how can i see infrared

Hello all.
Can any one help me? How can I see infrared beam, radiate?
How can I do reflection? I want to radiate of ir beam just like as laser beam.

I'd love to help you, but I'm not sure of your question.

You cant 'see' IR with your eyes. A thermal imaging camera will go some way to do this.
A reflective surface will reflect IR to some extent.

Near IR as emitted by IR LEDs can be visualized with special IR indicator cards. Near IR optical behaviour is almost identical to visible light.

You can see it with any CCD camera which is sensitive to IR. If fact this principle is used to obtain "night vision".

Use your cellphone's cam to see if the IR led is on, but you won't see a beam like laser beam but like a led's light instead

The interesting part of the question is the word 'see'... is like you ask question "how can I see a sound wave?".

Naah, just my thought.

Use a photocell, connected to a volt meter, from there you can detect and measure the intensity of the IR source... in a closed dark room of course, else you should calculate some compensation and... naaaahhh too long...hehehe, good luck.
