Arrangement for optically reading out the information from substrates having a multiplicity of individual samples
First Claim
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.

Abstract
An arrangement is disclosed for optically reading out the information from substrates having a multiplicity of individual samples, in particular for analyzing chemical and biological sample carriers. The arrangement presents a new possibility for optically reading out the information from matrix-type substrates having a multiplicity of individual samples which allows a fast read-out of a radiation which is influenced by the individual samples with a high degree of sensitivity. This possibility is achieved by the fact that, in the case of optically reading a matrix-type substrate having a multiplicity of metrically ordered pixels, the receiver that is provided is an individual receiver which has high sensitivity and a uniform receiver area, an electrooptical matrix and also an imaging optical system are present, each substrate pixel being assigned to a matrix pixel region by the imaging optical system, and the matrix can be driven in such a way that matrix regions which allow exclusively the feeding of radiation from a 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 suitably chosen time interval. The result is that it is possible to evaluate a series of measured radiation quantities from selected sequences of substrate pixels at the output of the receiver.
