Eritek Inc

Provides comprehensive services in the optical sciences, specializing in optical beam propagation, custom design, and modeling.

• Free Space Optical Communications

  Designs, integrates, and tests custom Free Space Optical Communications (FSOC) solutions for terrestrial and ground-to-space applications, including link budget calculations, atmospheric propagation analysis, and fade-tolerant optical modem designs.

• Optics Design

  Develops specialized optical and mechanical configurations using design tools such as Zemax, Matlab, and SolidWorks.

• Optical Power Beaming

  Designs, fabricates, and operates systems in the 1550 um band to transmit optical power over several hundred meters, providing power to untethered devices.

• Optical Scatter Models

  Develops and validates MATLAB-based atmospheric and hard surface scatter models to simulate optical beam propagation under diverse environmental conditions.

  • Atmospheric Scatter Models

    Generates radiometrically accurate frames representing Mie and Rayleigh scatter, accounting for light polarization, 3D sensor placement, and specific atmospheric aerosol concentrations.

  • Hard Surface Scatter Models

    Calculates combined specular and lambertian scatter off structural surfaces, incorporating direct and diffuse background solar light calculations.

Offers planning, testing, and deployment of robust radio frequency communication systems for terrestrial and other applications.
