Two-photon microscopy is a fluorescence imaging technique in which two beams of coherent laser light are focused … WebJul 17, 2015 · Fluorescence microscopy imaging speed is fundamentally limited by the measurement signal-to-noise ratio (SNR). To improve image SNR for a given image acquisition rate, computational denoising ...
WebThe advantages of fluorescence detection over absorbance detection are sensitivity, as well as application range, given the wide selection of fluorescent labels available today. For example, a technique known as calcium imaging measures the fluorescence intensity of calcium-sensitive dyes to assess intracellular calcium levels. [citation needed]
