Description

Technical Field

[0001] The utility model relates to the technical field of fluorescence imaging, in particular to a non-contact laser fluorescence imaging acquisition device. Background Art

[0002] Fluorescence is a common luminescence phenomenon in nature. Fluorescence is produced by the interaction between photons and molecules. This interaction process can be described by the Jablonski molecular energy level diagram: most molecules are in the lowest vibrational energy level So of the ground state under normal conditions. When excited by energy (light energy, electrical energy, chemical energy, etc.), the electrons around the nucleus transition from the ground state energy level So to the higher energy excited state (first or second excited state). The excited electrons are in a high energy state and unstable. They will release energy back to the ground state through two pathways. One is the radiative transition that releases energy in the form of photons (including fluorescence and phosphorescence processes), and the other is the non-radiative transition that releases energy in the form of heat energy. Usually, after the electrons outside the nucleus are excited and transition from the ground state So to the excited state Si, they will quickly land at the lowest vibrational energy level through non-radiative transitions, and then return to the ground state from the lowest vibrational energy level, releasing energy in the form of photon radiation. The emitted light with this property is called fluorescence. Fluorescence imaging can be used in medicine to help doctors confirm the patient's condition, which has extremely high practical value.
