    CMOS RD2600X4MS

    RD2600X4MS is a state-of-the-art Backside Illuminated (BSI) all CMOS VIS-NIR multi-array bidirectional line scanning detector. The detector is made of a single Silicon die with 4 independent lines, each with 2600 pixels. Pixel design is based on state of the art high gain, low noise, 4T CMOS technology providing very high sensitivity. The signal to noise ratio is improved by Time-Delay-Integration (TDI) per pixel with controllable depth of up to 64 levels. A built-in 2-phase scanning mechanism improves the dynamic MTF by reducing the scanning motion blur. An Electronic Shutter accurately controls the exposure time per each line, enabling optimized exposure as well as additional dynamic MTF improvement. The Silicon die is housed in a sealed ceramic package providing very accurate mechanical interfaces and excellent heat transfer. The ceramic package is sealed with a glass window positioned in adjacent to the photo-sensitive focal plane array. The glass window can support custom optical filters where each line is exposed to different spectral band (total of 4 bands). The electrical signal collected from the pixels is converted into 12-bit digital signal using on-chip analog-to-digital converters. The digital image output simplifies the system design and enables image transmission with no additional noise. On board voltage regulators simplifies the power supplies requirements. The electrical interface to the system is through high reliability, easy to use, connectors. All of these together with additional built-in features simplify the electrical interface. The detector power consumption is very low, its weight and size are minimized, and thus enables a very compact system solution. The CMOS die is RADHard by design. Along with other aspects it makes this detector compatible for space applications.
