Sensors, 2014 In high frequency ultrasound imaging (HFUI), the quality of focusing is deeply related to the length of the depth of field (DOF). In this paper, a phase-inversion technique implemented by a dual-element transducer is proposed to enlarge the DOF.

Depth-sensing technology using a negative microlens array
International Journal of Optomechatronics, 2021 In this study, an optical depth-sensing system whose focus distance was equal to its object distance was constructed by using a lens with a shortened depth of field.

EyeAR: Refocusable Augmented Reality Content through Eye Measurements
Multimodal Technologies and Interaction, 2017 Augmented Reality (AR) superimposes computer graphics (CG) onto a user’s view of the real world. A key quality problem in this field is to achieve coherence between reality and CG when the user’s eyes refocus or change pupil size.

Extending AMCW lidar depth-of-field using a coded aperture [PDF]
, 2011 By augmenting a high resolution full-field Amplitude Modulated Continuous Wave lidar system with a coded aperture, we show that depth-of-field can be extended using explicit, albeit blurred, range data to determine PSF scale. Because complex domain range-
