Claim Text:
1. An optical imaging system, comprising: a spatial light modulator (SLM) that receives light of a first wavelength and light of a second wavelength, and outputs an image light of the first wavelength and an image light of the second wavelength, the first and second wavelengths being different from each other; a first dichroic beam splitter that receives the image light of the first and second wavelengths from the SLM, and reflects the image light of the first wavelength in a first direction and transmits the image light of the second wavelength in a second direction; a first mirror that receives the image light of the first wavelength from the first dichroic beam splitter and reflects the image light of the first wavelength at a first angle; a second mirror that receives the image light of the second wavelength from the first dichroic beam splitter and reflects the image light of the second wavelength at a second angle; and a second dichroic beam splitter that receives the image light of the first wavelength from the first mirror and the image light of the second wavelength from the second mirror, and recombines the image light of the first and second wavelengths to produce an overlap image.
