Reflectance coating 132, last reflectance coating 132 reflection amplification and the equivalent display image 1101 ' positioned at a distant place are to being sitting in driving for automobile 2
The eyes of the user 3 of seat 24 are sailed, therefore user 3 toward the viewing of the direction of windshield 22 it can be seen that caused by spherical mirror 10 just
Vertical amplification and equivalent remotely located display image 1101 '.Reflectance coating 132 wherein on windshield 22 can be by a dark-coloured film
Or other optical coatings substitute, to allow amplification and equivalent remotely located display image 1101' caused by optical imaging device 1
It is projected on reflectance coating 132, dark-coloured film or optical coating, allows user 3 to can pass through reflectance coating 132, dark-coloured film or optical coating
Clearly watch amplification and equivalent remotely located display image 1101' caused by optical imaging device 1.
The effect of optical imaging device 1 of the optical imaging device 1 of right the present embodiment except can reach above-described embodiment, separately
It is that the optical imaging device 1 of the present embodiment can stop automobile with the effect of difference of the optical imaging device 1 of above-described embodiment
The sunshine of 2 outside produces luminous point through windshield 22 and spherical mirror 10 around display module 11, and influences display
The display quality of image 1101, because automobile 2 outside sunshine from windshield 22 penetrate to polariscope 12 when, sunshine is first
The light polarizing film 132 of windshield 22 is disposed through, light polarizing film 132 changes sunshine and polarized toward single polarization direction, right polarisation
The polarizing axis of mirror 12 and the polarizing axis of light polarizing film 132 are mutually perpendicular to, therefore the sunshine through light polarizing film 132 can not pass through polariscope
12, therefore sunshine can not be transferred to display module 11 through spherical mirror 10, that is, reach the effect of above-mentioned, wherein automobile 2 is outer
The sunshine in portion refers to several subparallel sun of bang path for being transmitted with spherical mirror 10 and showing image 1101 ' to windshield 22
Light.In addition to above-mentioned, the optical imaging device 1 of the present embodiment is installed together in the manufacturing process of automobile 2, certain following embodiments
Also illustrate that optical imaging device 1 can be installed after automobile 2 completes manufacture.
Referring to Fig. 8, its schematic diagram for the optical imaging device of the fifth embodiment of the present invention；As illustrated, this reality
Apply the spherical mirror 10 of the optical imaging device 1 of example and polariscope 12 is arranged at a housing 15, housing 15 has an opening 151 and one
Accommodation space 152, spherical mirror 10 are arranged in accommodation space 152, are the spherical mirror 10 of concave surface towards opening 151, polariscope 12
The opening 151 of housing 15 is arranged at, and positioned at the top of spherical mirror 10.The housing 15 of spherical mirror 10 and polariscope 12 will so be loaded
The surface for the car body 23 being arranged between the instrument panel seat 21 of automobile 2 and windshield 22, spherical mirror 10 is set to be located at display module
Caused by 11 on the bang path of display image, simultaneously towards windshield 22, to transmit through caused by spherical mirror 10
Amplify and the equivalent display image positioned at a distant place is to windshield 22.
So the optical film 13 of the present embodiment is with the difference of optical film 13 of above-described embodiment, the optical film 13 of the present embodiment
Non-plated is on whole windshield 22, but plating is set or is attached on local windshield 22, the polarisation of right optical film 13
Film 131 directly contacts windshield 22, and reflectance coating 132 is arranged at light polarizing film 131, and optical film 13 is located at caused by spherical mirror 10
Display image is transferred on the path of windshield 22 through polariscope 12.The optical imaging device 1 of the present embodiment can reach with
The effect of as the optical imaging device 1 of above-described embodiment, and the optical imaging device 1 of the present embodiment can be according to the need of user
Ask and installed.
