[0042] A preparation method of a multi-channel narrow-band filtering pixel array, comprising the following steps:
[0043] Step 1, using ultraviolet photolithography and electron beam evaporation coating process on the substrate to make the metal shading grid between the overlay mark and the periodic filtering pixel unit;
[0044] In step 2, a layer of metal aluminum conductive film is made on the surface of the substrate by ultraviolet photolithography and electron beam evaporation coating as the starting substrate for electroplating;
[0045] Step 3, forming a photoresist mask by ultraviolet lithography;
[0046] Step 4, placing the substrate on which the photoresist pattern has been made into an electroplating solution pool for electroplating;
[0047] Step 5, remove the photoresist mask, and corrode the metal aluminum conductive film on the surface of the substrate to form an aluminum mask;
[0048] Step 6, using the method of ion sputtering coating to prepare the F-P ty...
