Unlocking the Invisible with Sony SWIR Picture Sensors

Sony’s Brief-Wave Infrared (SWIR) picture sensors are reworking industries by permitting the detection of supplies and substances invisible to the human eye. That is a part of a bigger push on sensors, a site Sony may be very profitable in.

By harnessing particular wavelengths of sunshine, SWIR sensors seize photographs not solely within the seen spectrum but in addition within the short-wavelength infrared area, enabling superior functions throughout varied sectors, reminiscent of meals inspection, materials sorting, contaminant detection, and semiconductor manufacturing. We’ve seen a live demo at CEATEC 2024 in Japan.

One key attribute of SWIR expertise is its skill to distinguish between supplies based mostly on their absorption and reflection of sunshine at particular wavelengths. For example, water, which often seems clear in seen gentle, absorbs SWIR gentle, inflicting it to seem black.

This property makes it extremely efficient for figuring out moisture ranges in objects, reminiscent of in meals inspection, the place figuring out the presence of moisture could be vital for guaranteeing high quality and security. SWIR sensors, due to this fact, permit for the detection of overseas objects and contaminants that will be tough or inconceivable to establish with the bare eye.

Moreover, SWIR sensors also can seize high-resolution photographs in environments the place seen gentle is obstructed. Their skill to see by way of mist or smoke enhances their utility in varied functions the place environmental circumstances can restrict visibility.

This makes them invaluable in precision inspections, the place figuring out minute contaminants or defects could be essential for operational effectivity and high quality management.

Sony’s innovation on this area facilities on its SenSWIR expertise, a wide-band and high-sensitivity SWIR picture sensor. This expertise merges compound semiconductor InGaAs (Indium Gallium Arsenide) photodiodes with silicon readout circuits by way of Cu-Cu bonding, enhancing the sensor’s sensitivity and efficiency.

SenSWIR sensors provide improved imaging precision, enabling industries to see past the floor and detect the undetectable, enhancing productiveness and inspection accuracy.Sony’s SWIR picture sensors, significantly the SenSWIR technology, are setting new requirements in imaging by capturing invisible wavelengths of sunshine.

Their utility in industries like meals security, materials sorting, and semiconductor inspection is revolutionizing how these sectors establish and handle beforehand undetectable points.
