摘要： This method for evaluating an oxide semiconductor thin film includes evaluating the stress stability of an oxide semiconductor thin film on the basis of the light emission intensity of luminescent light excited when radiating an electron beam or excitation light at a sample at which the oxide semiconductor thin film is formed. The stress stability of the oxide semiconductor thin film is evaluated on the basis of the light emission intensity (L1) observed in the range of 1.6-1.9 eV of the luminescent light excited from the oxide semiconductor thin film.

摘要： An apparatus for and method of performing multi-photon light sheet microscopy (MP-LISH), combining multi-photon excited fluorescence with the orthogonal illumination of light sheet microscopy are provided. With live imaging of whole Drosophila and zebrafish embryos, the high performance of MP-LISH compared to current state-of-the-art imaging techniques in maintaining good signal and high spatial resolution deep inside biological tissues (two times deeper than one-photon light sheet microscopy), in acquisition speed (more than one order of magnitude faster than conventional two-photon laser scanning microscopy), and in low phototoxicity are demonstrated. The inherent multi-modality of this new imaging technique is also demonstrated second harmonic generation light sheet microscopy to detect collagen in mouse tail tissue. Together, these properties create the potential for a wide range of applications for MP-LISH in 4D imaging of live biological systems.

摘要： There is provided a system and method for providing and utilizing objects having invisible three-dimensional images. There is provided an object comprising an inner material and an outer material. The inner material is formed in a three-dimensional shape and includes a first portion having a first ratio based on a first fluorescent dye and a first transparent material, wherein the first ratio is selected such as to cause the first portion to remain transparent when exposed to a visible light and the first portion to emit a first visible color when exposed to an invisible light. The outer material comprises a second transparent material formed around the inner material such as to hide the three-dimensional shape of the inner material. By exposing the object to the invisible light, the three-dimensional shape of the inner material is revealed.

摘要： A method for detecting traces of material on a surface for forensic evidence gathering is disclosed. The surface is periodically illuminated with laser radiation. Pairs of images of the surface are recorded with one image in each pair recorded while the surface is illuminated and the other being recorded while the surface is not being illuminated. The images in each pair are subtracted and a video signal is generated from the subtracted images. The video signal can be displayed on a display device or recorded for later display and examination.

摘要： The invention relates to a method for optically detecting at least one entity which is arranged on a substrate. The at least one entity is scanned with a measuring volume using at least one radiation source and a confocal optic. During a scanning process an auxiliary focus is generated by means of at least one second radiation source and a second optic. Radiation generated by the first radiation source is collimated by a first optic and radiation generated by the second radiation source is collimated by a second optic. A retroreflection from the auxiliary focus is detected by at least one detector and is used to measuring the position of an interface and, thus, for indirectly positioning the measuring volume. The position of the auxiliary focus relative to the measuring volume is adjustable in a defined manner.
