Extended Data Fig. 9: Single-pixel visible and infrared imaging measurement.

(a, d; b, e) Optical photograph of front and side view of two imaging scenes. (c, f) Results of two imaging operating at room temperature, corresponding to the scenes a and d, respectively. The incandescent lamp is used as the infrared radiation source (broad emission ranges from visible to near-infrared), and the LED surface light source with a university logo is used as the visible light radiation source. The target is imaged by the two-dimensional scanning imaging device. The band of incident light can be changed by setting visible light filter (850 nm high pass). In the first test scene, the incandescent lamp and LED were imaged at the same time, where the images of the both are very legible. (panel c). In the second test scene, the incandescent lamp was covered with a visible light filter, only the near-infrared (λ ≥ 850 nm) light can pass the filter. The imaging of the logo (visible) and the incandescent lamp that filters out the visible light were also both realized (panel f). The results indicated that the response wave band of the detector covers both visible and near infrared.
