Abstract: An optical processor is presented for applying optical processing to a light field passing through a predetermined imaging lens unit. The optical processor comprises a pattern in the form of spaced apart regions of different optical properties. The pattern is configured to define a phase coder, and a dispersion profile coder. The phase coder affects profiles of Through Focus Modulation Transfer Function (TFMTF) for different wavelength components of the light field in accordance with a predetermined profile of an extended depth of focusing to be obtained by the imaging lens unit. The dispersion profile coder is configured in accordance with the imaging lens unit and the predetermined profile of the extended depth of focusing to provide a predetermined overlapping between said TFMTF profiles within said predetermined profile of the extended depth of focusing.

Abstract: A geothermal based, binary cycle power plant is provided, comprising: a vaporizer for vaporizing pre-heated organic motive fluid by means of geothermal steam; two organic vapor turbines operating in parallel and coupled to a common generator, each of said turbines being driven by vaporized organic motive fluid supplied to each turbine; two recuperators for heating the organic motive fluid by means of a corresponding organic vapor turbine discharge; and two condensers for condensing heat depleted motive fluid exiting said two recuperators, respectively. A geothermal steam condensate recovery system is also provided, comprising a source of geothermal steam for vaporizing a organic motive fluid and producing geothermal steam condensate, and conduit means through which geothermal steam condensate is delivered to a supply of cooling liquid used to condense the organic motive fluid, the delivered geothermal steam condensate serving as make-up liquid for evaporated cooling liquid.
