Abstract
An apparatus includes a wavelength swept light source to generate a measurement beam, a scanner to move the measurement beam on a sample, a measurement device to measure the sample, and a safety device to stop the light source based on sweeping status of the light source.
Claims29
An apparatus comprising:
- a flexible member having a hollow cavity extending between a proximal end and a distal end;
- a wavelength swept light source to generate a measurement beam;
- a scanner to move the measurement beam on a sample;
- a measurement device to measure the sample;
- and
- a safety device to stop the light source based on sweeping status of the light source,
- wherein the safety device monitors the light source and determines the sweeping status of the light source with the safety device, wherein the light source sweeps at a predetermined frequency (wavelength sweep rate) within a predetermined wavelength range.
