Thus, the problem of missing data imputation can be formulated with the L1 norm as. Two waves from the same source are coherent. We report an optical interference experiment which seems to contradict our common knowledge, in that the formation of the interference pattern originates from a spatially incoherent light source. In the future, it is necessary to comprehensively consider the system performance, optimize the system structure, study more effective numerical algorithms, and realize super-resolution imaging, dynamic imaging, color imaging, etc., to obtain more excellent development space. So interference does not destroy or create energy rather it channels the flow of different amounts of energy in different directions. At some positions the waves from the two sources will arrive in phase with one another and the resulting amplitude will be $A+A = 2A$ with an intensity proportional to $(2A)^2 = 4A^2$. They result from the combination of waves that are interrelated or coherent with each other, either because they Connect and share knowledge within a single location that is structured and easy to search.
