System is fixed on endoscope's platform and is connected on eyepiece rear end.Aperture light source is respectively at 5 different azimuth (diverse location of visual field)
Place, measure endoscope's eyepiece exit luminous flux.Take off luminous flux measurement system and endoscope, peep in being fixed on luminance meter
Mirror platform, measures the brightness value of 5 points.The computing formula specified according to standard, effective luminosity rate of calculating optical sight glass.
If measuring non-visual endoscope, then integrating sphere opening adapter can be removed, increasing aperture area as by light source, photograph
Penetrate whole diffusing screen, whole screen is shot.
6, the measurement of relative distortion
The method that the test of relative distortion uses standard recommendation, is fixed on drafting board platform by the diffusing screen with 5 black round dots；
Endoscope is fixed on endoscope's platform, and endoscope is followed by the video imaging system that client has by oneself, and supporting mechanism is in systems.
Use distortion measurement plate, be used behind by light source.Regulation frame for movement makes distortion drafting board be positioned at field of view center, uses measurement aobvious
Micro mirror measures radial direction and the vertical dimension of each circle speckle respectively, calculates corresponding amount of distortion.
7, Light energy transfer efficiency (effective luminosity rate)
Measurement process is: uses the backlight screen of band cross groove, the brightness of regulation backlight, makes groove gradually not see Chu；Make
Luminous flux is measured with light flux meter；Take off endoscope, use luminance meter to measure this brightness value.Use micrometer telescope, regulation
And measure the ultimate range as visual field, calculate the maximum emergent pupil angle of visual field according to formula simultaneously and carry out according to the formula of effective luminosity rate
Calculate.
