CSS Engineers have teamed with Sarnoff/SRI in the design of a CMOS image sensor that is slated to be aboard the Naval Research Laboratory”s Solar Orbiter Heliospheric Imager (SoloHI).  This work is a continuation of a long teaming relationship with Sarnoff, having completed 16 earlier “tape-outs” of new designs.

The SoloHI”s detector is a 4K x 4K Advanced Pixel Sensor using CMOS technology, as shown below.


The 4K x 4K Advanced Pixel CMOS Sensor

This will be the first time such a large format APS detector has flown. The instrument will make high-resolution images of the corona and solar wind, including coronal mass ejections (CMEs), to determine how they propagate and interact with the background solar wind. With its large field of view, SoloHI will be able to connect the remote sensing observations of the corona to the plasma being measured in-situ at the spacecraft.
