In the embodiment, the filter film 110 splits the light from the incident light source to achieve the spectrum detection function of the spectrum chip, and the thickness of the filter film 110 includes but is not limited to no greater than 0.5mm, for example, the thickness of the filter film 110 may be 0.3mm, 0.4mm, 0.31mm, 0.12mm, etc., it should be understood that the filter film 110 is different from filter glass.

In one possible implementation, the filtering material may be directly printed on the substrate 120 to form the filtering film 110, in which case, the filtering film 110 may be referred to as a filtering layer, and it is not necessary to form the filtering film 110 in advance and then place the formed filtering film 110 on the substrate 120. The filter material may for example comprise quantum dots with different light absorption and emission characteristics.

In one possible implementation manner, instead of forming the filtering film 110 on the substrate 120 by printing, the filtering film 110 may be formed first and then the formed filtering film 110 is disposed on the substrate 120.

The chip target surface 130 receives and outputs a detection signal, which is a signal of the intensity of the light transmitted from the optical filter film 110; the substrate 120 serves to protect the filter film 110 from damage and contamination, and it should be understood that the substrate 120 may also filter out optical signals that interfere with detection.

In one implementation, the substrate 120 may be formed of a material including, but not limited to, quartz glass or a highly light transmissive plastic such as PET, PC, PS, etc., a light filtering material, and the like. Among them, different usage scenarios have different requirements on the optical performance of the material of the substrate 120, and generally require that the transmittance of the substrate 120 in the usage wavelength range is greater than 90%.

In one implementation, the filter film 110 may include:

the first region is provided with quantum dots and is positioned at a first position of the light filtering film, which corresponds to a first substrate position of the substrate; and

a second region located at a second position of the filter film corresponding to a second substrate position of the substrate, wherein the first position is different from the second position.

In one implementation, the second region is not populated with quantum dots.

In this embodiment, the filter film 110 may be divided into a first region and a second region, the quantum dots may be disposed in the first region, and the second region may be a transparent region where the quantum dots are not disposed, and the incident light from the light source irradiates the first region and the second region. It should be understood that the chip target surface 130 receives the light transmitted from the first region and outputs a first signal as the intensity of the light transmitted from the first region, and receives the light transmitted from the second region and outputs a second signal as the intensity of the light transmitted from the second region, and the detection result of the spectroscopic chip 100 is based on the first signal and the second signal.

The utility model discloses an except arranging the first region of laying the quantum dot in the first position department of filter film 110, still arrange the second region of not laying the quantum dot in the second position department of filter film 110, therefore, chip target surface 130 detectable is from the intensity of the first region light that transmits that distributes in the first position department of filter film 110 and output the first signal that corresponds with this intensity, chip target surface 130 still can detect from the intensity of the second region light that transmits that distributes in the second position department of filter film 110 and output the second signal that corresponds with this intensity, usable this second signal carries out intensity spatial distribution's correction, in order to eliminate the spectral measurement error that leads to because intensity spatial distribution.

In this case, the second region may be used to filter out stray light.

Of course, the second region may also be a light-transmitting structure capable of transmitting a predetermined amount of light, and the second region includes, for example, but not limited to, a semi-light-transmitting portion in the related art.

In this embodiment, the shape of the first region may include, but is not limited to, any one or more of the following: the shape of the first region included in the same filter film may be the same shape of the aforementioned shapes, or may be at least one of the aforementioned shapes. For example, assuming that the first regions included in the same optical filter film are divided into a first group and a second group, the shapes of all the first regions belonging to the first group are a first shape and the shapes of all the first regions belonging to the second group are a second shape, the first shape may be the same as the second shape, and of course, the first shape may be different from the second shape.

Similarly, the shape of the second region may also include, but is not limited to, any one or more of the following: the shape of the second region included in the same filter film may be the same shape of the aforementioned shapes, or may be at least one of the aforementioned shapes. For example, assuming that the second regions included in the same filter film are divided into a third group and a fourth group, the shapes of all the second regions belonging to the third group are the third shape and the shapes of all the second regions belonging to the fourth group are the fourth shape, the third shape may be the same as the fourth shape, and of course, the third shape may be different from the fourth shape.

