Figure 1. Architecture design and operational mechanism. a. （i）Schematic illustration showing the snake vision systems during daytime and night. (ii) Snakes focus on their target objects through the eyes during the daytime. (iii) Snakes generate a “thermal image” of prey through the pit organ for detecting infrared radiation. (iv) Schematic of the pit organ structure. b. Schematic illustration of the artificial vision perception through integrating the CMOS silicon sensors with infrared-to-visible upconverters enabling infrared visualization. c. Picture of an 8-inch silicon wafer, a zoomed view of the silicon sensor, and the optical micrograph image of the pixel region. d. (i) Schematic of the architecture and (ii) cross-sectional TEM image of CMOS sensors-integrated upconverters. e. Energy band structure diagram of upconverters without and with infrared illumination. f. Response and emission spectra of upconverters.
