Patent ID: 7545494

Claim:
A method for highly sensitive simultaneous measurement of nonlinear optical emission signals, spatially resolved in one or two spatial dimensions, comprising: radiating excitation light from at least one light source in a power-modulated and/or pulse-duration-modulated form into interaction spaces, in each of which one or a plurality of emissions that are correlated nonlinearly with the excitation light can be excited, measuring light emerging from said interaction spaces by means of a one- or two-dimensional detector array, transmitting measurement data from said detector array to a computer and formatting the data in a one- or multidimensional data matrix, characterized in that data representative of those portions of the light emerging from the interaction spaces which are linearly proportional to the intensity of the excitation light available in the interaction spaces are separated from data representative of the portions of the light emerging from the interaction spaces which are nonlinearly proportional to the available excitation light intensity.
