This is the new smallest image sensor in the world. A technological feat that we owe to the company OmniVision, which goes directly into the record books. This technological gem is the size of the tip of a needle.
Its nice name OV6948, its main use will concern medical examinations. Thanks to its extreme dimensions, it would be particularly practical to explore and evaluate the inside of a patient's body, at the request of a surgeon.
Record characteristics
With a slice-shaped design, and dimensions of only 0.65 mm x 0.65 mm² (for a thickness of 1,158 mm), this photosensor is a little larger than a grain of sand. It can be used with catheters or endoscopes, for the better comfort of the patient. An interesting solution against the procedures sometimes considered invasive and inconvenient.Technically, this photosensor allows rendering in a resolution of 200 × 200 pixels (similar to some webcams of the 2000s), with 30 frames per second. All for a 120 ° field of view, and a focusing range of 30 to 30 mm. The transmission of images is based on an analog function with a range of up to 4 meters.
Another interesting fact: its resistance to extreme temperatures. Unlike more traditional probes, this photosensor is functional between temperatures ranging from -20 ° C to 70 ° C.
A sensor that opens up new possibilities
Designed for the exploration of a human body, this sensor must respond to several constraints. For example, it is able to add light (1,000 mV / lux-sec) in an environment where there is none or display colors that are close to reality while reducing noise. the image.Consuming almost no electrical energy (only 25 mW of power), this technological jewel emerges, therefore, almost no heat. This allows longer periods of manipulation inside patients.
Mainly intended for pre-surgical uses, the use of this sensor could very quickly expand: ENT, urological, veterinary, dental examination ... Many professions could benefit from it.
