Confocal Fluorescence Microscopy

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Advanced Imaging

Background:

Frequency-modulated continuous wave (FMCW) light detection and ranging (lidar) is crucial for 3D imaging and autonomous driving.
Current FMCW lidar using soliton micro-combs offer multi-channel capabilities but are limited in range resolution due to narrow bandwidth.
A need exists for FMCW lidar systems with enhanced range resolution and high measurement rates.

Purpose of the Study:

To propose and demonstrate a novel FMCW lidar system utilizing cascaded modulator electro-optic (EO) frequency combs.
To overcome the range resolution limitations of existing soliton micro-comb based FMCW lidar.
To achieve massively parallel ranging with high resolution for advanced 3D imaging applications.

Main Methods:

Development of FMCW lidar systems employing cascaded modulator EO frequency combs.
Demonstration of a 31-channel system with a bulk EO frequency comb and a 19-channel system with an integrated thin-film lithium niobate (TFLN) EO frequency comb.
Analysis of sweep bandwidth limitations and performance evaluation through 3D imaging of a target.

Main Results:

Achieved a sweep bandwidth of up to 15 GHz per channel, enabling a 1-cm range resolution.
Demonstrated multi-channel FMCW lidar systems: 31-channel (bulk EO) and 19-channel (TFLN EO).
Attained a measurement rate exceeding 12 megapixels per second, confirming feasibility for massively parallel ranging.

Conclusions:

Cascaded modulator EO frequency combs significantly enhance FMCW lidar capabilities for massively parallel ranging.
The developed systems offer high range resolution and measurement rates, suitable for demanding 3D imaging tasks.
This approach holds potential for applications requiring high-resolution 3D imaging, including criminal investigation and precision machining.
