Electrowetting prism device and multi-view 3d image display apparatus including the same

Номер: US20140126038A1
Принадлежит: SAMSUNG ELECTRONICS CO LTD

Provided are an electrowetting prism device which has increased an aperture ratio by simplifying an electrode and wiring structure, and a 3D image display apparatus capable of providing a super multi-view 3D image using the electrowetting prism device. The electrowetting prism device includes lower and upper transparent substrates disposed against each other, a vertical wall mounted on the lower transparent substrate so as to form a diamond-shaped space, a first electrode arranged along two adjacent sidewalls of the vertical wall, a second electrode arranged along the other remaining two adjacent sidewalls of the vertical wall to be disposed against the first electrode, and a non-polarized liquid and a polarized liquid arranged within a space surrounded by the vertical wall.

A method of calibrating a fluorescence in-situ hybridization (FISH) system includes contacting a calibration slide with a plurality of probes, obtaining one or more images of the calibration slide; and calibrating the FISH system based on the one or more images. The calibration slide has a surface with a first plurality of beads. Each bead of the first plurality of beads has one or more binding domains. Each probe has a tag and a targeting domain, and the targeting domain binds a binding domain from the at least one binding domain.

Image Capture with Digital Light Path Length Modulation

Номер: US20180048814A1
Принадлежит: Avegant Corp

An image capture system comprising an optical path length extender (OPLE) to direct the light having a first polarization through a first light path through the OPLE, and to direct the light having a second polarization through a second light path through the OPLE, the first and second light paths having different light path lengths. The image capture system further comprising an image sensor to capture a plurality of image portions at a plurality of focal distances.
