In laser projection system, speckle reduction by wavelength and angular diversities are often treated independently. Here, it is experimentally shown that there is a clear dependency between wavelength and angular diversities. Also, speckle reduction by wavelength and angular diversities are theoretically investigated. The theoretical calculation agrees well the experimental results.
