The Walt Disney Company has maintained an aggressive approach to brand management for nearly a century. With the acquisition of a number of highly reputable companies, this aggression has become unignorable within the media industry. At the same time, Disney has embraced digital expansionism, culminating with the launch of its own on-demand streaming service, Disney+, in late 2019.

Design: Acoustic micro-tapping OCE was performed on normal and CXL human donor cornea in an ex vivo laboratory study.
Subjects: Normal human donor cornea (n = 22) divided into 4 subgroups.
Purpose: To compare noncontact acoustic microtapping (AμT) OCT elastography (OCE) with destructive mechanical tests to confirm corneal elastic anisotropy.
Design: Ex vivo laboratory study with noncontact AμT-OCE followed by mechanical rheometry and extensometry.
Participants: Inflated cornea of whole-globe porcine eyes (n = 9).
Skin broadly protects the human body from undesired factors such as ultraviolet radiation and abrasion and helps conserve body temperature and hydration. Skin's elasticity and its level of anisotropy are key to its aesthetics and function. Currently, however, treatment success is often speculative and subjective, and is rarely based on skin's elastic properties because there is no fast and accurate non-contact method for imaging of skin's elasticity.

To enable quantitative clinical spectroscopy, the fundamental issues of wavelength-dependent fluence variations and inter-wavelength motion must be overcome. Here we propose a real-time, spectroscopic photoacoustic/ultrasound (PAUS) imaging approach using a compact, 1-kHz rate wavelength-tunable laser.
