FIELD: hydrooptics, underwater acoustics. SUBSTANCE: invention may be used to detect and examine underwater objects by underwater optical and acoustic means. Traditional underwater photographic camera is fitted with fiber-optical underwater listening device. Characteristic of directivity of underwater listening device is directed along optical axis of photographic camera. Potential for taking pictures of underwater object at moment when lens of photographic camera is directed to source of noise in underwater object. EFFECT: higher efficiency. 7 cl, 2 dwg
