Innovative focal plane segmentation for high-resolution planetary observation
Author(s): Grégoire Hein; Marc Ferrari; Nicolas Tetaz

Paper Abstract

As of today, Earth and planetary high-resolution observations rely on linear focal plane arrays used in TDI mode to acquire images delivered by the telescope. To both reach high angular resolution and keep a large field-of-view, homothetic imaging systems as used in Pleiades satellites or Mars Reconnaissance Orbiter [1] would lead to prohibitive linear focal plane dimensions. Reducing this parameter would therefore allow for a significant decrease in the size of space optical systems. The solution described in this paper intends to optically reduce this dimension by segmenting the linear FOV into smaller sub-fields that are stacked on a CMOS TDI sensor. It is therefore possible to drastically reduce the linear size of the array, at the expense however of a small increase in terms of complexity of the optical system.
