Ακούγονται κινέζικα; Λοιπόν η Sony ετοιμάζεται να εξελίξει μια νέα τεχνολογία για αισθητήρες. Με μια πρόταση, η τεχνολογία επιτρέπει να περνά περισσότερο φως. Διαβάστε παρακάτω τι είναι ένας αισθητήρας Quantum Film.
QuantumFilm Technology involves the creation of a film to coat the image sensors used in a cellphone camera, allowing it to capture more light, improving the quality of the images taken.[9][10] A typical camera phone pixel sensor is made up of several layers, with a layer of colored plastic or glass acting as a color filter sitting on top of several layers of metal connecting silicon electronic transistors together, which is itself on top of a base layer of silicon used by the sensor’s electronic transistors and photodetectors. The light coming to the sensor has to pass through the layers of metal before reaching the silicon, a weak light absorber, so the sensor detects only about 25 percent of the light that makes up the image.[11] QuantumFilm Technology places a layer of semiconducting crystals – called quantum dots – on top of the chip, which allows the chip to absorb more light, place more pixels in a smaller space, and create sharper images.[12]
Using quantum dots is more efficient at capturing light than traditional silicon-based image sensor chips (capturing 90-95% of the light that hits it), giving the sensors higher sensitivity in low light as well as higher resolution.[3][13] And while traditional image sensors read an image from top to bottom (which can create a blurred image when the subject is moving), quantum dots detect the entire image at the same moment, reducing the chance for distortion.[14]
