Within this work we present a first experimental setup of a high-resolution real-timecapable 3D sonar camera system for deep sea operation. Since we are currently in the development process, the focus of this work is on the transmission aspects of the camera. Following publications will include the receiving aspects as well as the first phantom reconstructions. The system consists of a 1024 element matrix array antenna, together with a 128 channel beamforming system including a 1:8 multiplexing device for each channel. The camera is supposed to deliver volumetric images within a range of up to 15 m in a deep sea environment up to 6000 m depth. The antenna provides the advantage of an adjustable defocused transmitting sound field. This allows dynamic control of the field of view, and an increase of the image contrast for a specific region.

Uncooled infrared focal plane arrays are being developed for a wide range of thermal imaging applications. Fire-fighting, predictive maintenance, process control and thermography are a few of the industrial applications which could take benefit from uncooled infrared detector. Therefore, to answer these markets, a 35-µm pixel-pitch uncooled IR detector technology has been developed enabling high performance 160x120 and 384x288 arrays production. Besides a wide-band version from uncooled 320x240/45 µm array has been also developed in order to address process control and more precisely industrial furnaces control. The ULIS amorphous silicon technology is well adapted to manufacture low cost detector in mass production. After some brief microbolometer technological background, we present the characterization of 35 µm pixel-pitch detector as well as the wide-band 320x240 infrared focal plane arrays with a pixel pitch of 45 µm.
