If we try to measure the backward optical diffraction radiation (BODR) of high energy electrons from a conductive slit or a semi-infinite plate, the electron beam will pass through the bending magnet (BM) or steering magnet (SM) or magnet lenses before striking the target. The synchrotron radiation (SR) from these magnets can then obscure the BODR measurements. Analysis of the SR properties from these magnets is presented. A model based on the modified Lenar-Wikherd potentials was created, and the SR angular distribution from relativistic electrons in BM and SM for different conditions of radiation in the optical region was calculated. Analysis shows that for the parameters of the KEK ATF extraction line, the SR intensity exceeds that of the backward optical transition radiation (BOTR) from the conducting targets, and it is much larger than the BODR intensity. The SR intensity from the SMs depends on its tuning and may be comparable to BOTR. Thus, the problem of separating of BODR and SR in the BODR measurements is important. Two methods of resolving this problem are suggested.
