Elliptical photo-acoustic sensor |
摘要 |
An elliptical photo-acoustic spectrometer chamber design will result in a larger intensity signal at the pick-up microphone and allow high frequency light modulation. This makes the spectrometer have a lower limit of detection threshold, and will increase the signal to noise ratio in general for the instrument, resulting in a more sensitive instrument allowing more precise measurements. |
