An imaging apparatus may include a light source emitting linear light, a light reflector configured to reflect the linear light incident from the light source unit, a first filter configured to filter the linear light reflected from the light reflector, a light transmission reflector configured to reflect the linear light passing through the first filter toward an object and transmit light incident from the object, a second filter configured to filter the light that has passed through the light transmission reflector after being incident from the object, and a camera configured to capture the light passing through the second filter.

Apparatus and method for rendering an image of a fibrous material. The method includes providing parametric fibrous material optical properties derived from actual material fiber samples via the apparatus; providing a parametric virtual light environment; providing a virtual fibrous material array; and rendering an image of the virtual fibrous material array according to the interaction of the parametric fibrous material properties and the parametric virtual light environment.

Implementations disclosed herein include a method of imaging an albedo of an astronomical object in space. The method includes arranging an imaging system in space with an orientation facing the object. The imaging system includes a lensless image sensor with the orientation that captures images of the object. The method also includes maintaining the imaging system with the orientation facing the object during an imaging data capture session, and it includes capturing near-continuous images with the imaging system during the imaging data capture session. The orientation is maintained for subsequent image data capture sessions. For some implementations, the imaging system includes a lensed image sensor, and capturing the near-continuous images includes simultaneously capturing time-correlated images of the object with the lensed image sensor and the lensless image sensor.
