It is the angle of inclination (α values and β value) for detecting determinand 8.Detailed moving process is as follows：First, the first illuminating part 20 is sent
First coloured light to the first collimating mirror 21, the first collimating mirror 21 can make the advance of the first coloured light reach almost parallel in degree, to keep away
Exempting from the diverging of the first coloured light causes the loss of light energy.Afterwards, the first coloured light can directly be filtered by the first spectroscope 22 and first
(in Figure 5, pass through the first spectroscope 22 and the first color of the first optical filter 23 on speculum 81 above piece 23 to determinand
Just represented with solid line).Afterwards, the first coloured light can reflect back into the first optical filter 23 from speculum 81 and (in Figure 5, be reflected
The first coloured light that mirror 8 is reflected is to be represented by dotted lines).Afterwards, the first coloured light can return to the first light splitting through the first optical filter 23
Mirror 22, and the second spectroscope 25 is reflexed to again from the first spectroscope 22.Afterwards, first coloured light of another part can be via second point
Light microscopic 25 reflexes to the second condenser lens 26, and the first coloured light can be focused on the table of the second photographic department 27 by the second condenser lens 26 again
On face.In above-mentioned, since determinand 8 moves the difference that after preceding and movement the first coloured light can be caused to focus on the second photographic department 27

When angle of inclination (α values and β value).
Referring to Fig. 6, the schematic diagram of the depicted path of motion for the second coloured light of Fig. 6.This path of motion mainly detects
The height tolerance (Z values) of determinand 8.The detailed moving process of second coloured light is as follows：First, the second illuminating part 30 sends second
For coloured light to the second collimating mirror 31, the second collimating mirror 31 can make the advance of the second coloured light reach almost parallel in degree, to avoid the
Dichroscope dissipates the loss for causing light energy.Afterwards, the second coloured light can be slanted on the speculum 81 of the top of determinand 8 (
In Fig. 6, the second coloured light being slanted on speculum 81 is represented with solid line).Afterwards, the second coloured light can be reflexed to from speculum 81
Tertiary focusing lens 32 (the second coloured light in figure 6, reflected by speculum 8 is to be represented by dotted lines).Afterwards, tertiary focusing is saturating
Mirror 32 can focus on the second coloured light on the surface of the 3rd photographic department 33 again.It is before being moved due to determinand 8 and mobile in above-mentioned
Afterwards the second coloured light can be caused to focus on the diverse location of the 3rd photographic department 33.Therefore, optical detection apparatus 2 is according to the second coloured light
The position gap of focus point just can calculate the height tolerance (Z values) when determinand 8 moves up and down.
Referring to Fig. 7, the schematic diagram of the depicted path of motion for being the first coloured light and the second coloured light of Fig. 7.In optical detection
In the running of the actually detected determinand 8 of equipment 2, optical detection apparatus 2 is to be projected at the same time using the first coloured light and the second coloured light
On 81 speculums of determinand 8.Consequently, it is possible to optical detection apparatus 2 just can measure determinand 28 within the same time
Height tolerance (Z values), the amount of movement (X values and Y value) of angle of inclination (α values and β value) and left and right.Therefore, compared to known
Optical detection apparatus 1, the optical detection apparatus 2 of the present embodiment can also measure the amount of movement (optics of the left and right of voice coil motor more
Detection device 2 can measure Z values, α values, β value, X values and Y value, belong to the optical detection apparatus of 5 axis), so being set by optical detection
The voice coil motor of standby 2 detection more can ensure that the image quality of its camera model, be not easy to the generation of faulty materials.
In above-mentioned, when the second coloured light is exposed on determinand 28, although the second partial coloured light also can be from speculum
The first optical filter 23 is reflected back on 81.However, since the first optical filter 23 can filter out reflected from speculum 81
Dichroscope, so the second coloured light will not be incident upon the first photographic department 24, will not focus on the surface of the second photographic department 27.In detail
For thin, the first coloured light and the second coloured light of optical detection apparatus 2 will not interfere with each other.
In addition, referring again to Fig. 3, the optical detection apparatus 2 of the present embodiment further includes a control panel 7.Also, chain of command
Plate 7 is also disposed on inside main casing 200.So, 33 institute of the first photographic department 24, the second photographic department 27 and the 3rd photographic department
The signal of reception can be conveyed directly to control panel 7, so the signal is just located after need not being pulled out to 200 outside of main casing again
Reason.Also should be in this way, the optical detection apparatus 2 of the present embodiment can also reduce noise when High Speed Analog signal transmits.
Above-described embodiment it is merely for convenience explanation and illustrate, though arbitrarily repaiied by person of ordinary skill in the field
Change, all without departing from such as the scope to be protected in claims.
