WebApr 12, 2024 · Using one-photon excitation (405 nm), the probability of a molecule absorbing a photon is higher than that using two-photon excitation (800 nm), so tissues have a higher intensity fluorescence at 405 nm (Figure 2d) than at 800 nm (Figure 2c). However, two-photon excitation is able to efficiently excite some molecule types (here, lipopigments ... WebJul 14, 2024 · In this model, the camera/sensor is a single pixel that takes an input (a number of photons) and transforms this number to an output (a digital value in analog-to-digital units, or ADU). In performing this transformation, various sources of noise are added to the signal so that, given a camera's output in ADU, we can only make probabilisitic ...
