A new time-domain two-dimensional fluorescence lifetime detection method and a fluorescence lifetime imaging microscope that is based on a synchroscan streak camera are presented. This system can generate in parallel a complete two-dimensional fluorescence lifetime image without scanning the light. We demonstrate the acquisition of a fluorescence lifetime image of a semiconductor ET material sample at a temporal resolution of 2ps and spatial resolution of 4µm within 40ms.

Recently ultra fast diagnostic techniques have been developed to investigate imploded core plasma of shell-cone target for fast ignition in laser fusion research. One and two dimensional x-ray image sampling and two dimensional image reconstruction techniques have been applied to x-ray streak cameras. Multi-imaging x-ray streak(MIXS) camera, sampling image x-ray streak camera and multichannels MIXS camera employing pinholes and pinhole arrays coupled with x-ray streak camera were used in implosion experiment of a shell target with a cone. The reconstructed 2D images have shown the different evolutions of core plasmas for all kinds of cases. The interaction between the core plasma and the tip of the cone was observed and revealed some detailed structures. The time-resolved plasma temperature has been derived from the McMIXS's image.

The ultrafast imaging methods in sliced sampling streak cameras are investigated. It is shown that the sampling-image x-ray streak camera has potential advantages in highly time-resolved and space-resolved imaging for imploded core plasmas. An optimized sampling method is presented to acquire two-dimensional spatial resolutions ഛ10 m and temporal resolution ϳ10 ps, within a field of view ϳ100 m and a time range ϳ100 ps.In experimental studies of inertial confinement fusion, time-resolved and two-dimensionally ͑2D͒ space-resolved x-ray imaging is routinely employed to observe the evolution of imploded core plasmas. 1-3 The typical size of core plasmas is ϳ100 m and the time duration of either its selfemission or a short-pulse x-ray backlighter is ϳ100 ps. Therefore, it is necessary to develop x-ray cameras with both 2D spatial resolution ഛ10 m and temporal resolution ϳ10 ps. Spatial resolution is achieved with x-ray optics, such as pinholes, or Kirkpatric-Baez ͑KB͒ microscopes. 4-8 It is difficult to reach a spatial resolution better than 10 m with pinholes, due to the diffraction limit. However, the spatial resolution of grazing incidence KB mirrors can be better than 5 m ͑even down to 2 m͒. [5][6][7][8] There have been two types of x-ray cameras, i.e., gated framing cameras 7,8 and sliced sampling streak cameras, [9][10][11][12][13][14] which have the capacity of both temporal resolution and 2D spatial resolutions. However, all these cameras have to face the same problem, i.e., one space dimension must be shared with the time on the recording page ͓e.g., charge-coupled device ͑CCD͔͒. In gated framing cameras, the 2D image on each frame is selected with a traveling gate pulse. The temporal resolution is limited by the time frame ͑35-80 ps͒ and the time interval between frames ͑50-100 ps͒. With KB mirrors as optics, 8 the spatial resolution better than 5 m has been realized, however, which can be degraded, due to motion blurring. In the sliced sampling streak cameras, a temporal resolution of ϳ10 ps or even ϳ1 ps can be obtained. But some special sampling methods must be employed to acquire the 2D space resolutions at the same time. In general, the 2D image is periodically sampled with slits on an opaque sampling mask, or equivalently so, which is located in front of the streak cathode. All the selected one-dimensional ͑1D͒ samples can then be simultaneously swept, without overlapping on the recording page, because each of them has an independent recording region, due to the mask shielding. To date, there have been two such cameras, i.e., multi-imaging x-ray streak ͑MIXS͒ camera 9-12 and sampling-image x-ray streak ͑SIXS͒ camera. 13,14 Though the previous SIXS camera employed a sampling mask with pinhole arrays, it can be viewed as modification from a mask with slits. In this letter, we try to investigate the 2D sampling methods demonstrated in the MIXS and SIXS cameras. An optimized method is presented for constructing a practical sliced sampling streak camera with required time resolution and 2D space resolution...
