Abstract: A digital communication method over an optical channel. Bob modulates a coherent optical signal with a random envelope phase ?r, known to him and not to Alice, and transmits the modulated coherent optical signal (envelope) over the optical channel to Alice. Alice further modulates the envelope with a key phase ?k, based on a secret key and a selected modulation scheme, to create a cipher envelope, and sends the cipher envelope towards Bob along the optical channel. Bob then demodulates a received version of the cipher envelope by removing the random envelope phase ?r (known to Bob) and then measures the phase of the resulting demodulated coherent optical signal with the coherent detector to extract, to within a certain margin of error, the key phase ?k, from which Alice's secret key can be decoded. Bob then uses the secret key for encrypting messages sent to Alice over any digital network.

Abstract: A reduced footprint collimator device to focus light beam over length of optical path for use in an optical cytometry device or other optical instrument where a focused beam of light is passed through a test medium and then sampled by a photomultiplier or multiple photomultipliers for analysis. This device provides alignment and focus of that beam and collimation along the entire beam path. In addition in order to reduce the overall footprint of the beam path this device uses a precision coated prism to redirect the optical path perpendicular to the entering optical beam. The reduced footprint collimator device to focus light beam over length of optical path generally includes a reduced footprint 90 degree collimator which allows light beam collimation, beam path alignment, selectable beam focal distance, and reduces stray light reflections all in a minimal footprint.an These features allows for a smaller overall instrument design.
