美國PhaseSpace
PhaseSpace專業提供高精度高實時性的主動式光學動作捕獲系統
PhaseSpace主動式光學動作捕捉/位置跟蹤系統PhaseSpace 公司總部位于美國San Leandro，從1994年開始研發并銷售主動式的光學運動追蹤系統，被廣泛的應用于科研、工業和數字媒體藝術等領域。PhaseSpace 動作捕獲系統通過使用特有的硬件與軟件技術，PhaseSpace 運動數字轉換器能夠捕捉復雜的運動。與那些擁有或主張現有運動跟蹤系統的供應商相比，PhaseSpace 利用擁有先進計算能力的光學技術，能夠得到較好的性能（如系統的分辨率，速度和測量范圍）。
PhaseSpace Inc. was founded in 1994 with the mission of developing new technologies and products for emerging motion tracking markets. Drawing upon the talents of a strong team of scientists and engineers from diverse technical backgrounds, PhaseSpace has developed motion capture solutions for the research, industrial and graphic arts communities.

The PhaseSpace Impulse System was developed as a new generation of 3D optical motion capture systems designed to be affordable to small companies, universities and individuals, lowering the cost of ownership so that it would be a financially feasible tool for a single artist or researcher.

The PhaseSpace system utilizes custom optics and camera technology that leverages Field Programmable Gate Array (FPGA) and synthesized digital signal processor (DSP) technology to deliver real time functionality at a new price threshold.

There are approximately a dozen relatively small companies participating in this market. Current full body optical systems are expensive at an average of $250,000 to $500,000 and do not meet the broad spectrum of customer requirements. Most systems from competitors require a dedicated staff for support and daily use. A complete system including workstation, software and studio modifications can increase the cost per application by several times the hardware costs.

PhaseSpace realized that simply reducing the cost of the hardware was not enough. Practical cost limitations indicate that systems not only need to be affordable to acquire, but that total cost of ownership must be low. Single-person use, ease of use in non-specialized settings, and removing lighting restrictions common to other motion-capture technologies, are critical to reducing overall cost of use. Users of the PhaseSpace system won’t need a dedicated room, with black walls and no other light source, and won’t need a team of operators to get the system up and running. Instead, any room in the user’s building will probably work, and can be set up to begin motion capture within an hour or so (often within minutes). PhaseSpace is the first to introduce a product that breaks the cost barrier with affordable hardware and affordable applications.
