Abstract
An integral imaging method based on microscanning of a microlens array is proposed. The effects of micro-scanning on the depth resolution and the product of depth of focus and lateral resolution squared (PDLRS) of an integral imaging system are quantitatively analyzed. Calculation results show that microscanning can improve not only the depth resolution, but the PDLRS can be increased. The amount of improvement of different microscanning modes to the performance of integral imaging is closely related to the fill factor of the detector and the diffraction factor of the microlens.
