| titleOfInvention | A kind of solution detection method and device based on golden film photo-thermal effect |
| abstract | A kind of method of highly sensitive real-time detection solution concentration and type, based on pump probe technology and photo-thermal sink effect, golden film is irradiated using pump light, golden film generates heat after absorbing light, and be transmitted in detected solution around, since temperature change causes detected solution refraction index changing around during heat propagation.It will be detected in the way of light is focused through prism total internal reflection and be irradiated in golden film by convex lens, reflected light is separated the light of s polarization and p-polarization using polarization spectro, the electric signal difference of s polarization and p-polarization is measured by balanced detector, and then obtains the variations in refractive index due to caused by photo-thermal effect.Pump light is modulated in the measurements, and modulation intelligence feedback is input to lock-in amplifier into lock-in amplifier, while by differential detector electric signal, realizes the measurement to Photothermal Signals using locking phase enlarging function.The present invention is suitable for highly sensitive real-time detection solution concentration and type. |
