Patent number: 10555669Abstract: An optical coherence tomography (OCT) interferometer includes at least a first optical fiber of a first type having a first length, in series with a second optical fiber of a second type which is different than the first type and having a second length, in at least one of the sample path and/or the reference path of the OCT interferometer. The dispersion characteristics of the first optical fiber and the second optical fiber are significantly different than each other.

Optical measurement system and method including blink rate monitor and/or tear film breakup detector
Patent number: 10098534Abstract: An optical measurement system and method measure a characteristic of a subject's eye. The optical measurement system receives from an operator, via a user interface of the optical measurement instrument, a begin measurement instruction indicating the start of a measurement period for objectively measuring at least one characteristic of the subject's eye. Subsequent to receiving the begin measurement instruction, the optical measurement system determines whether a criterion associated with the tear film quality of the subject's eye is not satisfied. In response to determining that the criterion is not satisfied, the optical measurement instrument takes one or more corrective actions to measure the characteristic of the subject's eye under a condition wherein the criterion is satisfied.Type: GrantFiled: July 11, 2017Date of Patent: October 16, 2018Assignee: AMO WAVEFRONT SCIENCES, LLCInventors: Richard J.
