What advanced technology can humans use to photograph the earth?

There are five kinds of high-tech instruments on the satellite, among which the largest and most critical instrument is an infrared imaging radiation combination, also known as visible infrared imaging radiation module. This is a high-tech scanning radiometer, which can collect visible infrared images and calculate the measured values of land, atmosphere and ocean. The earth in the photo is very clear, as if it were presented to people in three dimensions, and both the color and the details on the earth are very eye-catching.
