| Definition | An acoustic camera. It provides almost video-quality images in turbid or dark water where optical systems are ineffective. DIDSON uses acoustic lenses to focus beams and form an acoustic image on the transducer array. DIDSON forms images differently than an optical camera. DIDSON sends out short acoustic pulses in 48 or 96 acoustic beams. These beams are very narrow in the horizontal dimension (0.3deg to 0.8deg) and wide in the vertical dimension (14deg). The beams are adjacent to each other and together form a field-of-view 29deg horizontal and 14deg vertical. The Didson 3000 is rated to a depth of 3000m. Has both Detection and Identification modes. Max frame rate (window length dependent) 4-21 frames/s. | ||
