  • Patent number: 11397311
    Abstract: Volumetric imaging with selective volume illumination (SVI) using light field detection is provided using various systems and techniques. A volumetric imaging apparatus includes a light source configured to emit an illumination light that propagates via an illumination light path to illuminate a three-dimensional (3D) sample; and an optical system arranged with respect to the light source to receive a light field, which comes from the illuminated 3D sample. The light field propagates via a detection light path, and the light source, the optical system, or both, are configurable to perform SVI, which selects a volume of a 3D-confined illumination of the 3D sample based on the 3D sample to be illuminated and a light field detection (LFD) process to be applied. Further, the volume of the 3D-confined illumination is a selected 3D volume of the 3D sample to be particularly excited by the 3D-confined illumination for imaging.

  • Patent number: 9971136
    Abstract: The invention relates to a method and a system to achieve spatially (e.g. three-dimensionally) confined photomodulation at the focal volume (50) in a ample (55) mounted in a microscope system, comprising two or more laser light sources (41, 42) emitting light (32, 34) of different wavelengths adapted to excite a material in an identical number of independent excitation steps to a higher vibrational state from which the material relaxes, either emitting a conversion light to be detected (“photoexcitation”) or modulating the spectral properties of the material (“photomodulation”).

  • Patent number: 8575570
    Abstract: An apparatus for and method of performing orthogonal light sheet microscopy (OLM) and computer optical tomography (COT) simultaneously in a single device are provided. The dual-mode imaging microscope allows for the use of both OLM and COT in a single instrument. This dual-mode device will allow researchers to have access to both types of microscopy, allowing access to the widest possible selection of samples, and improved imaging results. In addition, the device will reduce the high costs and space requirements associated with owning two different imagers (OLM and COT).

  • Patent number: 8441633
    Abstract: An apparatus for and method of performing multi-photon light sheet microscopy (MP-LISH), combining multi-photon excited fluorescence with the orthogonal illumination of light sheet microscopy are provided. With live imaging of whole Drosophila and zebrafish embryos, the high performance of MP-LISH compared to current state-of-the-art imaging techniques in maintaining good signal and high spatial resolution deep inside biological tissues (two times deeper than one-photon light sheet microscopy), in acquisition speed (more than one order of magnitude faster than conventional two-photon laser scanning microscopy), and in low phototoxicity are demonstrated. The inherent multi-modality of this new imaging technique is also demonstrated second harmonic generation light sheet microscopy to detect collagen in mouse tail tissue. Together, these properties create the potential for a wide range of applications for MP-LISH in 4D imaging of live biological systems.
