The OD-OCT system incorporates 256 custom-designed New Focus 2117 photoreceivers enabling the high-speed gathering and interpretation of data, with the optical demultiplexers simultaneously collecting an entire interferogram at different frequencies, instead of accumulating it over a certain time period. The high gain and low noise features of the New Focus detectors are critical in detecting low light level signals and generating high contrast images for accurate analysis. The New Focus photoreceiver is the market’s only available 10 MHz balanced detector with adjustable gain and bandpass filters, and offers flexibility and fine control of detectors not available in competing products.

With the innovative Oclaro New Focus balanced photoreceivers, which enabled our system to detect the 256 narrow spectrum bands of low light levels, our team at Kitasato University was able to create the fastest OCT system in the world, achieving a 60 MHz axial scan rate, said Prof. Kohji Ohbayashi, Kitasato University, Center for Fundamental Sciences.

Yves LeMaitre, General Manager of the Advanced Photonic Solutions division at Oclaro, said: We have been manufacturing and selling the New Focus balanced detectors and photoreceivers for over ten years and have the expertise to customise our products to meet the exact requirements of such demanding applications. We are proud to be involved in this breakthrough development and congratulate Prof. Ohbayashi and his team on their achievements.
