In one embodiment, a system includes a sight tube configured to optically communicate with an interior of a rotary machine via insertion within an inspection port. The sight tube includes a window and multiple openings configured to direct purge air across the window. The system also includes a curtain tube disposed about the sight tube and configured to direct purge air from a first air source to the openings via a first passage formed between an inner surface of the curtain tube and an outer surface of the sight tube. The curtain tube includes multiple outlets configured to direct curtain air around the window, and the curtain tube is configured to direct the curtain air from a second air source to the outlets via a second passage formed between an outer surface of the curtain tube and an inner surface of the inspection port.

A thermal measurement system includes a number of detectors configured to receive radiation within respective wavelength ranges. The system also includes a mirror configured to selectively direct the radiation from an object to each of the detectors. The system further includes an actuator mechanically coupled to the mirror and configured to rotate the mirror through a number of angles. The system also includes an optical and probe subsystem disposed between the object and the mirror to focus the radiation on to the mirror.

A thermal measurement system for an object is provided. The system includes an array of detectors in two dimensions configured to receive radiation within multiple wavelength ranges, the array of detectors having a first axis representing a spatial dimension and a second axis representing a wavelength dimension. The system also includes an optical system configured to focus the radiation emitted by the object on to the array of detectors.
摘要:
An optical sensor system includes a multi-color pyrometer in optical communication with a component. The pyrometer generates signals at least partially representative of radiation received from the component and from soot particles. The system includes at least one processing unit coupled to the pyrometer. The processing unit is programmed to receive the signals and distinguish portions of radiation received between at least two wavelength bands. The processing unit is also programmed to determine that a first portion of radiation within a first of the wavelength bands is representative of a temperature of soot particles and that a second portion of radiation within a second of the wavelength bands is representative of a temperature of the component. The processing unit is further programmed to filter out signals representative of the first portion of the radiation.
