Abstract
An imaging method includes assigning pixels within the extent of a focal plane array active area to a first readout range and a second readout range. Image data is read out from the pixels assigned to the first readout range and the second readout range. Pixels located within the extend of the focal plane array active area and not assigned to the first readout range or the second readout range are left unread. Imaging systems and hyperspectral imaging arrangements are also described.
Claims17
An imaging method, comprising:
- assigning pixels within a focal plane (FPA) active area extent to a first readout range and a second readout range;
- reading out image data from pixels assigned to the first readout range;
- reading out image data from pixels assigned to the second readout range;
- and
- leaving unread pixels located within the FPA active area extent and not assigned to the first readout range or the second readout range, further comprising applying a first gain to a first set of pixels within the first readout range, and applying a second gain to a second set of pixels within the first readout range.

An imaging system, comprising:
- a focal plane array (FPA) having an active area with a pixel array;
- a readout integrated circuit (ROIC) in electrical communication with the pixel array;
- and
- a controller operably connected to the ROIC and disposed in communication with a non-transitory machine readable memory having instructions recorded on it that, when read by the controller, cause the controller to:
- assign pixels within a focal plane (FPA) active area extent to a first readout range and a second readout range;
- read out image data from pixels assigned to the first readout range and the second readout range;
- and
- leave unread pixels located within the FPA active area extent and not assigned to the first readout range and the second readout range, wherein the instructions further cause the controller to apply a first gain to image data acquired from a first set of pixels within the first readout range, and apply a second gain to image data acquired from a second set of pixels within first readout range.

A hyperspectral imaging arrangement, comprising:
- an imaging system, comprising:
- a focal plane array (FPA) having an active area with a pixel array;
- a readout integrated circuit (ROIC) in electrical communication with the pixel array;
- and
- a controller operably connected to the ROIC and disposed in communication with a non-transitory machine readable memory having instructions recorded on it that, when read by the controller, cause the controller to:
- assign pixels within a focal plane (FPA) active area extent to a first readout range and a second readout range;
- read out image data from pixels assigned to the first readout range and the second readout range;
- and
- leave unread pixels located within the FPA active area extent and not assigned to the first readout range and the second readout range;
- and
- a multi-slit spectrometer optically coupled to the FPA, the multi-slit spectrometer optically coupled to the FPA and configured to apply a slit of illumination to the pixels assigned to the first readout range and the instructions further cause the controller to:
- apply a first gain to image data acquired from a first set of pixels within the first readout range;
- and
- apply a second gain to image data acquired from a second set of pixels within the first readout range.
