Abstract
The invention discloses an image sensing device with a function of optical image amplification, and the device comprises a housing module and an image sensing module disposed in the housing module. The image sensing module comprises a light emitting unit, a first optical unit, a second optical unit, and an image sensing unit. The first optical unit is provided with a convex objective lens. The second optical unit comprises an optical ocular lens. A projection light beam generated by the light emitting unit is reflected by a plane to form a reflected light beam. The reflected light beam passes through the convex objective lens to form a focused light beam which is focused at a focusing point between the convex objective lens and the optical ocular lens. The focused light beam passes through the optical ocular lens to form an imaging light beam projected on the image sensing unit. Therefore, the reflected light beam sequentially passes through the convex objective lens and the optical ocular lens, thereby enabling an image in a preset region of the plane to be amplified and imaged on the image sensing unit through the cooperation of the convex objective lens and the optical ocular lens.

Mirror, wherein the projecting beam produced by the luminescence unit includes that one directly projects
Part I light beam on the reflecting optics, one are located at the reflecting optics and institute
State the Part II light beam between optical module and one be incident upon the described of the plane
Part III light beam in presumptive area, the Part I light beam is by the reflection
The reflection of eyeglass is forming the Part II being directly incident upon on the optical module
Light beam, the Part II light beam is direct to be formed by the reflection of the optical module
The Part III light beam being incident upon in the presumptive area of the plane, and institute
State the presumptive area that the Part III light beam of projecting beam passes through the plane
Reflection and form the reflected beams.
9. a kind of image sensing module with optical image enlarging function, it is characterised in that tool
The image sensing module for having optical image enlarging function includes：
One first optical unit, first optical unit has one to be arranged on the upper of a plane
The optical module and one of side is arranged on the convex surface object lens on the optical module；
One second optical unit, second optical unit includes one adjacent to first optics
The optical eyepiece of unit；And
One image sensing unit, the image sensing unit is adjacent to second optical unit；
Wherein, a projecting beam is projected in a presumptive area of the plane and by institute
The reflection of plane is stated to form a reflected beams, the reflected beams pass through described convex
Face object lens with formed one focus on positioned at the convex surface object lens and the optical eyepiece it
Between a focus point on focus on light beam, and the focus on light beam pass through the optics
Eyepiece is forming an imaging beam being incident upon on the image sensing unit；
Wherein, the reflected beams sequentially pass through the convex surface object lens and the optical eyepiece,
So that the image of the presumptive area of the plane is by the convex surface object lens and institute
The cooperation of optical eyepiece is stated, and is exaggerated and is imaged on the image sensing unit.
10. the image sensing module with optical image enlarging function according to claim 9,
Wherein described projecting beam passes through an optical navigation part to be incident upon the plane indirectly
In the presumptive area, the convex surface object lens include being integrally formed being arranged on the optics
On the upper surface of component and towards the optical eyepiece one first convex lenss or one into
Type is arranged on the lower surface of the optical module and towards the described predetermined of the plane
One second convex lenss in region.
