Embodiment Construction
[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0015] The invention provides a generalized m-bonacci zone plate, which is composed of transparent annular zones and opaque annular zones alternately arranged according to the arrangement rule of the generalized m-bonacci binary aperiodic sequence. The zone plate of this embodiment forms a corresponding generalized m-bonacci binary aperiodic sequence according to the recurrence rule of the generalized m-bonacci number, and forms a corresponding generalized m-bonacci binary aperiodic sequence through the transmittance function The wave zone plate. The zone plate described in this embodiment has two...

The invention discloses a generalized m-bonacci zone plate and construction method thereof. The zone plate is formed by transparent girdle and non-transparent girdle arranged in an alternating manneraccording to an arrangement rule of a generalized m-bonacci binary sequence. The construction method includes constructing a generalized m-bonacci number, generating a generalized m-bonacci binary aperiodic sequence according to the recurrence rule of the generalized m-bonacci number, and then obtaining the generalized m-bonacci binary aperiodic sequence based zone plate through combination with acorresponding transmittance function. The zone plate provided by the invention has two prime focuses having equal intensity. The axial positions of the two prime focuses meet a generalized precious division ratio, so that the ratio of distances from the two prime focuses to the zone plate meets a plurality of proportion relations. Therefore, the zone plate can image on two designated planes, realizes laser three-dimensional space parallel operation and realize multi-plane simultaneous particle capturing in three-dimensional photographing technology.
Description
technical field [0001] The invention relates to optoelectronic technology, in particular to a generalized m-bonacci zone plate and its construction method. Background technique [0002] Aperiodic zone plates are widely used in many scientific research fields. For example, the Fibonacci zone plate can produce two focal points with equal intensity in the axial direction, and the distance between the two focal points and the zone plate satisfies the golden section ratio. Capture particles. The zone plate or photon sieve generated based on the generalized Fibonacci sequence can be used as a special diffractive optical element in imaging and lithography. The generalized golden ratio includes the golden ratio. The two high-intensity focal points produced by the Fibonacci Kano prism can perform clear imaging, and the positions of these two focal points meet the golden ratio. The positions of the two focal points produced by the generalized Fibonacci zone plate satisfy several s...
