Ultra-high Speed OCT Technology
We have developed the world's fastest spectral domain (SD) OCT system, which enables an axial scan (A-scan) rate of 60,000,000 per second. With the system, 3D OCT imaging,
at a rate even faster than the conventional video rate of 30 frames per second, is possible.Link_JST
Real-time 4D OCT Display Technology
We have enabled display of real-time 3D OCT motion picture (4D-OCT) at a volume rate even exceeding the usual video rate. Real-time image manipulations are possible such as rotation,
and partial image cutting. Image cutting in an arbitrary form enables a virtual surgery. The system is also possible logging a 4D OCT movie longer than 100 minutes.
Akinetic VT-DBR Laser and SS-OCT Technology
OCT methods are classified into Time Domain (TD) OCT and Fourier Domain (FD) OCT. If compared at the same data acquisition speed、 FD-OCT is more sensitive than TD-OCT.
Of the two FD-OCT methods, the coherence length is longer in Swept Source (SS) OCT than in Spectral Domain (SD) OCT. Therefore, SS-OCT methods have come more common in OCT
An SS-OCT source of single longitudinal mode is preferred compared with that of multi-longitudinal mode, because the depth range is not restricted by the cavity length of
the source. The Vernier Tuning (VT)−DBR（Distributed Bragg Reflector）laser operates in single longitudinal mode, has very long coherence length, switches fast, akinetic without any
mechanical movable part, has long life-time, and sold for the telecommunication market in low cost. Therefore, it is expected as an ideal SS-OCT source. We were the first
to propose and demonstrate the usefulness of VT-DBR lasers for SS-OCT more than about ten years ago. Based on the accumulated experiences, we shall collaborate on VT-DBR-SS-OCT.
Very fast VT-DBR sources for SS-OCT are currently developed and shall be released soon for sale.
OCT Tecnologies in General
Based on technological know-how accumulated during development of ultra-high speed OCT and VT-DBR-SS-OCT, we shall collaborate on OCT technologies in general.
We shall co-work with
Systems Engineering Co. Ltd. for manufacturing OCT systems.
