| Abstract: | High-power laser can disturb or destroy the photoelectric detecting system (PDS). A mathematical model of the laser irradiation on the satellite-borne PDS was set up. And the damage mechanism of high-power laser to PDS was studied; the effect of the offset angle between detector and laser′s axis to the laser power illuminated on the surface of detecting element was discussed. A numeric analysis about CO2 laser irradiating HgCdTe detector was given as an example for the investigation. |
| Keywords: | Laser disturbance Laser damage Satellite-borne photoelectric detecting Laser irradiation |