In addition, it should be understood that the first region and the second region included in the same filter film may have the same or different shapes. For example, at least one of the first shape and the second shape may be the same as at least one of the third shape and the fourth shape, or both the first shape and the second shape may be different from both the third shape and the fourth shape, respectively.

In this embodiment, the sizes of the first regions included in the same filter film may be equal or different, and correspondingly, the sizes of the second regions may be equal or different, and the sizes of the first regions and the second regions included in the same filter film may be equal or different. The description about the dimensions is similar to that about the shapes and will not be repeated here.

Because the filtering film of spectrum chip is including laying the first region of quantum dot and not laying the second region of quantum dot, consequently, the utility model discloses a spectrum chip can come to rectify the signal of the intensity of the light that the first region transmits out based on the signal of the intensity of the light that transmits out from the second region to can effectively eliminate because the spectral detection error that intensity spatial distribution leads to, can improve spectral resolution from this.

In one possible implementation, the layout of the first and second regions is determined according to information related to the correction of the spatial distribution of the intensity of the incident light source and/or the dimensions of the chip target surface and the filter film.

In this embodiment, the layout of the first region and the second region may be determined (or selected) based on information related to the correction of the spatial distribution of intensity, such as the correction accuracy and/or the size of the target surface of the chip and the filter film.

In one possible implementation, the first regions and the second regions are laid out in a layout manner in which a first number of second regions of corresponding size and shape are arranged in first corresponding positions and a second number of first regions of corresponding size and shape are arranged in second corresponding positions, so that the correction accuracy of the spectral chip thus fabricated satisfies a correction threshold under the condition that the sizes of the chip target surface and the filter film are satisfied.

In the present embodiment, the number, shape, size, and position of the second regions are determined in accordance with the correction accuracy and the sizes of the chip target surface and the filter film, and the second regions are laid out in such a manner that the determined number of second regions having the determined size and shape are disposed at the determined positions, and accordingly, the number, shape, size, and position of the first regions are determined in accordance with the correction accuracy and the sizes of the chip target surface and the filter film, and the determined number of first regions having the determined size and shape are disposed at the determined positions. A specific example can be seen in fig. 2g, wherein the dashed blank block in fig. 2g represents the second area and the shaded block represents the first area.

Therefore, the number, the shape, the size and the position of the first area and the second area can be selected at will according to actual needs, and the number, the shape, the size and the position of the first area and the second area are not limited, so that the customized spectrum chip can be realized.

In a possible implementation, in the presence of a light spot, a greater number and/or a greater size of second regions are provided at the edge of the light spot than inside the light spot; and/or providing a greater number and/or size of second regions at locations where the spots overlap than at locations where the spots do not overlap.

In this embodiment, the layout manner of the second region may be determined according to the condition of the light spots, for example, the layout manner of the second region corresponding to each light spot is determined for each light spot; in the case where a plurality of light spots exist, some more second regions are provided at the edges of the respective light spots, some more second regions are provided at positions where the light spots overlap, and the second regions are reduced in the other regions. Specific example referring to fig. 2h, as shown in fig. 2h, there are two spots of spot 1 and spot 2, and there are overlapping areas of spot 1 and spot 2, the second area is provided as much as possible in the overlapping area, and the second area is provided as much as possible at the edge of the non-overlapping area of spot 1 and spot 2.

Therefore, the area of the chip target can be utilized to the maximum extent, and the utilization rate of the spectrum chip can be improved; in addition, the design can be targeted according to different light spot conditions.

In one possible implementation, in a case where the intensity spatial distribution of the incident light source is uniform, if the entire filter film includes a plurality of rectangular blocks, the first region and the second region are laid out in a layout manner in which the rectangular blocks at the respective positions are set as the second region, the rectangular blocks at the remaining positions are set as the first region, and the set second regions are uniformly distributed in the plurality of rectangular blocks.

