چکیده
We have constructed a near-infrared imaging camera which is attached to the prime focus of 105cm Schmidt telescope at Kiso Observatory. The camera is equipped with a 10401040 PtSi CSD array developed by Mitsubishi Electric Co. The combination of Kiso Schmidt and the array gives a wide eld of view of 18:4 0 18:4 0 with a reasonable spatial resolution of 1:06"=pixel. The system performances of the camera have been evaluated through laboratory and observational tests. Low noise, good cosmetics(no defect pixels), and good stability of the camera system show an excellent performance for astronomical use.

Improving 3-D Imaging Breast Cancer Diagnosis Systems Using a New Method for Placement of Near-Infrared Sources and Detectors
The objective of this research was to improve 3-D imaging system by near-infrared light emission in breast tissue to achieve a more accurate diagnosis of tumor. The results of repeated experiments in this research have shown that with this imaging system, a more accurate diagnosis of abnormal area depends on the location of the sources and detectors. Therefore, an optimal location model has bee...
متن کاملProposed instrumentation for PILOT
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed Australian/European optical/infrared telescope for Dome C on the Antarctic Plateau, with target first light in 2012. The proposed telescope is 2.4m diameter, with overall focal ratio f/10, and a 1 degree field-of-view. In median seeing conditions, it delivers 0.3" FWHM widefield image quality, from 0.7-2.5 microns...
متن کاملSpectroscopic near-field microscopy using frequency combs in the mid-infrared.
We introduce a new concept of spectroscopic near-field optical microscopy that records broad infrared spectra at each pixel during scanning. Two coherent beams with harmonic frequency-comb spectra are employed, one for illuminating the scanning tip, the other as reference for multi-heterodyne detection of the scattered light. Our implementation yields 200 cm(-1) wide amplitude and phase spectra...
متن کاملNew trends in near-infrared fluorophores for bioimaging.
This review summarizes progress in the field of near-infrared (NIR) fluorophores achieved during the last decade from the viewpoint of chemistry. Those compounds are of wide interest in bioanalysis and bioimaging, such as in vivo fluorescence imaging. Particular focus is placed on the recent developments of BODIPY and rhodamine derivatives, which belong to the most evolved NIR fluorophores. The...
