ANALYTICAL SYSTEM, AND METHOD FOR ANALYZING NONLINEAR OPTICAL SIGNALS

摘要

The invention relates to a method for the ultrasensitive simultaneous measurement of nonlinear optical emission signals in one or two local dimensions. Said method comprises the following steps: the excitation light is irradiated in a power-modulated or pulse-modulated form from at least one light source into an interactive volume or onto an interactive area or layer (hereafter called interactive spaces ) in which one or several emissions tha t are nonlinearly correlated with the excitement light can be excited; the lig ht emanating from said interactive spaces is measured by means of a one- dimensional or two-dimensional detector array; the measured data is transmitted from said detector array to a computer; and said data is formatt ed in a one-dimensional or two-dimensional data matrix. The inventive method is characterized in that non-correlated portions of the light emanating from th e interactive spaces or the portions thereof that are linearly proportionate t o the intensity of the excitement light available in said interactive spaces a re separated from portions of the light emanating from the interactive spaces, which are not linearly proportionate to the intensity of the available excitement light. The invention further relates to an analytical system that is suitable for carrying out the inventive method.
