The space-based astronomy telescope will observe ultra-faint objects whose brightness should be lower than 23th magnitude.To ensure telescope performance,ve
This paper introduces the research and design of laser triangulation measurement system based on linear array CCD,and the correctness of the theoretical ana
With the development of lighting technology,high-power white LEDs will become the future mainstream technology.At present,there are still many problems in o
In order to overcome current crowding and reduce the injection current underneath the opaque p-pad electrode in AlGaInP-based light emitting diodes(LEDs),a
We carried out In-diffusion annealing on Cd0.9Zn0.1Te under different temperatures,the nature of which is a process of diffusion and doping.By using In-diff
The determination of numerical reconstruction distance is key to recover the wavefront at focal plane in digital holography.In this paper,we propose a new a
We present evidence that transmission loss in gated x-ray framing cameras can affect relative gains.Transmission loss is caused by a variety of factors incl
A high average power and high beam quality nanosecond laser is presented that is based on CW diode side-pumped Nd:YVO4 grazing-incidence slab amplifier.A TE
