When the airborne platform
where installed the optical window
is in high Mach flight condition. The aerodynamic heating effect
which will influence optical properties of optical window
becomes very obvious. This special flight condition will change shape
refractive index and also refractive index distribution of optical window due to the generated high axial temperature gradient. To ensure image quality of aerial remote sensor
the present paper does thermal-optical analysis for optical window under high Mach flight condition. Then
on this basis
do simulations according to theoretical analysis and boundary conditions derived from practical assumptions in order to get the final conclusions. 2012 IEEE.

A review of high-speed flow pressure and aerodynamic heating effect on Supersonic missile's dome is given. The dome should have excellent properties in optical
mechanical and chemical characteristics. A design of dome on supersonic mode is described according to tactical guide line of a missile. The dome made of quartz which is about 8mm thick and 141mm in window diameter. To check up the reliability of the dome
a reasonable finite element model (FEM) of dome is established
and a thermal-mechanical Analysis to the dome by finite element software NASTRAN has carried on
through these can obtained the distribution of temperature field and stress field when the speed is 2.3Ma. The results indicated that the stress was concentrated in the joint of the dome end and the Missile Section
and the maximum stress was 16.4Mpa. The stress of other nodes was smaller than the allowable stress of quartz glass. Reference to the results of the analysis
a lightweight revision to the dome structural dimension and a new method of dome fixing have put forward
which can reduce the stress concentration. 2009 SPIE.

High power laser diode array with an emission wavelength of 1064nm is presented. The epitaxial structure is an InGaAs/GaAsP strained-compensated single-quantum well structure. The modules CW output power can reach to 56.5W at current of 80A. Because the heat capacity of st rather shorter pulse duration and lower duty cycle
the average driving power in the laser chip is quite low
so the heating effect cemiconductor laser is very small
using pulse injection can reduce temperature rising significantly. Aould be neglected. The definite relation between lasing wavelength and chip temperature is developed. The temperature drift coefficient is 0. 45nm/K 2008 SPIE.

RF hyperthermia system is a kind of medical device to restrain and kill cancer tumor base on RF heating technique and biology heating effect theory. The mathematical model of the control system is very difficult to be formed due to the extreme complication physical process of temperature increase during the thermal treatment and the various structure and characteristic of internal tissues. In this paper
we present a new fuzzy control algorithm
in which a self-regulation factor is adopted to realize real-time temperature control with high-precision controller. By means of software arithmetic and hardware adjustment
accurate temperature and time control can be achieved in this system. 2007 IEEE.
