The invention discloses a deep Q neural network anti-interference model and an intelligent anti-interference algorithm. A pair of emitting end and receiving end is a user, communication with the useris carried out, user communication is interfered by one or multiple jammers, the spectrum waterfall map of the receiving end is used as an input state of learning, and frequency domain and time domaincharacteristics of the interference are calculated. The algorithm comprises steps that firstly, a Q-value table corresponding to fitting is obtained through the deep Q neural network; secondly, a strategy is selected by the user according to the probability, training is carried out based on a return value of the strategy and the next environmental state, and the network weight and frequency selection strategy are updated; when the maximum number of cycles is reached, the algorithm ends. The model is advantaged in that the model is complete, the physical meaning is clear, the design algorithmis reasonable and effective, and the anti-interference scene based on the deep reinforcement learning algorithm can be excellently described.

Laser lines at 635 nm or longer (ideally 647 nm) are preferred for red, giving energy-efficient, bright, rapid-motion images with rich, full film-comparable colors. Green and blue lines are used too—and cyan retained for best color mixing, an extra light-power boost, and aid in speckle suppression. Speckle is suppressed through beam-path displacement—by deflecting the beam during projection, thereby avoiding both absorption and diffusion of the beam while preserving pseudocollimation (noncrossing rays). The latter in turn is important to infinite sharpness. Path displacement is achieved by scanning the beam on the liquid-crystal valves (LCLVs), which also provides several enhancements—in energy efficiency, brightness, contrast, beam uniformity (by suppressing both laser-mode ripple and artifacts), and convenient beam-turning to transfer the beam between apparatus tiers. Preferably deflection is performed by a mirror mounted on a galvanometer or motor for rotary oscillation; images are written incrementally on successive portions of the LCLV control stage (either optical or electronic) while the laser “reading beam” is synchronized on the output stage. The beam is shaped, with very little energy loss to masking, into a shallow cross-section which is shifted on the viewing screen as well as the LCLVs. Beam-splitter/analyzer cubes are preferred over polarizing sheets. Spatial modulation provided by an LCLV and maintained by pseudocollimation enables imaging on irregular projection media with portions at distinctly differing distances from the projector—including domes, sculptures, monuments, buildings; waterfalls, sprays, fog, clouds, ice; scrims and other stage structures; trees and other foliage; land and rock surfaces; and even assemblages of living creatures including people.

A laminar flow waterfall in the form of a single or multiple streams of water, each exiting from a nozzle in the top edge of a spa. The laminar water stream is created by a venturi nozzle located in a plenum chamber. The inlet side of the nozzle has a cover with a plurality of small holes forcing the water flow to enter the nozzle as laminar flow. A flow divider inside the venturi nozzle, from the inlet to the restriction of the nozzle, maintains the flow laminar through the nozzle. Light is injected into the flow divider at the inlet and is carried by the flow divider to be injected into the water flow at the restriction of the nozzle.
