Micro-nano scale hetrodyne wavelength division demultiplexing for microscopy/tomography having parallel data acquisition

An optical image detector comprising:

• (a) a tunable K-vector selector;
• (b) optical signal input means for directing an optical image at said tunable K-vector selector;
• (c) image K-wave vector modulation inducing means for causing said optical image to oscillate and modulate said K-vector selector;
• (d) tuning control means for applying a fluctuating hetrodyne signal to said K-vector selector having a phase locked template with respect to oscillation of said optical image for causing said tunable K-vector selector to hetrodyne and correlate a phase locked matching template with light emitted from said optical image;
• (e), time integrating detector means for time integrating output signals from said tunable K-vector selector;
• and.
• (f) interconnect means for interconnecting point sources of said optical image detected by said K-vector selector with corresponding imaging points upon said time integrating detector means.

Method of measuring a wave front of light of an incoming light beam comprising the steps of:

• (a) providing a K-vector tunable Bragg cell;
• (b) directing said incoming light beam at said Bragg cell;
• and
• (c) measuring an intensity pattern of light emanating from said K-vector Bragg cell for indicating variations in slope of said wave front tuned at a selected wavelength.
