Sony's first 'curved sensor' photo may herald better images, cheaper lenses

We have seen loads of curved screens, however Sony has simply revealed the primary image taken with a curved picture sensor which will in the future deliver cheaper, smaller lenses and better photograph high quality. Common, flat digital camera sensors have a relatively giant drawback referred to as “Petzval subject curvature.” That happens when mild rays passing by way of the sting of a lens fall in entrance of the sensor’s focal aircraft, slightly than on it. In consequence, optical designers should add pricey parts to lenses, which additionally makes them heavier and extra complicated. The shot above flaunted by Sony is only a check and there are not any excessive-decision samples obtainable but; actually Sony has indicated that prime-megapixel sensors could also be a methods off. Nevertheless, it does mark the primary picture proven from Sony’s curved CMOS sensor and a potential new path for its digital digital camera division.

A sensor with the sides bent towards the lens takes care of many optical sins. Sony constructed its prototype curved sensor flat, bent it right into a form generally known as a “Petzval floor” and strengthened it with a ceramic backplate. That geometry permits shorter, lighter lenses with bigger apertures that permit extra mild in. As well as, such a design additionally reduces mild falloff on the edges of a typical flat CMOS sensor, and the method of bending a sensor introduces pressure within the photodiodes that really advantages them by decreasing noise. Lastly, Sony added that its sensors work the identical method because the human eye to repair optical points, and also have a comparable degree of curvature.

As such, Sony has constructed a 2/three-inch prototype sensor sometimes seen in compact cameras, together with a full-body model. Because it occurs, the latter sensor would work very properly in an RX1-sort digital camera. When such sensors arrive commercially, they’re probably for use in fastened lens and never mirrorless or DSLR fashions to start out with, since they would not work with any present lenses available on the market. In truth, there is a rumor that a attainable RX2 might be introduced in September at Photokina 2014 — we’re not holding our breath for a curved sensor on it, however you by no means know.
