Title
(EN) AN APPARATUS, A HANDHELD ELECTRONIC DEVICE, AND A METHOD FOR CARRYING OUT RAMAN SPECTROSCOPY
(FR) APPAREIL, DISPOSITIF ÉLECTRONIQUE PORTATIF ET PROCÉDÉ DE RÉALISATION D'UNE SPECTROSCOPIE RAMAN
Abstract
(EN)
An apparatus (101), a handheld electronic device (201) and a method for carrying out Raman Spectroscopy are disclosed. In an embodiment an apparatus includes at least one optoelectronic laser (203) configured to provide excitation radiation (207) to a sample (205), the excitation radiation (207) being generated by an electric current flowing through the at least one optoelectronic laser (203) during operation of the apparatus and a transistor (211) configured to modulate the electric current flowing through the at least one optoelectronic laser (203), to thereby switch on and off generation of the excitation radiation (207).
(FR)
Un appareil (101), un dispositif électronique portatif (201) et un procédé de réalisation d'une spectroscopie Raman sont divulgués. Dans un mode de réalisation, un appareil comprend au moins un laser optoélectronique (203) configuré pour fournir un rayonnement d'excitation (207) à un échantillon (205), le rayonnement d'excitation (207) étant généré par un courant électrique circulant à travers l'au moins un laser optoélectronique (203) pendant le fonctionnement de l'appareil et un transistor (211) configuré pour moduler le courant électrique circulant à travers l'au moins un laser optoélectronique (203), ce qui permet d'allumer et d'éteindre la génération du rayonnement d'excitation (207).
