Technical field
The present invention relates to a kind of observation device, be specifically related to a kind of observation device to high-speed moving object surface quality and motion state, belong to the field of stroboscope application, alternative stroboscope, solves the problem that high-power stroboscope manufacturing cost and use cost is high.
Background technology
At present, known stroboscope is by controlling light power and exposure intensity, flashing fast, utilize the vision of eyes to stop, realize the observation to high-speed moving object surface quality and moving situation under certain condition with specific flashing rate.They have following shortcoming: one is that high-power high-frequency rate stroboscope manufacturing cost is high, expensive; Two is that stroboscope consumptive material price is high, and use cost is high.This is because stroboscope need of work generates the flash of light of characteristic frequency, luminophor flashes fast, and cause luminophor short for serviceable life, and luminophor power is larger, flashing rate is higher, and price is also higher, and therefore the manufacturing cost and use cost of stroboscope is high.These shortcomings limit the development of stroboscope industry, constrain the application of stroboscope.
Summary of the invention
In order to solve the high problem of existing high-power stroboscope manufacturing cost and use cost, the invention provides a kind of spectacle observation device with stroboscope function based on liquid crystal light valve, this observation device does not need generation to flash light source fast, can realize high-speed moving object surface quality and moving situation observation, existing stroboscope can not only be substituted, have the function of stroboscope, and than the manufacturing cost of existing stroboscope and use cost low.
The technical solution adopted for the present invention to solve the technical problems is: spectacle observation device by A, B, C tri-part form, part A is external individual luminaires, part B is glasses with liquid crystal light valves, C part is processing and control module, A is not connected with B, C, there is not control planning, B and C connects, and there is control planning.Part A and external individual luminaires, external fixing, do not need to install additional or external stroboscopic drive system, do not need to generate strobe light, luminous constant, and then luminophor long service life, and easily realize high-power output; Part B and glasses with liquid crystal light valves, component has liquid crystal light valve, back-up coat, anti-fog layer, O-ring seal, front leakproof photosphere and eyeglass band, be affixed with back-up coat before liquid crystal light valve, be affixed with anti-fog layer below, front leakproof photosphere around liquid crystal light valve and back-up coat are affixed, back-up coat and anti-fog layer are set in O-ring seal, O-ring seal connects eyeglass band, the effect of O-ring seal is, with contact near the eyes, support and fixing back-up coat, anti-fog layer, prevent side leakage light simultaneously, eyeglass band can make O-ring seal and close contact near the eyes; C part and processing and control module, component has driving circuit, single-chip microcomputer, input panel, display panel, external trigger pin and battery.Part B with the component electrical connection of C part is: the output terminal of driving circuit is connected with two liquid crystal light valves in spectacle-frame, two signal input parts of driving circuit connect the frequency control signal output pin of external trigger pin and single-chip microcomputer respectively, the output switching that driving circuit control end connects single-chip microcomputer controls pin, single-chip microcomputer connects input panel and display panel respectively, and battery is connected with single-chip microcomputer, driving circuit, input panel, display panel respectively.External individual luminaires sends high-strength light and irradiates high-speed moving object, single-chip microcomputer produces the drive singal controlling liquid crystal light valve, the break-make of liquid crystal light valve is controlled by driving circuit, make observer observe the image of clear static effect, realize the object to high-speed moving object surface quality and moving situation observation.Luminophor does not need generation frequently to flash light, without special requirements of type selecting, and low cost of manufacture; Light is constant, long service life, and the consume of observation device component is little, reduces use cost.
The invention has the beneficial effects as follows, stroboscope can be substituted by a kind of spectacle observation device, have the various functions of stroboscope, reduce observation device manufacturing cost and use cost, be beneficial to the promotion and application of observation device.
