    Abstract: A method includes: controlling a first layer of a panel so that first electrical signals generated based on the first driving signal are applied to first cells of the first layer, and light incident on the first layer is modulated into a first modulated light according to the first electrical signals; and controlling a second layer of the panel so that second electrical signals generated based on the second driving signal are applied to second cells of the second layer, and the first modulated light received from the first layer is modulated into a second modulated light according to the second electrical signals. A modulation resolution of the second modulated light output from the second layer is greater than that of the first modulated light due to at least two second cells of the second layer that modulate light modulated by one first cell of the first layer.

    Abstract: A method and apparatus are provided to generate tomography images that performs the method. The apparatus and method are configured to determine a basis pattern from modulated phases of incident rays from a spatial light modulator according to a pattern of arranged pixels. The apparatus and method are further configured to perform spatial shift modulation shifting an arrangement of the pixels vertically or horizontally with respect to the basis pattern to obtain shift patterns of the basis pattern. The apparatus and method are configured to generate tomography images for the basis pattern and the shift patterns using spectrum signals of rays obtained from the incident rays passing through the spatial light modulator and entering a subject. The apparatus and method are configured to select a pattern that generates a clearest tomography image of the subject based on the generated tomography images.
