摘要
Provided are a full-day imaging detector with a multi-functional window, and a method for preparing same. The full-day imaging detector comprises a multi-functional window (1) and a detection portion (2). The multi-functional window (1) comprises a micro-lens array (3), a window body (4) and an optical filter array (5), wherein the micro-lens array (3) is integrated on an upper surface of the window body (4), a top surface of each micro-lens unit is of a spherical crown structure, the projection of the spherical crown is square from a top view, and the square projections of spherical crowns of adjacent micro-lens units from the top view are connected; the optical filter array (5) is plated on a lower surface of the window body (4); and the optical filter array (5) comprises four types of optical filters, including three types of band-pass optical filters of single-color visible light in combination with an infrared waveband, and an infrared optical filter. The detection portion (2) is constituted of a pixel unit array, wherein each pixel unit comprises four types of sub-pixel units, and the four types of sub-pixel units directly face the four types of optical filters in a one-to-one correspondence mode. Further provided are a method for preparing a micro-lens array and a detection method for a detector. Full-day detection can be realized.
