The radius of the ring measured by the binarized image is 6.5 pixels, which can be used as the initial value of the Gaussian fitting. (I) Binarized image of the diffraction ring in (G). (H) A typical diffraction ring indicated by the yellow box in (G). (G) Defocused image of particles in a cell. (F) Trajectories extracted by the plugin particle tracker in ImageJ. (E) The dialog screen of the the File–Save As–Image sequence tool in imageJ. (D) Focused image of particles in a cell. (B and C) The transformation matrix between the focused and defocused planes. EMCCD parameter setting, image sequence acquisition and shutter control are all performed by the IQ software or Micro-Manager. HILO imaging, which provides a deeper penetration depth compared with the TIRF imaging, is generally used to image fluorescence probes inside cells at a high signal-to-noise ratio ( Li et al., 2015 Tokunaga et al., 2008). By adjusting the incident angle of the focused laser, different excitation modes can be selected: highly inclined and laminated optical sheet (HILO) and epifluorescence ( Figure 1). All laser beams are combined by dichroic mirrors and coupled into an optical fiber, and then the output light is focused at the back focal plane of the objective. The laser intensities are controlled by the laser power supplies and attenuator. Mechanical shutters (Uniblitz LS6T2, Vincent Associates) are applied to control the on−off state of these lasers. In the excitation path, different wavelengths are used: a 405 nm laser (OBIS 405−100 mW, Coherent), a 488 nm laser (Sapphire 488−200 mW, Coherent), and a 561 nm laser (Sapphire 561−200 mW, Coherent). A lens (f = 400 mm) is inserted into the path of the beam with 70% intensity to generate diffraction rings. A beam splitter is installed to divide the emission signals into two beams with a 30:70 intensity ratio, and each beam is sent to one-half of the EMCCD ( Jiang et al., 2020 Toprak et al., 2007). In the two-focal imaging part, we use the dual channel simultaneous-imaging system (DV2, Photometrics) in the emission path. Then, the piezoelectric device uses the distance as feedback control to compensate for the axial offset of the lens, thus realizing the focus-locking function. In the focal-locking part, the incident far-infrared laser (940 nm) is imaged as two spots on the CCD after total reflection at the interface between the specimen and cover glass, in which the distance between the two spots reflects the offset of the objective lens in the axial direction. To realize 3D single-particle imaging, we have added focus locking and two focal imaging apparatuses ( Figure 1). total internal reflection fluorescence (TIRF) objective lens and an ANDOR EMCCD (Ultra DU897). The 3D single-tracking system is built on an inverted Olympus IX73 microscope, which is equipped with a 60 × 1.45 N.A.
