Abstract
An optical apparatus for measuring the velocity of flowing biomaterials is disclosed, which has a coherent light source for projecting a light beam with low coherent length; a reference member having mirrors for periodically reflecting lights thereon; a photo detector for receiving photo signals; a splitter for splitting said light beam from said coherent light source into a reference beam and a detecting beam. The disclosed optical apparatus can save the time for complicate computation and the cost of software or hardware for measuring the flowing velocity of biomaterials, especially the flowing velocity of flowing bloods in vessels.
Claims15
An optical apparatus for measuring the velocity of flowing biomaterials, comprising:
- a coherent light source for projecting a light beam with low coherent length;
- a reference member having mirrors for periodically reflecting lights thereon;
- a photo detector for receiving photo signals;
- a splitter for splitting said light beam from said coherent light source into a reference beam and a detecting beam;
- wherein said splitter is located between said photo detector and said reference member, said reference beam from said splitter projects on said reference member and reflects back to said photo detector by the refection of said splitter;
- said detecting beam from said splitter projects on said biomaterials and reflects back to said photo detector by the refection of said splitter;
- and at least one location of said reference member relative to said splitter is applied as the velocity of said biomaterials flow is measured.
