Optical coherence tomography (OCT) probe and system designs are disclosed that minimize the effects of mechanical movement and strain to the probe to the OCT analysis. It also concerns optical designs that are robust against noise from the OCT laser source. Also integrated OCT system-probes are included that yield compact and robust electro-opto-mechanical systems along with polarization sensitive OCT systems. |

| Claim: |
1. An integrated optical system for detecting an interference signal generated by an OCT probe, the integrated optical system comprising: an hermetic package; an optical bench in the hermetic package; a detector system attached to the bench for detecting the interference signal; a beam splitter system attached to the bench that couples an OCT signal from a swept laser source to the OCT probe and couples the interference signal from the OCT probe to the detector system. |
| Claim: |
2. A system as claimed in claim 1, wherein the beam splitter system comprises a polarizing beam splitter for directing a first portion of the interference signal of a first polarization to a first interference detector of the detector system and second portion of the interference signal of a second polarization to a second detector of the detector system. |
| Claim: |
3. A system as claimed in claim 1, further comprising an amplitude detector for detecting a portion of the OCT signal received from the swept laser source. |
| Claim: |
4. A system as claimed in claim 1, further comprising a k-clock optical reference attached to the bench for spectrally filtering the OCT signal and a k-clock detector for detecting the OCT signal filtered by the k-clock optical reference to generate a k-clock signal. |
| Claim: |
5. A system as claimed in claim 1, further comprising a thermoelectric cooler in the hermetic package for controller the temperature of the optical bench. |
| Claim: |
6. An integrated OCT system, comprising: an hermetic package having an optical window; an optical bench in the hermetic package; a swept source laser system implemented on the optical bench for generating an OCT signal; a detector system attached to the bench for detecting an interference signal; and a beam splitter system attached to the bench that couples the OCT signal from the swept laser source through the optical window to an object of interest, couples a portion of the OCT signal to a reference arm, couples light returning from the reference arm to the detector system, and directs light returning from the object of interest to the detector system. |
| Claim: |
7. A system as claimed in claim 6, further comprising an amplitude detector attached to the bench for detecting a portion of the OCT signal from the swept source laser system. |
| Claim: |
8. A system as claimed in claim 6, further comprising a k-clock optical reference attached to the bench for spectrally filtering the OCT signal and a k-clock detector for detecting the OCT signal filtered by the k-clock optical reference to generate a k-clock signal. |
| Claim: |
9. A system as claimed in claim 6, further comprising a thermoelectric cooler in the hermetic package for controller the temperature of the optical bench. |
| Claim: |
10. A system as claimed in claim 6, wherein the beam splitter system comprises only a single beam splitter which is attached to the optical bench. |
