Abstract
A temperature controlled welding, soldering and heating system having a plurality of light sources of different wavelengths for simultaneously irradiating a tissue sample and an IR radiometer for providing tissue sample temperature reading in real time, the temperature readings used for controlling the light sources. In a preferred embodiment, the sample is a tissue sample and the light sources are lasers.
Claims20
A system for non-contact welding, soldering and heating of a tissue sample, comprising:
- a. a plurality of light sources each having a different wavelength, the sources operative to simultaneously irradiate the tissue sample thereby causing heating;
- and
- b. an IR radiometry subsystem for monitoring the IR radiation emitted from the tissue sample during the heating and for providing respective IR radiation inputs for control of each of the light sources.
A non-contact welding, soldering and heating system comprising:
- a. a plurality of light sources for simultaneously and controllably irradiating and heating a tissue sample;
- b. an infrared detector for monitoring IR radiation emitted from the tissue sample during the heating in at least one spectral band and for providing respective IR radiation inputs;
- and
- c. a controller for controlling each of the light sources based on the IR radiation inputs, thereby facilitating the controllable heating of the tissue sample.
