Abstract
To provide a sheet-like structure capable of highly accurately estimating a sheet-like shape. A sheet-like structure includes a sheet-like member and a plurality of detection sensors. The sheet-like member extends along an in-plane direction orthogonal to a thickness direction and receives light incident on the sheet-like member. The plurality of detection sensors are dispersedly arranged on the sheet-like member along the in-plane direction and are for detecting an incident angle of the light with respect to the sheet-like member at each arrangement position of the plurality of detection sensors.
Claims7
A sheet-like structure, comprising:
- a sheet-like member that extends along an in-plane direction orthogonal to a thickness direction and receives light incident on the sheet-like member, wherein the sheet-like member is composed of bendable material;
- and
- a plurality of detection sensors that are dispersedly arranged on the sheet-like member along the in-plane direction and are for detecting an incident angle of the light with respect to a normal direction of the sheet-like member at each arrangement position of the plurality of detection sensors,
- wherein each detection sensor of the plurality of detection sensors comprises a detection region that receives the light and is arranged along the in-plane direction, and
- wherein light shielding is omitted from the detection region of each detection sensor, such that an entirety of the detection region of each detection sensor receives the light.
A spacecraft, comprising:
- a sheet-like structure;
- and
- a main body connected to the sheet-like structure, the sheet-like structure including
- a sheet-like member that extends along an in-plane direction orthogonal to a thickness direction and receives light incident on the sheet-like member, wherein the sheet-like member is composed of bendable material;
- and
- a plurality of detection sensors that are dispersedly arranged on the sheet-like member along the in-plane direction and are for detecting an incident angle of the light with respect to a normal direction of the sheet-like member at each arrangement position of the plurality of detection sensors,
- wherein each detection sensor of the plurality of detection sensors comprises a detection region that receives the light and is arranged along the in-plane direction, and
- wherein light shielding is omitted from the detection region of each detection sensor, such that an entirety of the detection region of each detection sensor receives the light.
