What is SWIR CMOS Sensor
SWIR, Short-Wave Infrared generally refers to the wavelength band of light between 900nm and 2500nm. Traditional silicon sensors have an upper limit of approximately 1100nm. SWIR imaging usually requires sensors and camera components capable of operation in the SWIR range using Indium Gallium Arsenide (InGaAs) sensors (typically in the 900nm to 1700nm range)– which are inherently expensive and face challenges in scaling to smaller pixel pitches and higher resolution arrays. A CMOS SWIR sensor is capable of SWIR wavelength detection without to use of compound semiconductor materials, based purely on CMOS (silicon) manufacturing process. It’s cost effective technology that enable seamless integration.
What can a QPD™ SWIR camera do?
Medium Material Detection
SWIR wavelengths are absorbed and reflected according to the material, therefore you can detect things hidden in visible light.
Package Component Detection
Certain plastics or objects become transparent using SWIR cameras, useful for fill inspection and quality control
Non-invasive Blood Vein Detection
SWIR enables non-invasive bio-signal data to see beyond the human dermis for health diagnostic or secure biometric authentication.
Printed packaging plastics or objects become transparent using SWIR cameras, useful for fill inspection or quality control.
QPD™ CMOS SWIR use-case examples
Bio-Medical/Health & Biometric
Combining visual and SWIR imaging provides information on the skin surface and below the skin into the tissue, offering a much safer medical diagnostic, health monitoring, and secure biometric solution.
ADAS & AV
Current Advanced Driver Assistance Systems and Autonomous Vehicles rely on mostly radar and visible camera, but often fail to perform to provide an accurate view and detection of driving, road, and environmental conditions compromising safety. SWIR imaging can provide accurate detection for safer, more reliable ADAS/AV systems.
Industrial & Machine Vision
The industrial automation and digitization of manufacturing is currently limited by the input image data provided by image sensor hardware.
