Compact low-cost detection electronics for optical coherence imaging

Area of Science:

• Biomedical Optics
• Instrumentation
• Signal Processing

Background:

• Optical coherence imaging requires sophisticated detection electronics.
• Commercial systems can be expensive and complex.
• There is a need for cost-effective and compact imaging solutions.

Purpose of the Study:

• To demonstrate a compact and low-cost detection electronics scheme for optical coherence imaging.
• To evaluate the performance of the developed electronics.
• To compare the system's performance against a commercial lock-in amplifier.

Main Methods:

• Design and implementation of a novel detection electronics scheme.
• Performance analysis using quantitative metrics.
• Comparative imaging of a biological sample (fresh onion).

Main Results:

• The developed electronics scheme is compact and low-cost.
• Performance is comparable to a commercial lock-in amplifier with equal bandwidth.
• High-quality images of a fresh-onion sample were obtained.

Conclusions:

• The demonstrated electronics scheme is a viable and cost-effective alternative for optical coherence imaging.
• This approach can potentially lower the barrier to entry for optical coherence imaging technologies.
• Further optimization may enhance performance for advanced applications.
