Abstract
The invention discloses a kind of polychrome luminous point flicker fusion critical frequency test devices, it is characterised in that: it includes an inspection section, a display and an instrument base；The present invention utilizes computer software and hardware technology, the shining point of different colours is alternately presented in LED tri coloured lantern in controlled observation cylinder, detected subject utilizes the operation button on instrument, oneself adjust the time of each color luminous point presentation, its flicker frequency is controlled, until it achievees the effect that fusion, two kinds or sees the luminous point not flashed, the color of the luminous point is heterogeneous light secondary colour, and the flicker frequency of this time point is exactly polychrome coloured light fusion threshold；The present invention realizes the measurement of polychrome coloured light fusion threshold range for the first time, measures the influence that the quantity of different color combinations, the different order of different combinations of colors and color merges coloured light, analyzes the reciprocation between each factor.
Description
Technical field
The present invention relates to polychrome luminous points to merge the field of test technology, critical more particularly to a kind of polychrome luminous point flicker fusion
Frequency testing device.
Background technique
The information about the external world 80% that the mankind obtain is provided by vision, and wherein color is visual information
Important carrier.The one kind of flicker fusion as visual phenomenon in general psychology to relate to more.However current research shape
Condition is: people have flicker fusion preliminary understanding, can clearly measure people by the overlooking frequency recorder of flicker fusion
Flicker fusion time threshold, meanwhile, also have more deep exploration for the neuromechanism of color perception；But for difference
Coloured light alternately flashes and studies summary of the invention at few people the case where continuous single secondary color by consciousness.
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of surveys of polychrome luminous point flicker fusion critical frequency
Trial assembly is set.
Summary of the invention
A kind of polychrome luminous point flicker fusion critical frequency test device, it is characterised in that: it includes an inspection section, a display
Device and an instrument base；The LED tri coloured lantern of capable of emitting red, blue, green three colors is provided among the inspection section bottom,
Surrounding inside inspection section close to LED tri coloured lantern is provided with intensity adjustable LED white light source；Setting in the instrument base
There are power supply and control circuit, the instrument base surface is provided with operation button and instrument switch, charging interface and instrument state
Indicator light, instrument state indicator light include a power supply indicator, a charging indicator light, a bluetooth connection indicator light；The LED tri-
Colored lights, LED white light source, instrument key, instrument switch, charging interface and instrument state indicator light are all connected with control circuit
It connects；The display and instrument base use Bluetooth communication.
The present invention utilizes computer software and hardware technology, and different face are alternately presented in the LED tri coloured lantern in controlled observation cylinder
The shining point of color, detected subject oneself adjust the time of each color luminous point presentation using the operation button on instrument,
Its flicker frequency is controlled, until it achievees the effect that fusion, two kinds or sees the luminous point not flashed, the luminous point
Color is heterogeneous light secondary colour, and the flicker frequency of this time point is exactly polychrome coloured light fusion threshold.
Compared with prior art, the beneficial effects of the present invention are:
(1) present invention realizes the measurement of polychrome coloured light fusion threshold range for the first time.
(2) coloured light fusion frequency under the quantity of the combination of different colours coloured light, different order and different colors can be measured
Rate.
Detailed description of the invention
Fig. 1 are as follows: schematic structural view of the invention.
Fig. 2 are as follows: flow chart of the present invention.
Specific embodiment
The following further describes the present invention with reference to the drawings.
