Upcoming:  Integrated High-Speed, High-Resolution Measurement

. . . Why Integrated High-Speed, High-Resolution Measurement Matters
  • Dual-purposing the laser’s existing A/D converters cuts system cost
  • One, two or three channels of simultaneous measurement
  • 14-bit high resolution
  • 400 MHz data acquisition
  • Built-in, configurable signal conditioning with>200MHz bandwidth
  • Low noise
  • Tightly integrated with laser operation
  • Onboard FFT and auto-zero and auto-correction
  • Substantially reduce system cost
  • Reduce development cost and time
  • Reduce system size and complexity
  • Faster time to market
  • A complete OCT engine; just add your sensor and imaging visualization software
  • Improve measurement performance
  • Reduce cost of goods, improving margins or reducing price to increase penetration

 

The following capabilities will be available over the next several months.  If you are interested, contact Insight Applications Engineering to be part of the rollout process for Insight’s integrated measurement.

 

Dual-purposed A/D Converters Mean System Cost Savings
The Insight laser uses high speed A/D converters internally.  We can dual-purpose those converters, giving you access to your data acquisition without a lot of added cost.  By adding high-speed 1 GB or 10 GB Ethernet communications and linkage through our DSP, the laser engine now provides both sourcing and measurement, at an overall system cost savings. 

 

One, Two or Three Converters
For traditional OCT, a single converter may be all that is necessary.  For multi-path OCT applications, such as polarization sensitive, or multi-angle or multi-focal length, more than one converter can be advantageous (note that for some of these applications, when used with the Insight laser high coherence length, delay paths may be used to put the signals on a single fiber without the need for multiple converters). 

 

14-bit, 400MHz High-Resolution Conversion
The higher quality optical signal and resulting PSF on akinetic lasers can then allow the effective use of higher resolution detection.  And the higher resolution can still be at a discount to lower 12-bit conversion.  Good SNR.  Data conversion up to 400MHz.

 

On-board Optional Processing
You can do all the signal processing, or you can have the laser data acquisition do the initial signal processing, including the FFT and windowing.

 

Faster Time-to-Market
If you can use the integrated measurement, your OCT system development may be faster and lower development expense.  This can allow you to focus on your critical software and optical scanning systems, where you add substantial value.

 

Measurement Rate to 40 0MHz*
The core triggering rate of the laser is 400MHz.  This means you can do any of the following:

Up to 400 kHz @ up to 1,000 points
Up to 200 kHz @ up to 2,000 points
Up to 100 kHz @ up to 4,000 points
Up to 50 kHz @ up to 8,000 points
Up to 20 kHz @ up to 20,000 points
Up to 10 kHz @ up to 40,000 points
An so on.

The measurement itself can be adjusted down from 400 MHz.   Accessible rates include 400, 200, 133, 100, 80, 66, 50, 44, and 40 MHz.

As discussed in the electronic k-clock section, the laser provides the triggers for your data acquisition system.  Learn more about the electronic k-clock and triggering jitter in the linearity section.
