Abstract
The utility model relates to an optical experimental image measuring and processing device. In the utility model, the position of a viewing screen of an optical instrument is provided with a CCD light intensity sensor, and the utility model is otherwise provided with an image card being matched with a PC. The CCD is used for collecting interference patterns which are inputted in a microcomputer for changing analog signals of optical images into digital signals, and the radius of circular rings can be quantitatively computed by a self compiled software and light distribution curves are displayed on a computer. The utility model improves experiment conditions and experiment accuracy and can automatically observe, measure and process optical interference images and other light source experiment images.
Description
The utility model relates to a kind of measurement treating apparatus of Experiments of Optics image, relates in particular to the measurement treating apparatus of light source experiment images such as observation, measurement, processing interference of light.
Experiments of Optics at present can not be gathered the spatial positional information of optical image purely with eye-observation, and record and computational data are harder in half dark half bright laboratory, and student experimenting is more dull.
The purpose of this utility model is: the measurement treating apparatus that a kind of light sources such as observation, measurement, processing interference of light experiment image of measurement treating apparatus, especially robotization of Experiments of Optics image is provided.
The purpose of this utility model is achieved in that a kind of measurement treating apparatus of Experiments of Optics image, it is characterized in that being provided with the CCD light intensity sensor at the film viewing screen place of optical instrument, and other is provided with the image card that cooperates with PC.CCD gathers interference pattern, by image card input microcomputer the simulating signal of optical image is become digital signal, goes out annular radii and demonstrates the curve of light distribution with self-editing software quantitative Analysis on computers.
Characteristics of the present utility model are: the measurement treating apparatus of Experiments of Optics images is provided, has improved experiment condition and experimental precision, light source experiment images such as the observation of energy robotization, measurement, processing interference of light.
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is the utility model structural representation
In embodiment and Tu, can Michelson interferometer in the frame of broken lines, gather interference pattern at original film viewing screen place with the CCD light intensity sensor, sensor is the MTV-1881Ex type.By image card, image card is the VIDEO-PCI-XR type, by its input microcomputer the simulating signal of optical image is become digital signal, promptly can show and measure on computers.If go out annular radii and demonstrate the curve of light distribution just more perfect with self-editing simple software quantitative Analysis.The spacing of checking equal inclination interference annulus that on computers can be successful and the inverse relation of radius of circle etc., this is that visual method can't be accomplished.When experiment, catch the imaging center of circle earlier, by the gray scale coordinate data of upper and lower, left three directions of image card collection,, thereby be calculated to be picture diameter etc. by three direction calculating limits.
The success of the measurement treating apparatus of this enforcement, to using CCD and microcomputer collection, measuring and handle other optical images (as Newton ring etc.) and promote the optical measurement modernization that realistic meaning is arranged, caused the very big interest of student simultaneously, promoted the further raising of physics experiment teaching quality this type of experiment.
