The invention discloses a method and
system for continuously exciting
crystallization. The method comprises the following steps of controlling a
laser generator to emit
laser, and refracting and focusing the
laser at a specified position of a
test tube, averaging the
radius of the bubbles of the plurality of image frames acquired at the same moment in two directions to obtain the average
radius of the bubbles at the moment, calculating the average
radius of each frame of image from bubble generation to disappearance, obtaining an array of the average radius of the bubbles corresponding to time, and fitting to obtain a function r=f(t) of the average radius of the bubbles and the time, controlling a plurality of laser generators to emit at intervals or circularly emit at intervals for continuous excitation, the continuous excitation being that when the moment tx meets f(tx-tx-1)=R, the laser generators are controlled to emit, and R is smaller than the maximum radius of bubble
diffusion and is greater than the product of the
system interval excitation duration and the bubble
diffusion speed. According to the method and the
system, a plurality of lasers are fed back and controlled to continuously excite in sequence after high-speed
visual capture and fitting, and a gradually increased
supersaturation gradient is locally formed in the solution, so that the discovery of a new
crystal form is facilitated.
