Claims20
An optical blood vessel enhancing system for identify a blood vessel underlying within a target area, the system comprising:
- a. a light source configured to selectively transmit incident light within the infrared spectrum onto said target area, said light source comprising at least one wavelength;
- b. an optical sensor responsive to said infrared spectrum light, wherein said optical sensor is configured to receive light reflected from said target area therein forming a contrasted image based on said reflected light and at least a selective portion of said incident light;
- c. a controllable optical enhancer in the form of a controllable polarizer provided for controlling the optical properties of at least one of said incident light and/or said reflected light;
- and
- d. a processor functionally coupled with said optical sensor for enhancing said contrasted image to identify a blood vessel with said target area by distinguish between a potential blood vessel from surroundings target area;
- and for controlling said controllable light filter.
