We propose an optical configuration for incoherent digital holography with aperture control, constructed solely with transmissive optical elements. This configuration enhances light utilization efficiency twofold compared to our previous design. We have verified that aperture control increases the hologram signal amplitude and the contrast ratio of the reconstructed image.