It should be understood that uniform distribution means that the spatial distribution of the irradiance across the target surface of the wafer has a relative standard deviation of no greater than 5%, in one implementation, uniform distribution means that the spatial distribution of the irradiance across the target surface of the wafer has a relative standard deviation of no greater than 3%, and in another implementation, uniform distribution means that the spatial distribution of the irradiance across the target surface of the wafer has a relative standard deviation of no greater than 1%.

In this embodiment, under the condition that the intensity of the incident light source is uniformly distributed in space, the whole filter film is assumed to include M × N rectangular blocks, and the position of each rectangular block is a_i,jWherein i denotes a row number and j denotes a column number, i ═ 1,2, … MAnd j is 1,2, … N, where M and N are positive integers, the rectangular tiles at the corresponding positions may be set as the second region and the rectangular tiles at the remaining positions may be set as the first region, and the set second regions are uniformly distributed among the M × N rectangular tiles.

In one possible implementation, M equals 5 and N equals 7. As shown in fig. 2a, the black rectangular area corresponds to the first area, the blank rectangular area corresponds to the second area, the filter film is divided into 35 rectangular areas of 5 × 7, and the positions of the 35 rectangular areas are a_i,jWherein i is 1,2, … 5, j is 1,2, … 7, position a_1,1、A_1,4、A_1,7、A_2,2、A_2,6、A_3,1、A_3,4、A_3,7、A_4,2、A_4,6、A_5,1、A_5,4And A_5,7The rectangular blocks are set as the second area, and the rest position is A_1,2、A_1,3、A_1,5、A_1,6、A_2,1、A_2,3、A_2,4、A_2,5、A_2,7、A_3,2、A_3,3、A_3,5、A_3,6、A_4,1、A_4,3、A_4,4、A_4,5、A_4,7、A_5,2、A_5,3、A_5,5And A_5,6The rectangular blocks are respectively set as the first areas.

For the layout mode shown in fig. 2a, the whole filtering film is divided into a plurality of adjacent rectangular blocks, a rectangular block set uniformly distributed on the whole filtering film in a certain proportion (number) is selected, each rectangular block in the set is respectively set as a second area, and each rectangular block outside the set is respectively set as a first area.

As shown in fig. 2b, the black rectangular area corresponds to the first area, the blank rectangular area corresponds to the second area, the filter film is divided into 49 rectangular areas of 7 × 7, and the corresponding positions of the 49 rectangular areas are a_i,jWherein i is 1,2, … 7, j is 1,2, … 7, position a_2,2、A_2,3、A_2,5、A_2,6、A_3,2、A_3,3、A_3,5、A_3,6、A_5,2、A_5,3、A_5,5、A_5,6、A_6,2、A_6,3、A_6,5And A_6,6The rectangular blocks are set as the first area and the rest position is A_1,1、A_1,2、A_1,3、A_1,4、A_1,5、A_1,6、A_1,7、A_2,1、A_2,4、A_2,7、A_3,1、A_3,4、A_3,7、A_4,1、A_4,2、A_4,3、A_4,4、A_4,5、A_4,6、A_4,7、A_5,1、A_5,4、A_5,7、A_6,1、A_6,4、A_6,7、A_7,1、A_7,2、A_7,3、A_7,4、A_7,5、A_7,6And A_7,7The rectangular blocks are respectively set as second areas.

For the layout shown in fig. 2b, the whole filter film is divided into "tian" grids, four rectangular blocks in the "tian" grids are set as the first areas, and each rectangular block on the "tian" word line is set as the second area.

Compared with the layout shown in fig. 2a, the layout shown in fig. 2b has a higher blank ratio, i.e., the ratio of the second region in the whole filter film is higher, and accordingly, the utilization rate of the target surface of the chip is lower.

In one possible implementation, in a case where the spatial distribution of the intensity of the incident light source is not uniform, if the entire filter film includes a plurality of rectangular blocks, the first region and the second region are laid out in a layout manner in which the rectangular blocks are set as the first region and the second region is set in the gap between the rectangular blocks.

