The submitted photograph must be made with a lensless photographic device: pinhole, multiple pinholes, zone plate
, slit, etc, in either a homemade or commercial camera.
The optic is a variant of something called a Fresnel zone plate
A Fresnel zone plate
(FZP) is an important optical element with light collecting properties and it has many applications in the visible light, millimeter waves, extreme-UV, and x-ray domain regions [1-6].
The preliminary location of the earthquake indicates this is an intraplate event, 50 or more kilometers to the east of the subduction zone plate
boundary between the Philippine Sea and Sunda plates.
An internal library of static standard test patterns is included, as well as dynamic patterns including a real time zone plate
generator EBU AV Sync audio synchronization pattern and a LCD panel persistence test.
Interestingly, the volcanics are located within a few hundred kilometres of, but are laterally offset from, the Calabrian subduction zone plate
boundary, where the African plate sinks below the Eurasian plate," said Schellart.
Each zone plate
is a set of radially symmetric rings, just 5 mm dia.
From a beginner's introduction to pinhole cameras to expanded information and zone plate
practices for more advanced users, this is packed with color photos of the latest, most original pinhole results.
Both the Phabrix-Sx handheld and Phabrix-Rx 2U rack mounted systems incorporate a wide range of advanced functions, including: SDI test signal generation and TX; zone plate
generation, video RX analysis and capture; video scaling for all 3G/HD/SD SDI video formats on a 4.
There is new material in this book on RFCMOS, Freznel zone plate
antennas, and RFICs.
003 keV) was focused to a spot ~1 [micro]m in diameter using a gold zone plate
of 150 p.
Hudec uses a lensless camera called a zone plate
pinhole, which allows her to render life the way she sees it--fleeting, sensual and fragile.
