Technology Description
We have devised a complete pipeline of light-sheet microscopy, encompassing sample clearing and staining, fully automated high-resolution high-speed imaging, and teravoxel image processing. The microscopy pipeline makes it possible to analyse macroscopic tissue samples at sub-cellular resolution. Our system has two fundamental advantages: first, imaging quality is always kept high thanks to automated feedback systems for light-sheet stabilization and autofocusing. Second, a dedicated set of software tools enables management and effective access to teravoxel-sized images, allowing subsequent data analysis.
Competitors do not provide any active stabilization of the light sheet, requiring continuous adjustment of imaging parameters by the user. Neither do they provide links between the imaging system and image analysis tools.

Tight interconnection between the imaging system and image analysis tools ENABLES effective management of teravoxel-sized imaging datasets

WITH THE RAPID TECHNOLOGY...

1. RAPID overcomes limitations of current autofocus systems for microscopy

2. RAPID provides real-time operation without any reference reflection

3. A single solution can be used for all wide-field microscopes
1. We devised a new method for focus stabilization in optical microscopy. Standard methods rely either on contrast optimization (thus working offline) or on triangulation (requiring a reflective surface).
2. RAPID (Rapid Autofocus via Pupil-split Image phase Detection) extends to the entire field of view of the instrument the phase-detection principle, which is limited to selected points of interest in professional photography.
3. This method allows direct evaluation of the defocusing state of the system simply using the detected image. Therefore, RAPID is completely agnostic with respect to sample or microscope, and can be applied to all systems, in all settings.
