RayCast around the object

Unity Engine
1

Hey, so i ran across this little problem, i dont know how to raycast around my player. At this point i can only raycast at the top, here is the example:

Heres the code, its pretty straitght Forward:

for(float i = 0; i < amount; i += 0.25f)
        {
            Vector2 pos = new Vector3(posX + i, posY, 0);
            RaycastHit2D hit = Physics2D.Raycast(transform.position, pos, distance);
            Debug.DrawRay(transform.position, pos, Color.red);

            if (hit.collider != null)
{
//More Code.....

The stealth tut should give you some ideas,

More or less uses a sphere collider than some vector math to figure out if the object is in the set field of view, than finally a raycast to make sure nothing is in between the player and ai.

Nah unfortunatealy thats not what i need, i need to get normals.
