[embodiment]
See also Fig. 2 to Fig. 9, optical input apparatus of the present invention such as optical mouse, it comprises housing 4, optical sensor module 1, infrared light emission source 2 and reflective lens module 3, and this optical sensor module 1, infrared light emission source 2 and reflective lens module 3 all place this housing 4 inside.This optical sensor module 1 and infrared light emission source 2 are installed in the top that also this circuit board is placed reflective lens module 3 on the circuit board, this light emitting source 2 as existing infrared LEDs.This reflective lens module 3 comprises pedestal 31, prism 32, spectroscope 33 and lens 34, and wherein prism 32 is embedded on the pedestal 31 corresponding installation position 317 and is located at a side of light emitting source 2 emergent lights; Spectroscope 33 is embedded into installation position 314 corresponding on the pedestal and is located at a side of prism 32 emergent lights; Lens 34 are embedded into installation position 315 corresponding on the pedestal and are located at a side of spectroscope 33 emergent lights, thereby four combination of components are integral and become this reflective lens module 3 thus, and this module also can be integrated injection molding certainly.In the present embodiment, this prism 32 is positioned at a side of light emitting source 2 emergent lights, and this spectroscope 33 is positioned at a side of these prism 32 emergent lights, and lens position 34 is in a side of these spectroscope 33 emergent lights, and optical sensor module 1 then is positioned at a side of these lens 34 emergent lights; Described lens 34 special single focus or bifocus or the multifocal high precision aspheric curves of adopting, so that optical sensor module 1 assembly can absorb more dielectric surface optical image information, absorb the more ability of the image information of multimedium body surface such as high glossy surface (glass/marble surface/metal surface/clear plastic surface/photo paper surface) and variegated surface thereby improve this reflective lens module.The machinery of this optical input apparatus and circuit structure do not repeat them here as described in the prior art.
The principle of work of this optical input apparatus is as follows: 32 refractions produce a light beam L1 parallel with dielectric surface S to the light beam that is sent by light emitting source 2 through prism, this light beam L1 is transmitted to the plane of refraction of spectroscope 33, the included angle A that is produced with respect to dielectric surface S by spectroscope 33 refraction backs is the light beam L1 of 90.00 degree, the projecting beam optical axis of these 90.00 degree is refracted to the more transmission plane S of multimedium object such as high glossy surface (glass/marble surface/metal surface/clear plastic surface/photo paper surface) and variegated surface, and once or reflex to spectroscope 33 once with the image on transmission plane (the being dielectric surface) S, through spectroscope 33 image strip L2 is reflexed to lens 34 again, thereby make the optical sensor module 1 in optical profile type (wired and wireless) Genius mouse or other optical input apparatus absorb the image of handling through lens 34.
By the processing of this reflective lens module, can realize allowing the sensor module of optical profile type (wired and wireless) Genius mouse and other optical input apparatus can absorb the more lip-deep image of multimedium such as high glossy surface (glass/marble surface/metal surface/clear plastic surface/photo paper surface) and variegated surface.
The method of a kind of optics input of the present invention comprises the steps: 1) luminous by the infrared light emission source; 2) produce a light beam parallel after the anaclasis of this infrared light sources being sent by prism, and this light beam is projected spectroscopical plane of refraction with dielectric surface; 3) will project the angle that produces with respect to dielectric surface behind the refraction of optical beam on the spectroscope projection surface by spectroscope is the light beams of 90 degree; 4) with this and dielectric surface angle be the transmission plane that the projecting beam optical axises of 90 degree are refracted to the medium object, and with the image on the transmission plane once or reflex to spectroscope once; 5) by spectroscope image strip is reflexed to lens, thereby make optical sensor module absorb the image of handling through lens.
Among the present invention, because of the angle of spectroscope 33 is 45 degree (promptly the angle between this spectroscope and the dielectric surface is 45 degree), in order to make the light beam that produces behind this light beam L1 process spectroscope 33 for vertically being transmitted to dielectric surface S, this projects spectroscopical light beam and is necessary for level and injects according to the light refraction principle, so must guarantee through the light beam after prism 32 refractions parallel with media plane S.
Among the present invention, parallel in order to guarantee to make light beam with media plane S through after prism 32 refractions, adopted the prism of 45 degree, follow principle according to light refraction, incident light penetrates for level through the prism 32 reflection backs of 45 degree, in order to guarantee that outgoing luminous energy projects dielectric surface S accurately, must guarantee the optical axis coincidence of outgoing beam, spectroscope 33 and lens 34.
Vertical with dielectric surface S in order to guarantee to make the light beam through after spectroscope 33 refractions, spectroscope 33 is adopted as the angle of 45 degree.Following the principle according to light refraction, is vertical the photograph to dielectric surface S after spectroscope 33 refractions through 45 degree.In order to guarantee to project the optical axis of spectroscope 33 and lens 34 accurately and make it to overlap through prism 32 outgoing beams, require spectroscopical position to overlap with lens 34 centers in vertical direction, require ejaculation optical axis coincidence in the horizontal direction with prism.
Among the present invention, for the light path that realizes vertical illumination and lens picked-up image at same optical axis and make it overlapping, adopt by spectroscope 33 and reflect back generation 90 degree normal beams according to absorbing image to dielectric surface S, again once or reflex to spectroscope 33 once by the image on transmission plane (the being dielectric surface) S, through spectroscope 33 image strip L2 is reflexed to lens 34 again, thereby make the optical sensor module 1 in optical profile type (wired and wireless) Genius mouse or other optical input apparatus can absorb the image of handling through lens 34 accurately.
Among the present invention, because adopt the method for vertical transmission, so can satisfy different dielectric surface characteristics, the needs different with color as reflectivity.
