We have heard of effects from microwave radiation,  but what about Infra-red lasers emitting from cell phones?

Many believe it is for facial recognition, Note that one part of the video shows Apple AirPods emitting the same Infra-red lasers.

The author from Europe encourages people to film this with their own video cameras that can film in night vision mode.

Description

BELAGO1.2 is the latest variant in the ams OSRAM dot projector family offering higher dot count for improved resolution in 3D sensing. It is pin compatible with older Belago variants and offering higher maximum power in addition to 3x higher dot density. BELAGO1.2 is following the high-quality standards of ams OSRAM offering a reliable solution for demanding environments.

The compact dot-projector for stereoscopic imaging is optimized for active stereo vision and structured light systems. With 15k dots in a pseudo-random pattern high-contrast and high-density dot pattern is achieved. The small footprint allows for an easy integration in mobile platforms and offers the the perfect power/size ratio. The high optical efficiency as well as the high VCSEL efficiency contribute to a low power consumption on system level.

With the built-in eye safety interlock feature it facilitates the implementation on system level.

3D sensing, 3D imaging, Machine Vision and Access Control are the main applications.

Blue Light 

Blue light for Optogenetics can also come from sources such as your phone screen…
Here’s an overview of “Light‑mediated control of gene expression in mammalian cells” by Yamada et al. (2020):
—
1. Why this matters
Controlling when and where genes are expressed in mammalian cells is key for understanding gene function, tissue development, disease mechanisms, and therapeutic interventions. Traditional systems (e.g., Tet‑ON/OFF, Gal4/UAS) depend on chemicals or promoters, which lack tight spatiotemporal control—they’re slow, diffuse, or have residual effects.
—
2. The optogenetic solution
Optogenetics uses genetically encoded, light-responsive proteins to regulate gene expression with precise timing and targeting. The paper categorizes methods by wavelength:
A. Blue‑light systems
Cry2/CIB1: Upon blue light, these plant-derived proteins dimerize, activating transcription—used to combine with Tet regulators (PA‑Tet‑ON/OFF) for switchable control by blue light plus doxycycline for even finer tuning.
LOV‑based switches (e.g., TULIPs, iLID): These involve light-induced protein interactions that regulate gene circuits.
VVD‑derived “LightOn” / “Magnets”: Light‑triggered homo‑ or hetero‑dimerization of small LOV domains enables robust and reversible gene activation in cultured cells and mice.
These systems offer rapid on/off switching and can be tightly localized to individual cells or subcellular regions.
B. Red / near‑infrared (NIR) systems
PhyB/PIFs (plant phytochromes): Dimerize under red light, reversed by far-red light; require exogenous chromophores (PCB), although biosynthesis is being developed.
BphP1/PpsR2 (Q‑PAS1): Uses endogenous biliverdin and NIR light to enable deeper tissue penetration and reversible control—great for in vivo applications.
—
3. Integration into gene circuits
These light switches can couple with:
Tet systems (PA‑Tet‑ON/OFF) combining light and drug control
Gal4/UAS, TALE- or dCas9-based activators—for targeting either exogenous or endogenous genes .
—
4. Performance characteristics
Speed: Many optogenetic dimerizers act within seconds; deactivation kinetics vary by system.
Dynamic range: Achieve high fold-activation with low background expression.
Tunable: Light intensity, duration, and wavelength modulate expression levels.
Spatial precision: With focused light or optical fibers, control gene expression in single cells or subregions—even deep tissues.
Multiplexing potential: Combining blue‑ and red/NIR-responsive systems allows independent control over multiple genes .
—
5. Challenges and future directions
Chromophore delivery: Blue-light systems use endogenous flavins. Red/NIR systems may need external chromophores or engineered biosynthesis .
Tissue penetration: NIR light and upconversion nanoparticles help target deep tissues .
System integration: Moving from cells to whole organisms requires further miniaturization (e.g., wireless μLEDs) .
Endogenous gene targeting: Light-inducible TALE/dCas9 (“LITE” and similar systems) are advancing precise control of native gene expression .
—
Summary
Yamada et al. highlight how optogenetic gene expression control systems, responsive to blue and red/NIR light, offer unprecedented speed, precision, and versatility compared to traditional methods. These systems allow reversible, tunable, and spatially confined gene manipulation, with exciting implications for basic research, synthetic biology, and therapeutic strategies.
