#New detection method turns silicon cameras into mid-infrared detectors
“#New detection method turns silicon cameras into mid-infrared detectors” Artistic rendering of the principle of non-degenerate two-photon absorption (NTA) for the detection of mid-infrared (MIR) by a silicon-based camera. In this detection technique, the sensor is illuminated directly by the MIR light beam, while a second, near-infrared (NIR) beam is also incident on the sensor….
