Abstract:
A device is described allowing simultaneous control of angles at which an optical beam is impinging a sample and at which radiation emitted by the sample is collected. The device comprises a first electrically addressed spatial light modulator configured to block input light and produce an excitation radiation for irradiating a sample at the predetermined incidence angle; a second electrically addressed spatial light modulator configured to produce the detection radiation corresponding to the predetermined collection angle; and at least one controller configured to control at least one of: the predetermined incidence angle by controlling the first electrically addressed spatial light modulator and the predetermined collection angle by controlling the second electrically addressed spatial light modulator. The device can be applied in the field of Raman spectroscopy for investigation, which can be used to identify tensor components of stress in silicon wafers.

Claim (Index 17):
A method for irradiating a sample at a predetermined incidence angle and collecting detection radiation at a predetermined collection angle, the method comprising;\n generating an input light; partially blocking the input light by placing a first electrically addressed spatial light modulator along an optical path of the input light to produce an excitation radiation having predetermined spatial characteristics for irradiating the sample; focusing the excitation radiation by at least one focusing element at the predetermined incidence angle onto a surface of the sample, the predetermined incidence angle being based on the predetermined spatial characteristics; collecting radiation emitted from the surface of the sample by the at least one focusing element to produce a collimated radiation; partially blocking the collimated radiation by placing a second electrically addressed spatial light modulator along an optical path of the collimated radiation to produce a detection radiation having predetermined spatial characteristics corresponding to the predetermined collection angle, the predetermined collection angle being controlled by the second electrically addressed spatial light modulator; and controlling at least one of the first electrically addressed spatial light modulator and the second electrically addressed spatial light modulator by at least one controller to control the predetermined incidence angle and the predetermined collection angle.
