Based on incoherent spatial light modulator telescopic experimental research of digital holographic imaging system about “White light”

At present, there are few researches about telescopic digital holography (TDH) on the combination of digital holography and telescope technology. Because this technology generally cause low phase shift accuracy and large image reconstruction distance, which will lead to low signal–noise ratio (SNR)...
