A device for analysis of a test object using photo-acoustic effect and a method for controlling inducing of a photo-acoustic effect

Abstract

A device for analysis of a test object using photo-acoustic effect comprises: an optical arrangement configured to output spatially separated light comprising a plurality of wavelengths, wherein light of different wavelengths of the plurality of wavelengths is separated into different spatial directions; and a spatial light modulator configured to receive the spatially separated light, wherein the spatial light modulator comprises a plurality of individually controllable regions, wherein each individually controllable region is configured to receive a portion of the spatially separated light for associating each individually controllable region with a specific wavelength of the plurality of wavelengths, wherein each individually controllable region is configured to modulate the portion of the spatially separated light with a modulation frequency for generating modulated light for inducing a photo-acoustic effect in the test object.
