1Real-time noise-free inline self-interference incoherent digital holography with temporal geometric phase multiplexing显示文摘In this paper,we propose a real-time incoherent digital holographic(IDH)recording system free from bias and twin-image noises.A motionless three-step polarization-encoded phase-shifter operating at 99 Hz is realized with two electrically controllable birefringence-mode liquid crystal cells operating in tandem with a geometric phase lens and polarizers.Based on the proposed optical configuration,a coaxial straight-line self-interference IDH recording system is devised.Notably,the elimination of bias and twin-image noise from three phase-shifted images is demonstrated as a proof of concept.Moreover,complex-valued holographic video acquisitions with a resolution greater than 20 megapixels are demonstrated,with an effective acquisition frequency of33 Hz.KIHONG CHOI JAE-WON LEE JUNGYEOP SHIN KEEHOON HONG JOONGKI PARK HAK-RIN KIM 2023Photonics Research2023,11,6:0
