Collection: Smartphones for Near Infrared (NIR) Imaging
We have adapted the Google (Pixel 3a, 3, Nexus 5X, Nexus 5, Galaxy Nexus), Apple (iPhone 6s, 6, 5s), and Samsung Galaxy (S21 Plus, S8, S9) smartphones for multi-spectral imaging applications (visible-to-near-infrared capability). Promising applications include near infrared photography, vegetation analysis, assisted night vision, UV/IR authentication, biological detection, urban growth analysis, defeating camouflage, disaster assessment, etc.
Night Sight, introduced in Google Camera App pushes the boundaries of low-light photography with smartphone cameras. It allows exposures up to 1 minute on the Pixel 3a so you can take sharp and clear pictures of the stars in the night sky or of nighttime landscapes without any artificial light. Sample imagery here.
The imaging sensor can see from visible-to-near-infrared (VIS-NIR) spectrum. The spectral response graph below is representative of many typical CMOS sensors being used in current smartphones.
