International Classification:

G01J 1/00
G01J 1/04
G01J 5/06
G01J 5/02
G01J 5/12

US Classification:

2503361, 2503381, 25033901, 25033902, 374142

Abstract:

In accordance with certain embodiments of the present disclosure, a method for adjusting the spectral detectivity of a thermal detector is described. The method includes coating the light sensitive portion of a thermal detector with a first material to reduce the response of the detector. The first material is coated with a second material that is thermally thin and has spectral absorption characteristics. The second material is coated with a third material that is thermally thick, whereby the spectral absorbance of the second material as filtered by the third material primarily determines the thermal conversion of the thermal detector.

G01J 5/02

US Classification:

348164, 2503381, 250351, 348E0509

Abstract:

A system and method for analyzing a sample is disclosed. At least a portion of the sample is illuminated with modulated light from a light source, such as an infrared light source. Infrared energy from the sample is monitored with an infrared detector as the sample is being illuminated with the modulated light. The AC response of the infrared energy is analyzed to determine at least one of emission data or reflection data about the sample. The emission data or the reflection data can be used to enhance chemical contrast between varying substances on the sample.

International Classification:

G01J 3/42

US Classification:

2503418, 2503381

Abstract:

Methods and systems for detecting the presence of a substance on a surface are provided. The method can include directing a modulated light beam (e.g., having a wavelength of about 3 to about 20 μm) from a light source to a beam expander such that the beam expander widens the diameter of the light beam into an expanded beam. The expanded beam can then be directed onto the surface to form an illuminated area. A specular reflection can then be detected from the illuminated area on the surface in each light cycle, and the presence of the substance on the surface can be determined.

International Classification:

G01N 21/55

US Classification:

2503418, 2503381

Abstract:

Methods and systems for detecting the presence of an inconsistency in or on a surface are generally provided. The method can include directing a modulated light beam (e.g., having a wavelength of about 3 μm to about 20 μm) from a light source to a mirror. The mirror then directs a reflected light beam onto the surface (e.g., directly onto the surface or indirectly onto the surface via a additional mirror(s)). The mirror is controlled to scan the reflected light beam across the surface. A specular reflection from the surface can then be detected in each light cycle, and the presence of the inconsistency on the surface can be detected.

G01N 33/49
G01N 1/30
B05D 3/00

Abstract:

A stain-barrier is described along with methods of its application to a fabric. The stain barrier reduces variability between samples of different dilution or fabric type so that limits of stain detection can be assigned more accurately and precisely and stain detection techniques can be transparently compared.

International Classification:

G01N 1/30
D06M 15/248

Abstract:

A stain-barrier is described along with methods of its application to a fabric. The stain barrier can be applied to fabric samples and limits the amount of fabric with which deposited liquid is able to interact. This stain barrier reduces unwanted variability between samples of different dilution or fabric type so that limits of stain detection can be assigned more accurately and precisely and stain detection techniques can be transparently compared.

International Classification:

G01N 25/72

US Classification:

374 5

Abstract:

Methods for identifying chemical contrasts on a common surface are generally provided. The presence of a stain on a surface can be detected by applying a testing vapor, such as water, onto the surface and monitoring the surface with an infrared camera that detects wavelengths of about 700 nm to about 1 mm and/or a microbolometer that detects wavelengths of about 7.5 μm to about 14 μm. The surface may be at room temperature or preheated during the detection method.
