Abstract

The laser sheet light source system of the present invention comprises: a first reflector, a second reflector, a Fresnel lens, a grid fine-tuning device, an argon ion laser, a heat exchanger and a cooling tower. One end of the heat exchanger forms an outer circulation loop with the cooling tower, and the other end of the heat exchanger forms an inner circulation loop with the resonant cavity cooling chamber of the argon ion laser, and the cooling water circulates in the outer circulation loop and the inner circulation loop respectively. The laser beam emitted by the argon ion laser passes through the grid fine-tuning device, the Fresnel lens, the second reflector and the first reflector in sequence. The grid fine-tuning device, the argon ion laser, the Fresnel lens, the second reflector and the first reflector are respectively installed on the sheet light turning device. The heat exchange system of the present invention ensures the safe operation of the laser; the grid fine-tuning device can flexibly adjust the transmission orientation of the high-power laser beam, and at the same time, the sheet light steering device can flexibly adjust the transmission height and orientation of the sheet light, which greatly facilitates users Change the measurement section.

Description

technical field

[0001] The invention relates to a laser beam sheet light source system for plane laser beam induced fluorescence imaging. Background technique

[0002] "Planar laser-induced fluorescence imaging" technology (abbreviated as PLIF----"planar laser-induced fluorescence imaging"). All the application of sheet light source to irradiate the measured object, so that the fluorescent substance contained in it excites (induces) the fluorescent signal, and the fluorescent image is recorded by the camera equipment, and the light intensity field (gray level) contains the concentration field information of the fluorescent substance. The experimental technique for this detection is called PLIF.

[0003] The generation system of the sheet light source generally uses a cylindrical lens to expand the laser beam into a fan-shaped sheet light after the laser beam is produced. The lateral light intensity distribution of the sheet light still maintains the Gaussian distribution in...
