Real-time complex amplitude reconstruction method for beam quality M2 factor measurement.
We present a real-time complex amplitude reconstruction method for determining the beam propagation ratio M2 of laser beams based on the transport of intensity equation (TIE). In this work, a synchronous acquisition system consisting of two identical CCDs is established. Once two beam intensity images at different cross-section positions along the optical axis are captured simultaneously by the...
متن کاملLaser beam complex amplitude measurement by phase diversity.
The control of the optical quality of a laser beam requires a complex amplitude measurement able to deal with strong modulus variations and potentially highly perturbed wavefronts. The method proposed here consists in an extension of phase diversity to complex amplitude measurements that is effective for highly perturbed beams. Named camelot for Complex Amplitude MEasurement by a Likelihood Opt...
متن کاملLaser beam quality measurement by micro lens array method
In the traditional laser beam quality measurement, the lens transform method is used to obtain the information of the multi spot, and can only evaluate the beam quality of a continuous or high repetition rate laser, the evaluation speed is slow and the real-time performance is poor. A micro lens array method is proposed, which samples the laser spot only once and obtains all the spot informatio...
متن کاملQuality Assurance test of the real-time beam tracking system
For radiotherapy with external beams, quality assurance (QA) of beam delivery is mandatory. Dynamical irradiation which changes parameters of beam delivery devices during the irradiation has to be assessed with a great caution. At GSI a dynamic beam delivery system, so called beam tracking system [1] was developed and integrated into the GSI therapy system [2] to irradiate moving tumours with i...
متن کاملTime-Dependent Real-Space Renormalization Group Method
In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...
