The calibration device includes the light source which includes an ultraviolet light layer that, in operation, generates ultraviolet light, and a quantum dot layer that absorbs the ultraviolet light and, in response, generates radiation within the near infrared region at a selected intensity. The near infrared light is received at the selected intensity at the imaging device and a sensitivity of the imaging device is altered to detect the near infrared light at the selected intensity provided by the light source."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Irradiation of lead based quantum dots to generate near infrared phosphorescence as part of a compact, thin profile, on-demand calibration source","description":"A light source, calibration device and method of calibrating an imaging device is disclose.
