Review maps the future of bioinspired adaptive optical imaging

A review published March 30, 2026 in Opto-Electronics Plus says imaging systems are moving from fixed, camera-like optics toward adaptable designs inspired by the human eye and insect compound eyes. The work highlights technical routes such as liquid lenses and tunable ommatidia, while flagging integration, reliability and control as the main hurdles to real-world use.

Why it matters: - Bioinspired adaptive optical imaging could give cameras and sensors the ability to adjust focus, field of view and lighting response the way living eyes do. - The shift matters for autonomous driving, robotics and precision medicine, where machines need faster perception and better preprocessing than conventional rigid optics can provide.

What happened: - A review article titled “Bioinspired adaptive optical imaging technology” was published online on March 30, 2026 in Volume 2 of Opto-Electronics Plus. - The review was led by Dr. Wang Qionghua, professor and doctoral supervisor at Beihang University in China. - The article surveys two main research directions: human eye-inspired adaptive imaging and compound eye-inspired adaptive imaging.

The details: - Human eye-inspired systems aim to copy the focusing function of the crystalline lens and the aperture control of the pupil. - Liquid lenses use voltage to reshape a liquid droplet and achieve millisecond-level focusing. - Liquid crystal lenses use an electric field to change molecular alignment and refractive index, with no moving parts and easier array integration. - Dielectric elastomer lenses use high voltage to deform an elastic film, creating large deformation with a muscle-like actuation method. - The review says these approaches support smartphone cameras, augmented reality displays and high-performance bioinspired zoom systems. - Compound eye-inspired systems use many ommatidia to deliver a wide field of view, high sensitivity and strong motion detection. - Early systems such as TOMBO used planar microlens arrays for parallel imaging. - The AWARE series used a “primary objective lens + micro-camera array” setup to reach billion-pixel ultra-wide field-of-view imaging. - A newer approach places tunable parts such as liquid lenses into each ommatidium so the system can focus by target distance and adjust aperture shape for changing light. - The review also points to bird foveal imaging, snake infrared thermal imaging, and mantis shrimp polarization and multispectral vision as additional design models. - The article frames the field as moving from single-parameter imitation toward multi-modal and multi-functional systems.

Between the lines: - The review suggests the field is leaving simple biomimicry behind and moving toward adaptive machines that can sense and respond in real time. - The biggest technical hurdle is not inspiration. It is making dense, reliable systems that can coordinate multiple parameters at once. - The future likely depends on combining metasurfaces, new optoelectronic materials, soft adaptive materials and neuromorphic architectures that blend sensing, storage and computation.

What's next: - The review says future vision systems will likely act less like image recorders and more like intelligent perception units. - Expected applications include autonomous driving, robotics and precision medicine. - The broader research agenda will focus on integration density, reliability and multi-parameter cooperative control.

The bottom line: - Bioinspired adaptive optical imaging is moving toward machines with more “living” eyes, but practical deployment still hinges on engineering systems that are compact, durable and smart enough to adapt on the fly. - The paper’s DOI is 10.67704/oep.2026.260003.
