摘要

1. An optical research device (10) configured to at least partially be placed in a cloudy environment, said optical research device comprising a barrel portion (21) configured to be placed in a cloudy environment, said barrel portion (21) comprises a tip portion (22) configured to be a front portion during placement in a cloudy environment in which at least one light source device configured to emit a broadband beam (11) Oh light is provided in the region of the section of the barrel (21), made with the possibility of placement in a muddy environment, and the beam (11) of broadband light contains various bands (2a, 2b ..., 2n) of wavelengths that are modulated in different ways; and at least one photodetector (27a, 27b, 27c) for detecting broadband light is provided in an area configured to place a portion (21) of the barrel in the muddy environment. An optical research device according to claim 1, characterized in that at least one photodetector (27a, 27b, 27c) is electrically connected to a section of an optical research device configured to remain outside a cloudy medium. An optical research device according to one of the preceding claims, characterized in that at least one photodetector (27a, 27b, 27c) is a photodiode. An optical research device according to one of claims 1 and 2, characterized in that the barrel section (21) is provided with a plurality of photodetectors (27a, 27b, 27c) located in different places relative to the barrel section (21). 5.
