  The in­spec­tion and track­ing of laser-in­duced dam­ages of op­tics play a sig­nif­i­cant role in high-power laser sys­tems. Laser-in­duced de­fects or flaws on the sur­faces of op­tics are pre­sented in im­ages ac­quired by spe­cific charge cou­pled de­vices (CCDs), hence the iden­ti­fi­ca­tion of de­fects from laser dam­age im­ages is es­sen­tial. De­spite a great ef­fort we have made to im­prove the imag­ing re­sults, the de­fect iden­ti­fi­ca­tion is a chal­leng­ing task. The pro­posed re­search fo­cuses on the pre-pro­cess­ing of laser dam­age im­ages, which as­sists iden­ti­fy­ing optic de­fects. We for­mu­late the image pre-pro­cess­ing as a total vari­a­tion (TV) based image re­con­struc­tion prob­lem, and fur­ther de­velop an al­ter­nat­ing di­rec­tion method of mul­ti­pli­ers (ADMM) al­go­rithm to solve it. The use of TV reg­u­lar­iza­tion makes the pre-processed image sharper by pre­serv­ing the edges or bound­aries more ac­cu­rately. Ex­per­i­men­tal re­sults demon­strate the ef­fec­tive­ness of this method.

  Tango pro­vides the Tango de­vice server ob­ject model(TDSOM), whose basic idea is to treat each de­vice as an ob­ject. The TDSOM can be di­vided into 4 basic el­e­ments, in­clud­ing the de­vice, the server, the data­base and the ap­pli­ca­tion pro­gram­mers in­ter­face. On the basis of the TDSOM, we de­sign a cen­tral­ized plat­form for soft­ware de­vice man­age­ment, named Vi­su­alDM, pro­vid­ing stan­dard servers and client man­age­ment soft­ware. Thus the func­tion­al­ity of Vi­su­alDM are mutli-folds: 1) dy­nam­i­cally defin­ing or con­fig­ur­ing the com­po­si­tion of a de­vice con­tainer at run-time; 2) vi­su­al­iza­tion of re­mote de­vice man­age­ment based on sys­tem sched­ul­ing model; 3) re­mote de­ploy­ment and up­date of soft­ware de­vices; 4) reg­is­ter­ing, lo­gout­ing, start­ing and stop­ping de­vices. In this paper, plat­form com­po­si­tions, mod­ule func­tion­al­i­ties, the de­sign con­cepts are dis­cussed. The plat­form is ap­plied in com­puter in­te­grated con­trol sys­tems of SG fa­cil­i­ties.
