6skew.In some embodiments, described rotating mechanism 854 is configured to be moved between described test position and image space by described mirror 642 in less than 500 milliseconds.In a particular embodiment, described rotating mechanism 854 is configured to being less than 250 milliseconds or be less than in 160 milliseconds and moved between described test position and image space by described mirror 642.
Figure 53 is the schematic diagram of the described mirror 642 at described image space.As shown in the figure, to be reflected by described mirror 642 from the described light signal 863 of described sample area 608 (Figure 38) and be directed toward the described detector surface 844 of described imaging detector 610.According to the configuration of described optical system 842 and the z-position of described sample holder 610, described sample area 608 can fully in focus or not fully in focus (i.e. out of focus).Figure 53 illustrates two plane of delineation 848A and 848B.Described plane of delineation 848A is overlapping with described detector surface 844 substantially, and on this point, corresponding sample image has acceptable or enough focal powers.But described plane of delineation 848B and described detector surface 844 are spaced apart.Therefore, the sample image obtained when described plane of delineation 848B and described detector surface 844 are spaced apart may not have enough focal powers.
Figure 54 and Figure 55 illustrates sample image 870 and 872 respectively.When described plane of delineation 848A is overlapping with described detector surface 844, described sample image 870 is images that described imaging detector 610 detects.When described plane of delineation 848B is not overlapping with described detector surface 844, described sample image 872 is images that described imaging detector 610 detects.(described sample image 870 and 872 comprises the DNA bunch providing fluorescent emission when scheduled excitation spectrum excites.) as shown in Figure 54 and 55, described sample image 870 has acceptable focal power, wherein be clearly defined along described in described sample image 870 bunch each, and described sample image 872 does not have each acceptable focal power be clearly defined of wherein said bunch.
Figure 56 is the schematic diagram of the described mirror 642 at described focal position.As shown in the figure, at the described mirror 642 of described focal position by around described axle R
6rotate θ angle.Equally, to be reflected by described mirror 642 from the described light signal 863 of described sample area 608 (Figure 38) and be directed toward the described detector surface 844 of described imaging detector 610.But the described optical system 842 in Figure 56 is provided so that the described plane of delineation 848 is moved by relative to described detector surface 844.More specifically, the described plane of delineation 848 can't parallel and described detector surface 844 extend, and on the contrary, intersects at crossing on the same level point PI with described detector surface 844.Although described mirror 642 is in described focal position, described imaging system 600 can obtain the test pattern of described sample area 608.As shown by the circuit diagram of figure 56, the focal degree of described sample area 608 during depending on imaging session, described crossing on the same level point PI can betide the diverse location in described detector surface 844.
Such as, Figure 57 and Figure 58 illustrates test pattern 874 and 876 respectively.Described test pattern 874 represents the image obtained when described sample area 608 is in focus, and described test pattern 876 represents the image obtained when described optical system 842 out of focus.As shown in the figure, described test pattern 874 has focal zone or position FL
1(distance of itself and described reference edge 880 is XD
1) and described test pattern 876 there is focal zone or position FL
2(distance of itself and described reference edge 880 is XD
2).Described focal position FL
1and FL
2can be determined by image analysis module 656 (Figure 38).
Confirm the described focal position FL in described test pattern 874 and 876
1and FL
2, described image analysis module 656 can determine the position of best focal power in corresponding test pattern.More specifically, described analysis module 656 can determine the focusing score of the difference of the x-dimension along described test pattern 874 and 876.Described analysis module 656 can calculate the focusing score on each point based on one or more image quality parameter.The example of image quality parameter comprises the square error in picture contrast, spot size, signal noise ratio (snr) of image and described image between pixel.For example, when calculating focusing score, described analysis module 656 can calculate the variation factor of contrast in described image.The variation factor of described contrast represents the variable quantity in the selected part of image or image between image pixel intensities.As a further example, when calculating focusing score, described analysis module 656 can calculate the size of the hot spot deriving from described image.Described hot spot can be expressed as Gauss's hot spot and size can be measured as full width at half maximum (FWHM), and in this case, less spot size is usually relevant to the focusing improved.
After determining focal position FL described in described test pattern, described analysis module 656 then can measure or determine described focal position FL and described reference edge 880 is spaced apart or the described distance XD that separates.Described distance XD then can be relevant relative to the z-position of described sample plane 846 to described sample area 608.Such as, described analysis module 656 can determine the described distance XD shown in Figure 58
2correspond to the described sample area 608 with described sample plane 846 distance, delta z.On this point, then described sample holder 650 can be moved described distance, delta z, with described sample area 608 mobile in described sample plane 846.Therefore, the described focal position FL in test pattern can indicate described sample area 608 relative to the position of described sample plane 846.As used herein, phrase " indicates described object (or sample) relative to the position of described object (or sample) plane " and comprises and utilizes factor (such as described focal position), to provide more suitably for determining model or the algorithm of described distance, delta z.