In the present embodiment, in the case where the intensity spatial distribution of the incident light source is not uniform, assuming that the entire filter film includes a plurality of rectangular blocks, the rectangular blocks may be set as the first regions and the second regions may be set in the gaps between the rectangular blocks.

In one possible implementation, M equals 5 and N equals 7. As shown in fig. 2c, the black rectangular block corresponds to a first area, the blank rectangular block corresponds to a second area, the filter film is divided into 35 rectangular blocks of 5 × 7, each of the 35 rectangular blocks is set as the first area, and one second area is respectively set at four side positions of a circumscribed rectangle spaced apart from the respective rectangular blocks by a corresponding distance. For the layout shown in fig. 2c, sufficient space is reserved between the first regions.

In one possible implementation, M equals 5 and N equals 7. As shown in fig. 2d, the black circular block corresponds to a first area, the blank rectangular block corresponds to a second area, the filter film is divided into 35 circular blocks of 5 × 7, each of the 35 circular blocks is set as the first area, and one second area is respectively set at four corner positions of a circumscribed rectangle spaced apart from each circular block by a corresponding distance. For the layout shown in fig. 2d, enough space is reserved at the four corners of the first area.

In one possible implementation, M equals 5 and N equals 7. As shown in fig. 2e, the black rectangular block corresponds to a first area, the blank rectangular block corresponds to a second area, the filter film is divided into 35 rectangular blocks of 5 × 7, each of the 35 rectangular blocks is set as the first area, and one second area is respectively set at four side positions and four corner positions of a circumscribed rectangle spaced apart from each rectangular block by a corresponding distance. For the layout shown in fig. 2e, enough gaps are reserved between the four corners of the first area and the first area.

In the present embodiment, in the case where the required spectral resolution is lower than the threshold, assuming that the entire filter film is divided into a plurality of bands, the band at the corresponding position may be set as the first region and at least one second region may be set at the corresponding position of four sides of a circumscribed rectangle spaced apart from the band by a corresponding distance.

In one possible implementation, M equals 2 and N equals 9. As shown in fig. 2f, the black stripe corresponds to a first area, the blank rectangular block corresponds to a second area, the filter film is divided into 18 stripes of 2 × 9, each of the 18 stripes is set as the first area, and two second areas are respectively provided at symmetrical positions of two long sides of a circumscribed rectangle spaced apart from the respective stripes by a corresponding distance, and one second area is provided at a position of at least one short side of the circumscribed rectangle. For the layout shown in fig. 2f, the first regions and the second regions are arranged alternately.

In the present embodiment, in the case where the required spectral resolution is lower than the threshold value, the stripe-shaped first regions are used, and the stripe-shaped first regions may be arranged in accordance with a predetermined rule at corresponding positions of the filter film, while the second regions may be arranged at remaining positions of the filter film.

In one possible implementation, it is considered that making small blocks of filter film uniform at the pixel level is very difficult in process and time consuming. Thus, in some application scenarios where too high a spectral resolution is not required, e.g. application scenarios where the spectral resolution is below a threshold value, a strip-type first region with easier processing may be used. For the stripe-type first region, a layout manner such as shown in fig. 2f and 2r may be adopted. Of course, the stripe-shaped first region may be used only for a part of the first region on the same filter film, for example, the layout shown in fig. 2 m.

In a possible implementation manner, considering that the same object has different imaging under quantum dot stripes with different wavelengths, which may affect image stitching using different quantum dot stripes, one quantum dot stripe cannot sweep over two side surfaces (two sides along the sweeping direction) of the three-dimensional object through one sweeping, so that for the three-dimensional object, a situation of spectrum information loss may occur. Therefore, the utility model discloses use the second region and solve the problem that three-dimensional object spectrum lacked through the strip arrangement mode of difference.

By the second region, it makes the stitching algorithm more robust; the problem that the spectral information of the three-dimensional object is not complete due to deficiency can be solved by using the same quantum dot strips on the two sides of the target surface of the chip.

It should be understood that the second region and the first region can be combined at will, and the present invention can also adopt other layout ways, limited by space, and the present invention is not expanded in detail.
