Searches for Laser Signals

We develop optical instruments and spectroscopic algorithms to detect laser pulses from space.  Instruments include telescopes equipped with high-dispersion prisms, high-speed cameras, and high resolution spectrometers.

A pair of telescopes validates laser pulses with sub-second time resolution.

Our optics distinguish lasers from stars, planets, and solar reflections off satellites, and can detect direct laser beams and glints, including from beyond Earth (SETI).

Lasers provide:

10 Gbit/sec bandwidth, private narrow beams, compact beam launching/sensing, robust encryption, and light-speed.Global internet, environmental remote sensing, GPS positions, market latency of 19 millisec, and national security data.

Light-speed video links to the Moon, Mars, and beyond, and perhaps among civilizations in the Milky Way Galaxy, including Alpha Centauri and Proxima Centauri.

The Double Telescope: Schmidt and Refractor

We detect and confirm lasers with a double-telescope, each having a wedge prism over the front to produce spectra

The Wedge Prism

The wedge prism are made of flint-type glass to produce spectra of each point in the field of view. The two prism surfaces are flat to a 1/4 of the wavelength of light.
