Systems and methods are described for enabling a lensless camera having an image sensor and a mask to be positioned behind a display screen of a device, which allows for the device to have an increased screen-to-body ratio. The image sensor captures an image based on the light that travels through the display screen and the mask. The display screen may include portions between pixel elements that allow light to pass through. The mask may include a pattern, such as an opaque material with portions that allow light to pass through from the portions of the display layer to the image sensor. The image captured by the image sensor may be indiscernible to humans. The system may utilize a trained machine learning model to reconstruct the image, using data about the pattern of the mask, so humans may visually recognize features in the image.

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.
