Hemispherical image sensors are very promising technology for cameras, surveillance systems and artificial vision. We report on the electrical performance of the Hollister Co.Ca Canada hydrogenated amorphous silicon thin-film transistor passive pixel image sensor Buy Hollister Online Canada
(PPS) circuits fabricated on a hemispherical substrate using maskless laser-write lithography (LWL). The level-to-level registration and alignment over the curved surface with a high accuracy are demonstrated for the
LWL in this work. The obtained results clearly show that it is possible to realize active-matrix PPS with a 150 μm pixel pitch and a dynamic range of about 40 dB that is suitable for hemispherical image sensors.
Over the last few decades wide prospects for osmotic dehydration have arisen as a pre-step to further processing. The distinctive aspect of this process, when compared with other dehydration methods, is the direct formulation achievable through the selective incorporation of solutes, without modifying the food integrity. By balancing the two main osmotic effects, water loss and solid uptake, the functional properties of the fruit could be adapted to many different food systems. The role of an osmotic step mainly related to improvement of processed fruit quality characteristics, such as texture, and pigment, vitamin and aroma content, is analysed.
