摘要:
According to the invention, two simultaneous images with different wavelengths (λ1, λ2) are formed in synchronism with each illuminance laser pulse, one of the Images corresponding to the wavelength (λ1) of the laser pulses, and the difference between the two images is generated.
摘要:
The invention comprises illuminating a scene where said magnifying optical system (OP) may occur with at least a first and a second pulses respectively generated by first and second laser transmitters (E1, E2). The first laser transmitter (E1) and a detector of the scene thus illuminated (D) are adjacent, while the second laser transmitter (E2) is remote from said detector (D) transversally to the direction (d) of said scene.

Gaseous flux laser generator of the nitrogen and carbon dioxyde type. The dimensions of the enclosure and the conditions of injection of the nitrogen and those of the electrical supply are chosen to set up a luminescent discharge in a swirling flow.
摘要:
The invention comprises illuminating a scene where said magnifying optical system (OP) may occur with at least one pulse generated by first laser transmitter (E). The laser transmitter (E) and a first detector of the scene thus illuminated (D1) are adjacent, while a second detector (D2) is remote from said transmitter (E) transversally to the direction (d) of said scene.
