Research Abstract

This research intends to achieve high-bandwidth three-dimensional micro imaging by fusing the idea of wavelength-domain multiplexing of light-wave and two-dimensional space-domain parallelism. For realize high-throughput systems, we need various new sub-system technologies concerning the essential properties of two-dimensional parallel optical devices, diffractive optical elements, integrated circuits, and so forth. In particular, the parallel structure, which is indispensable to achieve high-throughput, imposes new requirements to optical system designs. For example, in a conventional microscope objective, off-axis beams from a laser cannot be imaged onto a proper imaging position due to severe distortion of the lens system where the off-axis beam probing is not supposed. Clearly, a system-level problem occurs due to the introduction of parallelism into imaging applications.
To solve such problems, we developed active alignment for the purpose of parallel system stabilization, optimal lens design for parallel confocal imaging, and data processing by using computational sensor array which is directly adapted to a parallel imaging optics. The active alignment was experimentally demonstrated where 118 Hz environmental disturbance was successfully reduced. Also, by employing H-infinity theory, we also realized to integrate the dynamics of the controller and disturbance for the operation of the active alignment. For the parallel confocal imaging system was developed by reducing distortion and astigmatic aberrations, which supports up to 3,200 parallel channels if we assume 250um pitch for the confocal microscopy.
