • a receiver;

    a transfer optical arrangement for separately transferring the radiation emitted by individual substrate pixels to said receiver;

    said receiver being a single receiver which has a high sensitivity and a uniform receiver area and being able to take up the radiation from each substrate pixel;

    said transfer optical arrangement having an electro-optical matrix, which has the function of a variable light valve for separately transferring radiation from each substrate pixel to the receiver and being arranged in such a way that each substrate pixel being imaged in an optical one-to-one-assigned manner to a matrix region comprising at least one matrix pixel; and

    said matrix being able to be driven in such a way that matrix regions of such a size which allow the feeding of radiation from only one substrate pixel to the receiver can be switched separately, radiation quantities from in each case at least one substrate pixel successively impinging on the receiver over a suitable chosen time interval, so that it is possible to evaluate a series of measured radiation quantities from selected sequences of substrate pixels at the output of the receiver.
