We propose an optical scanning holography (OSH) for optical reconstruction with equal scale magnification or demagnification ratio along the transverse and longitudinal directions when the magnification or demagnification ratio of the hologram is priori known. First, we review the principles of OSH. Second, we propose an equal scale OSH that encodes a 3D distribution of a 3D scene with a scanning beam pattern that is formed by the superposition of two spherical waves with the same curvature direction. The hologram recorded by the equal scale OSH reconstructs the 3D scene with equal scale magnification or demagnification along the transverse and longitudinal directions. Finally, we provide simulation and experiment results to illustrate and clarify the proposed idea.

Institute for Pain Medicine, Chaim Sheba Medical Center, Tel Hashomer, Israel.
Background: Nonspecific low back pain (LBP) has become a significant worldwide public health problem. It is estimated that 84% of people present it at some point in their lives, in which 23% experience its chronic form, negatively affecting their daily lives. Because pain management tool that doesn't require a firm diagnosis, the development of a device, as SOLIO Alfa Cure Plus, that emanates low level laser therapy, radio frequency and heat with the goal of easing chronic back pain was highly expected.

Shelf-Stable Formulation for Scalable Laboratory and Field-Based Production of Biocement.
ACS Appl Mater Interfaces
January 2025
Materials and Manufacturing Directorate, Air Force Research Laboratory, Wright-Patterson AFB, Ohio 45433, United States.
Biocement is an environmentally friendly alternative to traditional cement that is produced via microbially induced calcium carbonate precipitation (MICP) and has great potential to mitigate the environmental harms of cement and concrete use. Current production requires on-site bacterial cultivation and the application of live culture to target materials, lacking the convenience of stable formulas that enable broad adoption and application by nonscientific professionals. Here, we report the development of a dry shelf-stable formulation of , the model organism for biocement production.
