Detailed Description
The following description of the present invention will be made with reference to the accompanying drawings 1 to 7.
As shown in fig. 1, the stroboscope according to the first embodiment of the present invention includes a dc motor, a speed adjusting device, a polarizer, a power supply (not shown in fig. 1), L ED lamps, a collimating lens, a speed display, and further includes a viewing device, such as linearly polarized glasses or linearly polarized sheets, wherein the dc motor is used for driving the polarizer to rotate, the speed adjusting device is used for controlling the rotation speed of the dc motor, the L ED lamps are used for emitting visible light, the collimating lens is used for adjusting the divergent light emitted from the L ED lamps into parallel light, the speed display is used for displaying the rotation speed of the motor, and the power supply is used for supplying power to the motor, the speed adjusting device, the L ED lamps, and the speed display.
The collimating lens is arranged between the L ED lamp and the polaroid, when the device works, the light emitted by the L ED lamp is collimated by the collimating lens and then irradiates on the rotating polaroid, the polaroid used by the invention is a linear polaroid, so that visible light can only pass in one direction, namely, the light passing through the linear polaroid is changed into linear polarized light, and the linear polarized light irradiates on an object to be detected, such as a moving object, for example, a rotating fan blade is taken as an example in the attached drawing 1, an observer can observe the object to be detected and adjust the rotating speed of the motor through a speed adjusting device at the same time, when the rotating frequency of the linear polaroid (or the rotating frequency of the motor) is the same as the rotating frequency of the fan blade, the observer can observe a relatively static fan blade through the polarized glasses or directly through the linear polaroid.
The invention realizes the hidden stroboflash mainly on the principle that two linear polaroids are utilized, wherein one linear polaroid is a rotating polaroid, the other linear polaroid is a fixed polaroid and is used as an observation device, and light rays generate rotating linearly polarized light to irradiate a moving object after passing through the rotating polaroid. When an observer observes a moving object through the fixed linear polarizer, the observer can only see light in the direction which can be transmitted by the fixed polarizer because the linearly polarized light is reflected on the moving object, so that the light intensity is changed periodically, the stroboscopic effect can be observed, and when the rotation frequency of the rotating polarizer is the same as the frequency of the object to be measured, the phenomenon that the moving object is approximately static can be observed through the persistence of vision phenomenon.
In order to improve the observation effect, the stroboscope is further provided with an intermittent rotation control system, the intermittent rotation control system can enable the motor to have a force accumulation process, the rotation of the polaroid can be enabled to be in uneven rotation by means of the force accumulation process, the rotation of the polaroid is accelerated in the rotation process, so that the light intensity is rapidly maximized (namely when the direction of polarized light is consistent with that of the analyzer), the duty ratio of the stroboscope is reduced, and the better observation effect is achieved. As shown in fig. 2-4, the intermittent rotation control system includes a bearing 1, an outer cylinder 2, a balance spring 3, a lever 4, and a blocking device 5.
