A solution is proposed for testing a luminescence imaging apparatus (105). A corresponding method (700) comprises acquiring (706) a photograph image and finding (708) a position of the testing device (110) in the photograph image. The 5method further comprises acquiring (706) a luminescence image and determining (734-736) a representation of sites of the testing device (110), each comprising at least one luminescence substance, in the luminescence image according to the position of the testing device (110) in the photograph image.

A corresponding computer program (600) and a computer program product for implementing the method (700) are also proposed. Moreover, a testing device (110) for use in the method (700) is proposed.

A method of correcting an error of an optical sensor which includes a light source and a detector, including adjusting a brightness of the light source to a preset brightness; controlling the light source to emit light to a preset material; acquiring preset material data corresponding to the emitted light and the preset material using the detector; and correcting, by using the acquired preset material data, an error of a distance between the light source and the detector based on a difference between a first amount of light received at a first point of the detector and a second amount of light received at a second point of the detector, or based on a gradation of an image obtained by the detector

A method for determining instrument-dependent parameters of a surface plasmon resonance, SPR, biosensor system, and using those instrument-dependent parameters to measure the concentration of an analyte is provided herein. Also disclosed are methods of monitoring surface binding interactions of the analyte using the instrument-dependent parameters.

A method and a device for determining a degree of thermal hair damage are provided. A method for determining a degree of thermal hair damage includes, during exposure of a hair sample of hair to UV or UV/VIS light, recording a spectrum of at least a portion of the UV or UV/VIS light that has interacted with the hair sample. Further, the method includes comparing at least a portion of the spectrum with a spectroscopic calibration model obtained using UV or UV/VIS spectra and degrees of thermal damage of a plurality of calibration hair samples. Also, the method includes determining the degree of thermal hair damage by using the comparison.

A system for monitoring soil composition within a field may have a ground-engaging tool configured to engage soil within a field as an implement moves across the field. The system may further have a sensor configured to generate data indicative of a soil composition within the field, where the sensor is movable relative to the ground-engaging tool while the implement moves across the field such that the sensor generates data indicative of the soil composition at different depths within the field. Additionally, the system may have a controller communicatively coupled to the sensor, with the controller being configured to determine the soil composition at the different depths within the field based at least in part on the data received from the sensor.
