This image seems to be following me like the 44's do.🧐

very cool image AWE = A VV E ?

A novel two-dimensional optical thermal ratchet has been implemented with holographic optical trapping arrays structured as the "Fibonacci spiral" for diffusing colloidal particles. Periodically rotating the optical trapping array by an angle in a three-step cycle yields a two-dimensional time-varying optical landscape that acts either as (1) a deterministic pump when traps are closely dispersed in space, whose induced radial and azimuthal fluxes can be quantitatively mapped out according to the geometry of Fibonacci spiral, or else as (2) an optical thermal ratchet when traps are widely dispersed, whose transport property depends on the competition between the temporal evolution in optical landscapes and Brownian particles' diffusivity. The Fibonacci ratchet displays independent flux reversals in both the radial and azimuthal directions as a function of the cycle frequency and the inter-trap separation

Figure 1. Schematic representation of a typical holographic optical tweezer array. A collimated laser beam incident from the left is shaped by a diffractive optical element (DOE), transferred to an objective lens' back aperture (B) by lenses L1 and L2 and focused into a trapping array. OP{}^{ast} denotes the plane conjugate to the trapping plane. The point B{}^{ast}is conjugate to B. The phase pattern on the lower left (black regions shift the phase by pi radians) produced the traps shown in the lower right filled with 1~mathrm{upmu}mathrm{m} diameter silica spheres suspended in water.
