The invention discloses a demonstrating device for a light oscillography vector synthesis graph line, comprising an oscillator composed of two orthogonal coils, a magnet generating two orthogonal magnetic fields, a receiving screen and an image acquiring and processing system. Light (laser beam) is projected on the receiving screen after being reflected by a plane mirror at the center of the oscillator, the oscillator can realize two-dimensional surface oscillation under the action of an electric excitation signal, and a feature graph of the electric signal for exciting the oscillator to oscillate can be obtained through processing and analyzing light spot information on the receiving screen. A vector synthesis track graph of a photoelectric signal can be achieved through the two-dimensional surface oscillation, and the demonstrating device is simple and feasible in structure and strong in operability; no complex optical system is needed, therefore, the cost is low; in addition, the demonstrating device not only can be used for light vector synthesis demonstration, but also can be used as an ammeter.
Description
technical field [0001] The invention relates to the technical field of photoelectric teaching instruments, in particular to a light oscillometric vector synthesis graph line demonstration device. Background technique [0002] At present, in the photoelectric teaching, the demonstration technology of Lissajous figures mainly uses light oscilloscope, which is an instrument that uses light deflection and light sensitivity to record the change process of one or more frequencies within a certain range of electricity with time. [0003] However, the inventors have found that existing demonstration techniques have the following disadvantages: [0004] The demonstration technology using a light oscilloscope is not suitable for light recording with a scale and rated error, and cannot realize the X-Y recording of light, and cannot use a light recording oscilloscope with a non-electric drive or cathode ray oscilloscope as a measurement mechanism. Contents of the invention [0005] T...
