Espros Photonic sent me its June 2015 Newsletter which, I guess, will eventually appear on its web site. The company CEO, Beat De Coi, tells about their ToF sensor product, and promises to tell more in the next Newsletter edition:
"The ESPROS TOF technology is gaining huge momentum. The delivery start of the 3D-TOF QVGA imager was excellent. Customers immediately recognized the performance of our OHC15L technology. A QE of more than 80% at 850nm wavelength and pixels with 100% fill factor provide unmatched sensitivity with very low illumination power. A reference design of a camera engine with a horizontal FOV of 94° achieves a 10m range in the full field. Ok, this is on a white target. But the exposure time is a few milliseconds only."
Espros also opens a Youtube channel with a video demo of its epc660 ToF imager:
PORE PRESSURE and its typesPore pressure is defined as the pressure acting on the fluids in the pore spaces of the rock. This is the scientific meaning of what is generally referred to as formation (pore) pressure. Depending on the magnitude of pore pr…Read More
CAUSES OF ABNORMAL PORE PRESSUREAbnormal pore pressure is developed as a result of a combination of geological, geochemical, geophysical and mechanical process as will be discussed in the following paragraphs. These causes may be summarized under:• Depositi…Read More
OVERBURDEN PRESSUREThe overburden pressure is defined as the pressure exerted by the total weight of overlying formations above the point of interest. The total weight is the combined weight of both the formation solids (rock matrix) and format…Read More
EFFECTS OF WATER DEPTH ON OVERBURDEN GRADIENTIn offshore operations, the depth of the sea (length of the water column) determines howmuch the overburden gradient is reduced. The reduction in overburden gradient is due towater being less dense than rock and for a given h…Read More
