Abstract
An optical scanning system for examining material associated with a substrate includes at least one scanning module for displacing two or more objective lenses, at least one optical coupling system and a translation system. The two objective lenses are mounted on one or more scan arms and are constructed to scan over regions or subregions associated with the substrate. The scanning module is configured to displace the scan arm(s) to perform the scan and thereby displace the two objective lenses. Each objective lens is arranged to deliver light to the material and collect light from the material.
Claims38
An optical scanner, comprising:
- at least a first and a second objective lens mounted on at least one scanning module, wherein each at least one scanning module comprises at least one motor, at least one scan arm and at least one of the objective lenses;
- an optical coupling system comprising a light source and at least a first and second detector, wherein said optical coupling system is configured to deliver light from said light source through said at least two objective lenses to a substrate and detect light from said substrate collected by said at least a first and a second objective lens, and wherein said first detector detects light from said first objective lens and said second detector detects light from said second objective lens and so on;
- and
- a translation mechanism constructed for relative movement of said substrate and said scanning module.
An optical scanner, comprising:
- a first and a second scanning module, wherein each of said scanning modules comprises a motor, a scan arm and an objective lens;
- an optical coupling system comprising a light source and a first and a second detector, wherein said optical coupling system is configured to deliver light from said light source through said first and second objective lenses to a substrate and detect light from said substrate collected by said first and second objective lenses, and wherein said first detector detects light from said first objective lens and said second detector detects light from said second objective lens;
- and
- a translation mechanism constructed for relative movement of said substrate and said scanning module.
An optical scanning method for examining biological material, comprising the acts of:
- providing two objective lenses mounted on at least one scanning module, wherein each of said at least one scanning module comprises at least one motor, at least one scan arm and at least one of the at least one objective lenses;
- generating light of a selected wavelength and coupling said generated light to said two objective lenses;
- displacing said at least one scanning module on a scan path over biological material disposed on regions of a substrate;
- irradiating said biological material by light from each objective lens;
- collecting light from said biological material by each objective lens;
- detecting by a separate detector light collected from each objective lens;
- and
- analyzing said biological material based on said light detected by said detectors.
