A biological component measurement apparatus includes an optical medium, a high thermal conductive film, an excitation light source, a probe light source, and a light position detector. The high thermal conductive film is higher in thermal conductivity than the optical medium, and is provided on a sample placement surface of the optical medium. The high thermal conductive film spreads heat generated from the sample irradiated with excitation light more in a first direction than in a second direction. The first direction is a traveling direction of probe light in plan view of the sample placement surface. The second direction is a direction orthogonal to the first direction in plan view of the sample placement surface.

A test device for testing an oxidation potential of an electrolyte is provided. The test device comprises a cavity, a test unit, a detector, a processing unit, and a display. The test unit comprises a positive plate comprising a first through hole, a negative plate comprising a second through hole, a first infrared window covering the first through hole, a second infrared window covering the second through hole, and an electrolyte located between the positive electrode plate and the negative electrode plate. The first through hole and the second through hole penetrate each other. The first infrared window, the positive plate, the negative plate, and the second infrared window are stacked with each other. An infrared light beam passes through the first infrared window, the first through hole, the electrolyte, the second through hole, and the second infrared window in sequence and then is detected by the detector.

This disclosure provides a method for imaging lymph nodes and lymphatic vessels without a contrast agent. The method includes providing, using an optical source, an infrared illumination to a region of a subject having at least one lymphatic component, detecting a reflected portion of the infrared illumination directly reflected from the region using a sensor positioned thereabout, and generating at least one image indicative of the at least one lymphatic component in the subject using the reflected portion of the infrared illumination.

A method is for determining the quality of an animal's semen. The method includes the steps of collecting at least one fresh or frozen semen sample, and measuring at least one absorption spectrum X.sub.j of at least one sample of the semen. The sample is collected to a straw for artificial insemination with animal semen obtained by implementing the method. A computer and software are used for the implementation of the method.

Systems and methods are provided for performing photothermal dynamic imaging. An exemplary method includes: scanning a sample to produce a plurality of raw photothermal dynamic signals; receiving the raw photothermal dynamic signals of the sample; generating a plurality of second signals by matched filtering the raw photothermal dynamic signals to reject non-modulated noise; and performing an inverse operation on the second signals to retrieve at least one thermodynamic signal in a temporal domain.
