Embodiment approach 1
[0107] In this embodiment, the biosensor 100 includes an angle sensitive filter 108 . Figure 7A The arrangement of analytes 122a on biosensor 100 is shown. Figure 7B show Figure 7A Sectional view along line A-A'. In this example, it is assumed that light emitted by an analyte reaches a pixel one pixel away from the pixel below the light. In other words, the closest eight pixels surrounding the pixel under this light. For example, if Figure 7A As shown, pixel 1041 is under the light emitted by analyte 122al, and pixels 1042-1049 are pixels that are only one pixel away from pixel 1041. Light emitted by analyte 122a1 may reach pixels 1041-1049.
[0108] Analyte 122a is placed on biosensor 100 . The area of one analyte 122a is equal to or smaller than the area of one pixel 104 .
[0109] In the case of fluorescence, excitation light 124 illuminates analyte 122a. The excitation light 124 can be moved from one side of the biosensor 100 to the opposite side so that th...
Embodiment approach 2
[0166] In this embodiment, the biosensor 200 includes an angle sensitive filter 108 and a first color filter 120a. Figure 9A The arrangement of analytes 122a on biosensor 200 is shown. Figure 9B show Figure 9A Sectional view along line A-A'. In this example, it is assumed that light emitted by an analyte reaches a pixel one pixel away from the pixel below the light. In other words, the closest eight pixels surrounding the pixel under this light. For example, if Figure 9A As shown, pixel 1041 is under the light emitted by analyte 122al, and pixels 1042-1049 are pixels that are only one pixel away from pixel 1041. Light emitted by analyte 122a1 may reach pixels 1041-1049.
[0167] Such as Figure 9A As shown, in the direction X, the first color filter 120a is separated by two pixels covered by the angle-sensitive filter 108, and in the direction Y perpendicular to the direction X, the first color filter 120a is separated by the angle The pixels covered by the sensitiv...
Embodiment approach 3
[0197] In this embodiment, the biosensor 300 includes an angle-sensitive filter 108, a first color filter 120a, and a second color filter 120b. Figure 11A The arrangement of analytes 122a on biosensor 300 is shown. Figure 11B show Figure 11A Sectional view along line A-A'. Figure 11C show Figure 11A Sectional view along line B-B'. Figure 11D show Figure 11A Sectional view along line C-C'. In this example, it is assumed that light emitted by an analyte reaches a pixel one pixel away from the pixel below the light. In other words, the closest eight pixels surrounding the pixel under this light. For example, if Figure 11A As shown, pixel 1041 is under the light emitted by analyte 122al, and pixels 1042-1049 are pixels that are only one pixel away from pixel 1041. Light emitted by analyte 122a1 may reach pixels 1041-1049.
[0198] Such as Figure 11A As shown, in the order of the first color filter / angle-sensitive filter / second color filter / angle-sensitive filter...
