Kinematic imaging system
Disclosed herein, inter alia, are imaging systems, devices, and methods of use thereof.
1. An imaging system, comprising:
a base platform;
a camera mounted on the base platform;
at least one electromechanical component coupled to the base platform, the electromechanical component configured to adjust a position or orientation of the camera relative to a sample stage of a bioanalytical instrument to correct for tilt of an image plane of the camera relative to a sample of the sample stage;
wherein the sample stage translates in an xy plane, and the at least one electromechanical component automatically moves the camera along a polar angle formed between the z axis and the normal vector of the xy plane.
2. The imaging system of claim 1 , wherein the camera comprises a complementary metal-oxide-semiconductor (CMOS) array, a charge-coupled device (CCD) array, or a CCD-CMOS sensor array.
3. The imaging system of claim 1 , wherein the at least one electromechanical component comprises at least one motor attached to the base platform.
4. The imaging system of claim 3 , wherein the at least one motor is a stepper motor, piezo motor, brushless motor, hysteresis motor, linear motor, or a servomotor.
5. The imaging system of claim 4 , wherein the stepper motor includes an integrated ball spline.
6. The imaging system of claim 1 , wherein the at least one electromechanical component comprises at least one electrically actuated motor attached to the base platform.
7. The imaging system of claim 1 , wherein the at least one electromechanical component comprises at least one camera focus and tilt motor configured to positionally adjust the camera so that the camera can focus on imaging a region of interest.
8. The imaging system of claim 1 , wherein the imaging system defines a tip/tilt plane that is coincident with an image plane of the camera.
9. The imaging system of claim 1 , wherein the base platform is movable relative to the sample stage.
10. The imaging system of claim 1 , wherein the sample stage is capable of moving independently relative to the sample stage base platform.
11. The imaging system of claim 1 , wherein the at least one electromechanical component automatically moves the camera upward or downward to allow for adjusting the camera to an optimal focal plane.
12. The imaging system of claim 1 , wherein the at least one electromechanical component is configured to rotate the camera.
13. The imaging system of claim 1 , wherein the at least one electromechanical component rotates the camera to allow for adjusting the camera to an optimal focal plane.
14. The imaging system of claim 1 , wherein the sample stage further comprises a flow cell or a multiwell container.
15. The imaging system of claim 1 , wherein the camera further comprises one or more lenses, a beam splitter, one or more pinhole apertures, excitation filter, or combinations thereof.
16. The imaging system of claim 15 , wherein the at least one mechanical component moves the one or more lenses upward or downward to allow for adjusting the camera to an optimal focal plane.
17. The imaging system of claim 1 , wherein the bioanalytical instrument further comprises a light source and an integrated fluidic system of one or more interconnected chambers, ports, and channels in fluid communication and configured for carrying out an analytical reaction or processes.
18. A method of imaging a sample, said method comprising obtaining an image of the sample using the imaging system of claim 1 .
19. The method of claim 18 , wherein the sample comprises one or more fluorescently labeled biomolecules.
