OPERATION GLASSPANE: Laser Microphone Construction & Deployment // Acoustic Surveillance Through Reflective Surfaces

OPERATION GLASSPANE: The Complete Guide to Optical Eavesdropping

Listen to the silence.

Every window is a microphone. Every reflective surface is a vulnerability.

In OPERATION GLASSPANE, we dismantle the theory behind laser microphones and provide you with the practical roadmap to build and deploy your own optical surveillance system. This guide bridges the gap between high-end spy fiction and garage-level engineering, allowing you to intercept sound waves through barriers that were previously considered impenetrable to the naked ear.

This is not just a science experiment; it is a comprehensive study in the physics of sound and the manipulation of light.

WHAT’S INSIDE:

• The Physics of Reflection: Understanding how minute acoustic vibrations modulate a reflected laser beam (Interferometry & Doppler effect).
• Component Sourcing: A precise shopping list. From budget-friendly diodes to professional-grade optical sensors, learn exactly what hardware you need and why.
• The Build Guide: Step-by-step schematics for constructing the receiver unit, the amplifier circuit, and the aiming assembly.
• Signal Processing: How to capture the noise and isolate the voice. Techniques for cleaning up the signal using software to turn raw jitter into intelligible audio.
• Deployment Tactics: The practical side of fieldcraft. Selecting the target, managing angles, counteracting environmental noise, and maintaining distance.

WHO IS THIS FOR? This is for hardware hackers, security researchers, electronics hobbyists, and privacy advocates who want to understand the physical layer of audio surveillance. To get the most out of this guide, you should have basic soldering skills and familiarity with simple circuitry.
