Optomechanical design of multiscale gigapixel digital camera

Applied Optics, 2013
Recent developments in multiscale imaging systems have opened up the possibility for commercially viable wide-field gigapixel cameras. While multiscale design principles allow tremendous simplification of the optical design, they place increased emphasis on optomechanics and system level integration of the camera as a whole.

A Multiscale, Wide Field, Gigapixel Camera

Imaging and Applied Optics, 2011
Recent investigations into high pixel count imaging using multiscale optics have led to a novel optical design for a wide field, gigapixel camera. We review the mechanical design and optical performance of this imager.

A Digital Gigapixel Large-Format Tile-Scan Camera

IEEE Computer Graphics and Applications, 2011
Although the resolution of single-lens reflex (SLR) and medium-format digital cameras has increased in recent years, applications for cultural-heritage preservation and computational photography require even higher resolutions. Addressing this issue, a large-format cameras' large image planes can achieve very high resolution without compromising pixel ...

Towards Real-Time Gigapixel Video

2017
In the previous chapter, we explained the design flow and the full hardware implementation of Panoptic, a real-time omnidirectional multi-camera system. Panoptic is a miniaturized system consisting of fifteen cell phone cameras providing 256 × 1024 resolution output.

Reconstruction of Gigapixel Stereometric Maps of Ceramic Surfaces

2018
For the purposes of the paper, a three-dimensional geometric structure of a biomaterial surface was reconstructed well above an individual field of view using a laser confocal microscope and systematic scanning. The entire analysed area was divided using a square grid with regular component fields in both columns and rows.
