STIM (Solar Total Irradiance Monitor) can be used on sun-synchronous polar orbit weather satellites to measure the total solar irradiance. It contains three independent and identical wide view absolute radiometers. They are mounted on the satellite in an angle which ensure the sun scan over the field of view of the absolute radiometers. This measurement method doesn't need the instrument tracking the sun but the sun scan over the field of view of the absolute radiometers in each orbit cycle. The paper presents the measurement method of simulation for solar irradiance measurement and calibration by mounting the instrument on a two-axis rotation table. By controlling the rotation angle velocity of the instrument in the meridian direction being the same as that of the weather satellite's on orbit  we can measure the solar irradiance when the sun scan over the field of view of the absolute radiometers to simulate the onboard state. And we have operated the measurement with the prototype of STIM. The SIAR-1 is traceable to WRR and serves as a transfer standard. So simultaneous comparison measurements between SIAR-1 and each of the three wide view absolute radiometers are measured to provide calibration corrections to the instrument. And we have a further study at the influence of stray light to the measurement results. This paper presents the method of simulation experiment and calibration for solar irradiance measurement with Solar Total Irradiance Monitor on board.

Metallic mesh has been widely used in electromagnetic interference windows. While the duty ratio of curved mesh equals to planar mesh'  the theory of planar mesh may be applied to curved mesh according to equivalent-circuit model. So the idea that latitude lines intersect latitude lines to form isometric mesh on the concave of a sphere is put forward  and the method of fabricating the mesh by concentric optical scan is introduced. The movement parts of equipment consist of an erection turning  a horizontal dividing and a pitching dividing spindle. Firstly  a spherical substrate is fixed on the horizontal dividing spindle that has been set horizontally on the erect turning spindle  the substrate revolves around the axis of the erect spindle  the tube of object lens that is fixed on the pitching dividing spindle steps at pitching direction  and a revolving circuit of the substrate corresponds to a step of the tube. Gradually  a set of latitude lines is attained. Afterward  the substrate makes a quarter turn around the horizontal spindle  another orientation latitude lines are also gained. Thus  the isometric mesh on the concave of a spherical substrate is gained. The process comprises surface cleaning  coating photoresist  laser direct writing  development  evaporated film  dissolving photoresist and plating. The fabricated spherical mesh has a line width of 7 m and a period of 600m. Experiment shows that infrared transmission and electromagnetism shield efficiency of the metallic mesh are relatively consistent with theoretical value.
