Disclosed is an optoacoustic-fluorescence dual-mode endoscope (10) comprising a control system (11), a laser light source (12), a optical system (13), an endoscope tube (14), a scanning system (15), a data acquisition system (16), an image reconstruction system (17) and a display system (18). The control system (11) controls the laser light source (12), the scanning system (15), the data acquisition system (16), the image reconstruction system (17) and the display system (18). The laser system (12), the optical system (13), the scanning system (15) and the endoscope tube (14) are sequentially connected, and the data acquisition system (16), the optical system (13) and the endoscope tube (14) are connected. The data acquisition system (16), the image reconstruction system (17) and the display system (18) are sequentially connected. This dual-mode endoscope (10) realizes integration of two imaging modes by simultaneously leading the excited optoacoustic and the fluorescent light into the endoscope tube (14), and irradiating into a biological tissue, after a focused photoscope has focused, while exciting the optoacoustic signal and the fluorescence excitation signal, and the imaging resolution is greatly improved.Linvention concerne un endoscope (10) double mode à fluorescence optoacoustique comprenant un système de commande (11), une source de lumière laser (12), un système optique (13), un tube dendoscope (14), un système de balayage (15), un système dacquisition de données (16), un système de reconstruction dimage (17) et un système daffichage (18).
