(4) Tu Xiang amplification and demonstration
Light beam, amplifies through magnifier after catoptron repeatedly reflects by the thing sheet again, presents the image of amplification at last on the imaging screen.
(5) shell
Because this device needs bigger imaging screen, long fuselage for reducing the volume of instrument, makes the imaging screen foldable in side panel.
Compared with the prior art the present invention has following advantage:
(1) N thing sheet can once be contained in the edge groove on dish top, garden, mixing up the position just no longer needs to dismantle repeatedly and regulated later on, with which thing sheet demonstration optical phenomena, just presses and this thing sheet corresponding buttons, driven by motor garden dish rotates, and this thing sheet just in time is parked in the middle of the light beam.Thereby this device using and managing very conveniently, saved the time greatly, enriched the content of demonstration.
(2) because light beam repeatedly reflects through catoptron, amplify through magnifier, the image that presents on the imaging screen is amplified to quite clearly degree at last again, thereby makes the Most students in the classroom that can hold 270 people can see experimental phenomena clearly.
Accompanying drawing 1 is the structural drawing of automated optical apparatus for demonstrating, (1) large reflective mirror wherein, (2) auxiliary reclay, (3) web member, (4) backstay, (5) driving lever, (6) small reflector, (7) pilot pin, (8) garden dish, (9) hilted broadsword N throws waver, (10) thing sheet, (11) motor, (12) belt pulley, (13) thumb wheel, (14) pillar, (15) mirror disk, (16) catoptron in the light source, (17), (18) imaging screen.
One embodiment of the present of invention: can N thing sheet (10) be arranged around dish (8) upper edge place, garden that Z-axis rotates at one, the light beam that sends from light source (16) is penetrated on some N thing sheet, interference diffraction light through the thing sheet is mapped on the small reflector (6), be reflected to again on the middle catoptron (17), be mapped on the large reflective mirror (1) from the light of (17) reflection, the light that reflects from (1) reflects the length that (drawing the figure) has been equivalent to increase instrument through several times again.Also have a magnifier in light path, its effect makes the interference diffraction pattern amplify.The lower axial end of garden dish (8) connects a hilted broadsword N and throws waver, and the garden dish rotates around Z-axis under slow speed motor drives.Garden web upper side has N pilot hole evenly to distribute, and near dish side, garden one taper pilot pin (7) is being arranged, and pilot pin is coiled in the pilot hole of side in the insertion garden immediately after the garden dish stops operating.Pilot pin is contained in one can be around an end of the backstay (4) of a rotation, and the other end of backstay is subjected to the control of auxiliary reclay (2).The contact of auxiliary reclay is connected in the motor circuit, the rotation of control motor and garden dish.The wire loop series connection hilted broadsword N of auxiliary reclay throws waver (9), and hilted broadsword N throws N contact of waver and connects with N button respectively.This N button generally is in on-state, uses which button just it to be placed off state.When hilted broadsword N threw waver and only forwards the corresponding position of button with this off state to, the auxiliary reclay wire loop just cut off the power supply, and motor and garden dish stop operating, and a thing sheet in N thing sheet stops in the middle of the light beam.Can select N any one that demonstrate in the image by N button like this.Above say so dials auto-man switch (24) to manual position.Auto-man switch is dialled to automated location, and then N the contact and N the coupled button of hilted broadsword N throwing waver are divided into odd number and even numbers two groups of (20), (21).The normal open contact of the other end of each odd number button and little relay connects together, and the other end of each even numbers button and the normally open contact of little relay connect together.Having an oscillatory circuit (23) to send normal open, the normally open contact that a signal makes little relay second every t alternately connects with auxiliary reclay (2) coil.Make each thing sheet in light path, stop t second, forward next thing sheet again to.
